COMPOSITIONS AND METHODS FOR TREATING SEVERE PAIN

[01] This continuation-in-part application claims priority pursuant to 35 U.S.C. § 120 to patent application US 13/365,824, filed February 3, 2012, a continuation-in-part application that claims priority to patent application PCT/GB2011/052115, filed October 31, 2011, an international patent application that claims priority to GB 1018289.7, filed October 29, 2010, and claims priority to patent application US 13/365,828, filed February 3, 2012, and claims priority to GB 1113730.4, filed August 10, 2011, GB 1113729.6, filed August 10, 2011, GB 1113728.8, filed August 10, 2011, and GB 1101937.9, filed February 4, 2011, each of which is hereby incorporated by reference in its entirety.

[02] Pain is a subjective and very complex perception that signals to an individual that tissue damage has occurred or may be occurring. Pain may be transitory, lasting only until the noxious stimulus causing the pain is removed or the underling damage or pathology has healed or may lasts beyond the healing of an injury, continuing for a period of several months or longer. A pain response has both physiological as well as psychological components. A pain response evokes a wide range of sensations that may be described as a dull, aching sensation, a sharp stabbing sensation, a hot, cold, or icy-hot sensation, a tingling or itchy sensation or a numbness. Pain can be felt in one area of the body, such as your back, abdomen or chest or throughout the body, such as when all the muscles in a body ache from the flu.

[03] Severe pain is the most common reason for an individual to consult a healthcare provider in the United States. It is a major symptom in many medical conditions, and can significantly interfere with a person's quality of life and general functioning. As such, severe pain is a significant and costly healthcare problem.

[04] Current therapies for treating severe pain are limited, often involving the administration of multiple medications with the understanding that pain relief will not be complete and the quality of life may not be restored. These therapies may require frequent dosing, can be associated with undesirable systemic side effects, and typically provide unsatisfactory relief. Therefore, there remains a need for a therapeutic option developed specifically for severe pain that provides sustained relief while minimizing the potential for systemic side effects and drug-drug interactions.

[05] The present specification discloses pharmaceutical compositions and methods for treating an individual suffering from a severe pain condition. The pharmaceutical compositions disclosed herein are essentially a lipid delivery system that enables a therapeutic compound having anti-pain activity to be delivered in a manner that more effectively inhibits a pain response. The end result is an improved treatment for a severe pain condition.

DESCRIPTION

[012] Aspects of the present specification disclose, in part, a composition. A composition disclosed herein is generally administered as a pharmaceutical acceptable composition. As used herein, the term "pharmaceutically acceptable" refers any molecular entity or composition that does not produce an adverse, allergic or other untoward or unwanted reaction when administered to an individual. As used herein, the term “pharmaceutically acceptable composition” is synonymous with “pharmaceutical composition” and means a therapeutically effective concentration of an active ingredient, such as, e.g., any of the therapeutic compounds disclosed herein. A pharmaceutical composition disclosed herein is useful for medical and veterinary applications. A pharmaceutical composition may be administered to an individual alone, or in combination with other supplementary active ingredients, agents, drugs or hormones.

[013] A pharmaceutical composition disclosed herein may optionally include a pharmaceutically-acceptable carrier that facilitates processing of an active ingredient into pharmaceutically-acceptable compositions. As used herein, the term “pharmacologicaily-acceptable carrier” is synonymous with “pharmacological carrier” and means any carrier that has substantially no long term or permanent detrimental effect when administered and encompasses terms such as “pharmacologically acceptable vehicle, stabilizer, diluent, additive, auxiliary or excipient.” Such a carrier generally is mixed with a therapeutic compound or permitted to dilute or enclose the active compound and can be a solid, semisolid, or liquid agent. It is understood that a therapeutic compound or other active ingredient can be soluble or can be delivered as a suspension in the desired carrier or diluent. Any of a variety of pharmaceutically acceptable carriers can be used including, without limitation, aqueous media such as, e.g., water, saline, glycine, hyaluronic acid and the like; solid carriers such as, e.g., mannitol, lactose, starch, magnesium stearate, sodium saccharin, talcum, cellulose, glucose, sucrose, magnesium carbonate, and the like; solvents; dispersion media; coatings; antibacterial and antifungal agents; isotonic and absorption delaying agents; or any other inactive ingredient. Selection of a pharmacologically acceptable carrier can depend on the mode of administration. Except insofar as any pharmacologically acceptable carrier is incompatible with the active ingredient, its use in pharmaceutically acceptable compositions is contemplated. Non-limiting examples of specific uses of such pharmaceutical carriers can be found in Pharmaceutical Dosage Forms and Drug Delivery Systems (Howard C. Ansel et al., eds., Lippincott Williams & Wilkins Publishers, 7th ed. 1999); REMINGTON: THE SCIENCE AND PRACTICE OF PHARMACY (Alfonso R. Gennaro ed., Lippincott, Williams & Wilkins, 20th ed. 2000); Goodman & Gilman's The Pharmacological Basis of Therapeutics (Joel G. Hardman et al., eds., McGraw-Hill Professional, 10th ed. 2001); and Handbook of Pharmaceutical Excipients (Raymond C. Rowe et al., APhA Publications, 4th edition 2003). These protocols are routine procedures and any modifications are well within the scope of one skilled in the art and from the teaching herein.

[014] A pharmaceutical composition disclosed herein can optionally include, without limitation, other pharmaceutically acceptable components (or pharmaceutical components), including, without limitation, buffers, preservatives, tonicity adjusters, salts, antioxidants, osmolality adjusting agents, physiological substances, pharmacological substances, bulking agents, emulsifying agents, wetting agents, sweetening or flavoring agents, and the like. Various buffers and means for adjusting pH can be used to prepare a pharmaceutical composition disclosed herein, provided that the resulting preparation is pharmaceutically acceptable. Such buffers include, without limitation, acetate buffers, citrate buffers, phosphate buffers, neutral buffered saline, phosphate buffered saline and borate buffers. It is understood that acids or bases can be used to adjust the pH of a composition as needed. Pharmaceutically acceptable antioxidants include, without limitation, sodium metabisulfite, sodium thiosulfate, acetylcysteine, butylated hydroxyanisole and butylated hydroxytoluene. Useful preservatives include, without limitation, benzalkonium chloride, chlorobutanol, thimerosal, phenylmercuric acetate, phenylmercuric nitrate, a stabilized oxy chloro composition and chelants, such as, e.g., DTPA or DTPA-bisamide, calcium DTPA, and CaNaDTPA-bisamide. Tonicity adjustors useful in a pharmaceutical composition include, without limitation, salts such as, e.g., sodium chloride, potassium chloride, mannitol or glycerin and other pharmaceutically acceptable tonicity adjustor. The pharmaceutical composition may be provided as a salt and can be formed with many acids, including but not limited to, hydrochloric, sulfuric, acetic, lactic, tartaric, malic, succinic, etc. Salts tend to be more soluble in aqueous or other protonic solvents than are the corresponding free base forms. It is understood that these and other substances known in the art of pharmacology can be included in a pharmaceutical composition.

[015] In one embodiment, a pharmaceutical composition disclosed herein comprises a therapeutic compound having an anti-pain activity and a pharmaceutically-acceptable adjuvant. An anti-pain activity encompasses a deadening or absence of the sense of pain or nociception without loss of consciousness and includes, without limitation, an analgesic activity, and/or a nociceptive activity. In another embodiment, a pharmaceutical composition disclosed herein comprises a therapeutic compound having an anti-pain activity, a pharmaceutically-acceptable solvent, and a pharmaceutically-acceptable adjuvant. In aspects of this embodiment, a pharmaceutical composition disclosed herein may further comprise a pharmaceutically-acceptable stabilizing agent. In other aspects of this embodiment, a pharmaceutical composition disclosed herein may further comprise a pharmaceutically-acceptable carrier, a pharmaceutically-acceptable component, or both pharmaceutically-acceptable carrier and pharmaceutically-acceptable component.

[044] A therapeutic compound disclosed herein may be a nuclear receptor binding agent. Examples of a suitable nuclear receptor binding agent include, without limitation, a Retinoic Acid Receptor (RAR) binding agent, a Retinoid X Receptor (RXR) binding agent, a Liver X Receptor (LXR) binding agent and a Vitamin D binding agent.

[045] A therapeutic compound disclosed herein may be an anti-hyperlipidemic agent. There are several classes of anti-hyperlipidemic agents (also known as hypolipidemic agents). They may differ in both their impact on the cholesterol profile and adverse effects. For example, some may lower low density lipoprotein (LDL), while others may preferentially increase high density lipoprotein (HDL). Clinically, the choice of an agent will depend on the cholesterol profile of an individual, cardiovascular risk of an individual, and/or the liver and kidney functions of an individual. Examples of a suitable anti-hyperlipidemic agent include, without limitation, a fibrate, a statin, a tocotrienol, a niacin, a bile acid sequestrants (resin), a cholesterol absorption inhibitor, a pancreatic lipase inhibitor, and a sympathomimetic amine.

[046] A therapeutic compound disclosed herein may be a fibrate. Fibrates are a class of amphipathic carboxylic acids with lipid level modifying properties. These therapeutic compounds are used for a range of metabolic disorders. One non-limiting use is as an anti-hyperlipidemic agent where it may lower levels of, e.g., triglycerides and LDL as well as increase levels of HDL, Examples of a suitable fibrate include, without limitation, Bezafibrate, Ciprofibrate, Clofibrate, Gemfibrozil, and Fenofibrate.

[047] A therapeutic compound disclosed herein may be a statin. Statins (or HMG-CoA reductase inhibitors) are a class of therapeutic compounds used to lower LDL and/or cholesterol levels by inhibiting the enzyme HMG-CoA reductase, which plays a central role in the production of cholesterol in the liver. To compensate for the decreased cholesterol availability, synthesis of hepatic LDL receptors is increased, resulting in an increased clearance of LDL particles from the blood. Examples of a suitable statin include, without limitation, Atorvastatin, Fluvastatin, Lovastatin, Pitavastatin, Pravastatin, Rosuvastatin, and Simvastatin.

[048] A therapeutic compound disclosed herein may be a tocotrienol. Tocotrienols are anotehr class of HMG-CoA reductase inhibitors and may be used to lower LDL and/or cholesterol levels by inducing hepatic LDL receptor up-regulation and/or decreasing plasma LDL levels. Examples of a suitable tocotrienol include, without limitation, a γ-tocotrienol and a δ- tocotrienol.

[049] A therapeutic compound disclosed herein may be a niacin. Niacins are a class of therapeutic compounds with lipid level modifying properties. For example, a niacin may lower LDL by selectively inhibiting hepatic diacyglycerol acyltransferase 2, reduce triglyceride synthesis, and VLDL secretion through a receptor HM74 and HM74A or GPR109A. These therapeutic compounds are used for a range of metabolic disorders. One non-limiting use is as an anti-hyperlipidemic agent where it may inhibit the breakdown of fats in adipose tissue. Because a niacin blocks the breakdown of fats, it causes a decrease in free fatty acids in the blood and, as a consequence, decreases the secretion of very-low-density lipoproteins (VLDL) and cholesterol by the liver. By lowering VLDL levels, a niacin may also increase the level of HDL in blood. Examples of a suitable niacin include, without limitation, acipimox, niacin, nicotinamide, and vitamin B3.

[050] A therapeutic compound disclosed herein may be a bile acid sequestrant. Bile acid sequestrants (also known as resins) are a class of therapeutic compounds used to bind certain components of bile in the gastrointestinal tract. They disrupt the enterohepatic circulation of bile acids by sequestering them and preventing their reabsorption from the gut. Bile acid sequestrants are particularly effective for lowering LDL and cholesterol by sequestering the cholesterol-containing bile acids released into the intestine and preventing their reabsorption from the intestine. In addition, a bile acid sequestrant may also raise HDL levels. Examples of a suitable bile acid sequestrant include, without limitation, Cholestyramine, Colesevelam, and Colestipol.

[051] A therapeutic compound disclosed herein may be a cholesterol absorption inhibitor. Cholesterol absorption inhibitors are a class of therapeutic compounds that inhibits the absorption of cholesterol from the intestine. Decreased cholesterol absorption leads to an upregulation of LDL-receptors on the surface of cells and an increased LDL-cholesterol uptake into these cells, thus decreasing levels of LDL in the blood plasma. Examples of a suitable cholesterol absorption inhibitor include, without limitation, Ezetimibe, a phytosterol, a sterol and a stanol.

[052] A therapeutic compound disclosed herein may be a fat absorption inhibitor. Fat absorption inhibitors are a class of therapeutic compounds that inhibits the absorption of fat from the intestine. Decreased fat absorption reduces caloric intake. In one aspect, a fat absorption inhibitor inhibits pancreatic lipase, an enzyme that breaks down triglycerides in the intestine. Examples of a suitable fat absorption inhibitor include, without limitation, Orlistat.

[053] A therapeutic compound disclosed herein may be a sympathomimetic amine. Sympathomimetic amines are a class of therapeutic compounds that mimic the effects of transmitter substances of the sympathetic nervous system such as catecholamines, epinephrine (adrenaline), norepinephrine (noradrenaline), and/or dopamine. A sympathomimetic amine may act as an α-adrenergic agonist, a β-adrenergic agonist, a dopaminergic agonist, a monoamine oxidase (MAO) inhibitor, and a COMT inhibitor. Such therapeutic compounds, among other things, are used to treat cardiac arrest, low blood pressure, or even delay premature labor. Examples of a suitable sympathomimetic amine include, without limitation, Clenbuterol, Salbutamol, ephedrine, pseudoephedrine, methamphetamine, amphetamine, phenylephrine, isoproterenol, dobutamine, methylphenidate, lisdexamfetamine, cathine, cathinone, methcathinone, cocaine, benzylpiperazine (BZP), methylenedioxypyrovalerone (MDPV), 4-methylaminorex, pemoline, phenmetrazine, and propylhexedrine.

[054] A therapeutic compound disclosed herein may be an ester of a therapeutic compound. An ester of a therapeutic compound increases the logP value relative to the same therapeutic compound, but without the ester modification. An ester group may be attached to a therapeutic compound by, e.g., a carboxylic acid or hydroxyl functional group present of the therapeutic compound. An ester of a therapeutic compound may have an increased hydrophobicity, and as such, may be dissolved in a reduced volume of solvent disclosed herein. In some instances, an ester of a therapeutic compound may be combined directly with an adjuvant disclosed herein, thereby eliminating the need of a solvent. An ester of a therapeutic compound may enable the making of a pharmaceutical composition disclosed herein, in situations where a non-esterified form of the same therapeutic compound is otherwise immiscible in a solvent disclosed herein. An ester of a therapeutic compound may still be delivered in a manner that more effectively inhibits a pro-inflammatory response as long as the compound is combined with an adjuvant disclosed herein. In one embodiment, a therapeutic compound may be reacted with ethyl ester in order to form an ethyl ester of the therapeutic compound.

[071] In one embodiment, an adjuvant may be a pharmaceutically-acceptable lipid. A lipid may be broadly defined as a hydrophobic or amphiphilic small molecule. The amphiphilic nature of some lipids allows them to form structures such as vesicles, liposomes, or membranes in an aqueous environment. Non-limiting examples, of lipids include fatty acids, glycerolipids (like monoglycerides, diglycerides, and triglycerides), phospholipids, sphingolipids, sterol lipids, prenol lipids, saccharolipids, and polyketides. A pharmaceutical composition disclosed herein may comprise a lipid such as, e.g. an oil, an oil-based liquid, a fat, a fatty acid, a wax, a fatty acid ester, a fatty acid salt, a fatty alcohol, a glyceride (mono-, di-or triglyceride), a partially hydrolyzed glycerolipid, a phospholipids, a glycol ester, a sucrose ester, a glycerol oleate derivative, a medium chain triglyceride, or a mixture thereof. Other examples of pharmaceutically-acceptable lipids useful as adjuvants are described in, e.g., US 6,923,988, US 6,451,339, US 6,383,471, US 6,294,192, and US 6,267,985, each of which is hereby incorporated by reference in its entirety.

[072] A lipid useful in the pharmaceutical compositions disclosed herein may be a pharmaceutically-acceptable fatty acid. A fatty acid comprises a carboxylic acid with a long unbranched hydrocarbon chain which may be either saturated or unsaturated. Thus arrangement confers a fatty acid with a polar, hydrophilic end, and a nonpolar, hydrophobic end that is insoluble, in water. Most naturally occurring fatty acids have a hydrocarbon chain of an even number of carbon atoms, typically between 4 and 24 carbons, and may be attached to functional groups containing oxygen, halogens, nitrogen, and sulfur. Synthetic or non-natural fatty acids may have a hydrocarbon chain of any number of carbon atoms from between 3 and 40 carbons. Where a double bond exists, there is the possibility of either a cis or a trans geometric isomerism, which significantly affects the molecule's molecular configuration. Cis-doubie bonds cause the fatty acid chain to bend, an effect that is more pronounced the more double bonds there are in a chain.

[073] A lipid useful in the pharmaceutical compositions disclosed herein may be a pharmaceutically-acceptable partially hydrogenated lipid. The process of hydrogenation adds hydrogen atoms to unsaturated lipid, eliminating double bonds and making them into partially or completely saturated lipid. Partial hydrogenation is a chemical rather than enzymatic, that converts a part of cis-isomers into trans-unsaturated lipids instead of hydrogenating them completely. In the first reaction step, one hydrogen is added, with the other, coordinatively unsaturated, carbon being attached to the catalyst. The second step is the addition of hydrogen to the remaining carbon, producing a saturated fatty acid. The first step is reversible, such that the hydrogen is readsorbed on the catalyst and the double bond is re-formed. The intermediate with only one hydrogen added contains no double bond and can freely rotate. Thus, the double bond can re-form as either cis or trans, of which trans is favored, regardless the starting material.

The structure of the phospholipid generally comprises a hydrophobic tail and a hydrophilic head and is amphipathic in nature. Most phospholipids contain a diglyceride, a phosphate group, and a simple organic molecule such as choline; one exception to this rule is sphingomyelin, which is derived from sphingosine instead of glycerol.

[0103] In one embodiment, a pharmaceutically-acceptable stabilizing agent does not comprise a pharmaceutically-acceptable emulsifying agent.

[0104] In another embodiment, a pharmaceutical composition does not comprise a pharmaceutically-acceptable emulsifying agent.

[0105] The pharmaceutical compositions disclosed herein act as a delivery system that enable a therapeutic compound disclosed herein to be more effectively delivered or targeted to a cell type, tissue, organ, or region of the body in a manner that more effectively inhibits a pain response. This inhibition results in an improved treatment of a severe pain. For example, a pharmaceutical composition disclosed herein may facilitate the delivery of a therapeutic compound disclosed herein into macrophages. One possible mechanism that achieves this selective biodistribution is that the pharmaceutical compositions disclosed herein may be designed to take advantage of the activity of chylomicrons. Chylomicrons are relatively large lipoprotein particles having a diameter of 75 nm to 1,200 nm. Comprising triglycerides (85-92%), phospholipids (6-12%), cholesterol (1-3%) and apolipoproteins (1-2%), chylomicrons transport dietary lipids from the intestines to other locations in the body. Chylomicrons are one of the five major groups of lipoproteins, the others being VLDL, IDL, low-density lipoproteins (LDL), high-density lipoproteins (HDL), that enable fats and cholesterol to move within the water-based solution of the bloodstream.

[0106] During digestion, fatty acids and cholesterol undergo processing in the gastrointestinal tract by the action of pancreatic juices including lipases and emulsification with bile salts to generate micelles. These micelles allow the absorption of lipid as free fatty acids by the absorptive cells of the small intestine, known as enterocytes. Once in the enterocytes, triglycerides and cholesterol are assembled into nascent chylomicrons. Nascent chylomicrons are primarily composed of triglycerides (85%) and contain some cholesterol and cholesteryl esters. The main apolipoprotein component is apolipoprotein B-48 (APOB48). These nascent chylomicrons are released by exocytosis from enterocytes into lacteals, lymphatic vessels originating in the villi of the small intestine, and are then secreted into the bloodstream at the thoracic duct's connection with the left subclavian vein.

[0107] While circulating in lymph and blood,-chylomicrons exchange components with HDL. The HDL donates apolipoprotein C-ll (APOC2) and apolipoprotein E (APOE) to the nascent chylomicron and thus converts it to a mature chylomicron (often referred to simply as "chylomicron"). APOC2 is the cofactor for lipoprotein lipase (LPL) activity. Once triglyceride stores are distributed, the chylomicron returns APOC2 to the HDL (but keeps APOE), and, thus, becomes a chylomicron remnant, now only 30-50 nm. APOB48 and APOE are important to identify the chylomicron remnant in the liver for endocytosis and breakdown into lipoproteins (VLDL, LDL and HDL). These lipoproteins are processed and stored by competent cells, including, e.g., hepatocytes, adipocytes and macrophages. Thus, without wishing to be limited by any theory, upon oral administration, a pharmaceutical composition disclosed herein can be processed into micelles while in the gastrointestinal tract, absorbed by enterocytes and assembled into nascent chylomicrons, remain associated with chylomicron remnants taken up by the liver, and ultimately loaded into macrophages which are present in tissues experiencing pain.

[0108] As another example, a pharmaceutical composition disclosed herein may facilitate the delivery of a therapeutic compound disclosed herein into dentritic cells. One possible mechanism to achieve selective biodistribution of the pharmaceutical compositions disclosed herein may be to take advantage of the endocytotic/phagocytotic activity of dentritic cells. Dendritic cells are immune cells forming part of the mammalian immune system. The main function of dendritic cells is to process antigen material and present it on the surface to other cells of the immune system. Thus, dendritic cells function as antigen-presenting cells that act as messengers between innate and adaptive immunity. Dendritic cells are present in tissues in contact with the external environment, such as, e.g., the skin (where there is a specialized dendritic cell type called Langerhans cells) and the inner lining of the nose, lungs, stomach and intestines. These cells can also be found in an immature state in the blood. Once activated, they migrate to the lymph nodes where they interact with T cells and B cells to initiate and shape the adaptive immune response. Dendritic cells are known to endocytose and phagocytose lipid particles as part of their environmental monitoring and antigen presentation processes. Without wishing to be limited by any theory, upon topical or inhalatory administration, a pharmaceutical composition disclosed herein can penetrate into the skin or inner lining of the nose, lungs, stomach and intestines, be endocytosed/phagocytosed by dentritic cells, and ultimately loaded into T cells and/or B cells which are present in tissues experiencing pain.

[0151] A solid or semi-solid formulation disclosed herein takes advantage of the different melting point temperatures of the various adjuvants like fatty acids. Formation of a solid or semi-solid dosage form can be by modifying the respective concentrations of the fatty acids comprising a pharmaceutical composition disclosed herein. For example, linolenic acid has a melting point temperature (Tm) of about -11°C, linoleic acid has a Tm of about -5°C, oleic acid has a Tm of about 16°C, palmitic acid has a Tm of about 61-62°C, and Stearic acid has a Tm of about 67-72°C. Increasing the proportion(s) of palmitic, stearic or oleic acid would increase the overall melting temperature of a composition, while, conversely, increasing the proportion(s) of linoleic and linolenic acid would decrease the melting temperature of a composition. Thus, by controlling the types and amounts of the adjuvant components added, a pharmaceutical composition disclosed herein can be made that is substantially solid or semi-solid at room temperature, but melts when it is ingested, and reaches body temperature. The resulting melted composition readily forms micelles which are absorbed by the intestine, assembled into chylomicrons, and ultimately absorbed by macrophages. The solid dosage form may be a powder, granule, tablet, capsule or suppository.

[0152] In an embodiment, a pharmaceutical composition disclosed herein is solid at room temperature. In aspects of this embodiment, a pharmaceutical composition disclosed herein may be formulated to be a solid at a temperature of, e.g., about 35°C or lower, about 33°C or lower, about 31 °C or lower, about 29°C or lower, about 27°C or lower, about 25°C or lower, about 23°C or lower, about 21°C or lower, about 19°C or lower, about 17°C or lower, about 15°C or lower, about 12°C or lower, about 10°C or lower, about 8°C or lower, about 6°C or lower, about 4°C or lower, or about 0°C or lower.

[0153] In other aspects of this embodiment, a pharmaceutical composition disclosed has a melting point temperature of, e.g., 5 °C or higher, 10 °C or higher, 15 °C or higher, 22°C or higher, 23°C or higher, 24°C or higher, 25°C or higher, 26°C or higher, 27°C or higher, 28°C or higher, 29°C or higher, 30°C or higher, 31 °C or higher, 32°C or higher, 33°C or higher, 34°C or higher, or 35°C or higher. In other aspects of this embodiment, a pharmaceutical composition disclosed has a melting point temperature in the range of, e.g., about 5°C to about 24°C, about 10°C to about 24°C. about 22°C to about 24°C, about 23°C to about 25°C, about 24°C to about 26°C, about 25°C to about 27°C, about 26°C to about 28°C, about 27°C to about 29°C, about 28°C to about 30°C, about 29°C to about 31 °C, about 30°C to about 32°C, about 31 °C to about 33°C, about 32°C to about 34°C, or about 33°C to about 35°C. In other aspects of this embodiment, a pharmaceutical composition disclosed has a melting point temperature in the range of, e.g., about 22°C to about 26°C, about 24°C to about 28°C, about 26°C to about 30°C, about 28°C to about 32°C, or about 30°C to about 34°C.

[0154] Aspects of the present specification disclose, in part, a method of treating an individual with a severe pain condition. In one embodiment, the method comprises the step of administering to an individual in need thereof a pharmaceutical composition disclosed herein, wherein administration reduces a symptom associated with the severe pain, thereby treating the individual.

[0155] Aspects of the present specification disclose, in part, treating an individual suffering from a severe pain condition. As used herein, the term "treating,” refers to reducing or eliminating in an individual a clinical symptom of a severe pain condition; or delaying or preventing in an individual the onset of a clinical symptom of a severe pain condition. For example, the term “treating” can mean reducing a symptom of a condition characterized by a severe pain condition by, e.g., at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90% at least 95%, or at least 100%. The actual symptoms associated with a severe pain condition are well known and can be determined by a person of ordinary skill in the art by taking into account factors, including, without limitation, the location of the severe pain condition, the cause of the severe pain condition, the severity of the severe pain condition, and/or the tissue or organ affected by the severe pain condition. Those of skill in the art will know the appropriate symptoms or indicators associated with a specific type of severe pain condition and will know how to determine if an individual is a candidate for treatment as disclosed herein.

[0156] Pain may be measured using one or more pain thresholds. Pain thresholds are measured by gradually increasing the intensity of a stimulus such as electric current or heat applied to the body. The pain perception threshold is the point at which the stimulus begins to hurt, and the pain tolerance threshold is reached when the individual acts to stop the pain.

[0157] Pain may be measured using one or more pain scale questionnaires. Although a self-reported questionaire by an individual suffering from a severe pain condition tend to be the most reliable measure of pain, reports from health care professionals may also be used. A number of pain measurement scales have been developed including, without limitation, Alder Hey Triage Pain Score, Behavioral Pain Scale (BPS), Brief Pain Inventory (BPI), Checklist of Nonverbal Pain Indicators (CNPI), Critical-Care Pain Observation Tool (CPOT), COMFORT scale, Dallas Pain Questionnaire, Descriptor differential scale (DDS), Disease-Specific Pain Scale (DSPI ), Dolorimeter Pain Index (DPI), Faces Pain Scale - Revised (FPS-R), Face Legs Activity Cry Consolability scale, Lequesne algofunctional index, Original index, McGill Pain Questionnaire (MPQ), Multidimensional Pain Inventory (MPI), Neck Pain and Disability Scale -NPAD, Numerical 11 point box (BS-11), Numeric Rating Scale (NRS-11), Pediatric Pain Questionnaire (PPQ), Roland-Morris Back Pain Questionnaire, Visual analog scale (VAS), and Wong-Baker FACES Pain Rating Scale. As one example, a NRS-11 scale is an 11-point scale for patient self-reporting that ranks the pain being experienced on a scale of 0 to 10, with 0 being no pain at all, 1-3 being mild pain that interferes little with activities of daily life, 4-6 being moderate pain that interferes significantly with activities of daily life, and 7-10 being severe pain that completely interferes with activities of daily life. Quality can be established by having the individual complete the McGill Pain Questionnaire indicating which words best describe their pain.

[0158] Severe pain condition symptoms include, without limitation, a coldness, a numbness, an itching, a paresthesias, an electric shock sensation, a burning sensation, an ice-burn sensation, dysesthesia, allodynia, hyperalgesia, hyperpathia, a somatic pain sensation, and a visceral pain sensation. The actual symptoms associated with a severe pain condition are well known and can be determined by a person of ordinary skill in the art by taking into account factors, including, without limitation, the location of the severe pain, the cause of the severe pain, the severity of the severe pain, the tissue or organ affected, and the associated disorder.

[0159] A pharmaceutical composition disclosed herein are useful to treat severe pain. Pain is any unpleasant sensory and/or emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Pain may occur in varying degrees of severity and is usually a consequence of an injury, a disease, or an emotional disorder, although the underlying cause may or may not be apparent to a healthcare provider. A severe pain is one where the severity of the pain response significantly interferes or prevents an individual from performing one or more activities of daily life. An activity of daily life (ADL) is an activity an individual normally does such as feeding, bathing, dressing, grooming, work, homemaking, and leisure. ADLs may be categorized based on whether the activity is a basic, an instrumental, or an occupational one. Basic ADLs (BADLs) comprise self-care tasks, including, e.g., personal hygiene and grooming, dressing and undressing, self feeding, functional transfers (getting into and out of bed or wheelchair, getting onto or off toilet, etc.), bowel and bladder management, and ambulation (walking with or without use of an assistive device (walker, cane, or crutches) or using a wheelchair). Instrumental ADLs (lADLs) are not necessary for fundamental functioning, but let an individual live independently in a community. lADLs include, e.g., performing housework, taking medications as prescribed, managing money, shopping for groceries or clothing, using communication devices, using technology, using transportation within the community. Occupational ADLs (OADLs) are generally optional in nature and may be delegated to others. OADLs include, e.g., caring of others (including selecting and supervising caregivers), caring of pets, child rearing, using of communication devices, community mobility, financial management, health management and maintenance, meal preparation and cleanup, and safety procedures and emergency responses.

[0160] As used herein, the term “severe pain” comprises any acute, subacute, chronic nociceptive, pathological pain, or psychological pain. In aspects of this embodiment, a severe pain is not an inflammatory pain or a pain whose primary origin is due to an inflammatory response.

[0161] A severe pain condition may be classified according to duration and pattern of occurrence, such as, e.g., acute pain, subacute pain, and chronic pain. Acute pain is an organic pain state that is typically transitory and of sudden onset, lasting only until the noxious stimulus is removed and/or the underlying damage or pathology has healed. Chronic pain is an organic pain state that is persistent and extends beyond the expected period of healing and may be present continuously or intermediately. Subacute pain is an organic pain state that refers to a pain that is somewhere in between acute pain and chronic pain. Although somewhat arbitrary, the distinction between acute, subacute, and chronic pain may be defined based on the interval of time from onset. Thus, an acute pain is one that lasts less then one month, a subacute pain is one that lasts from one to six months, and a chronic pain is one that lasts six months or more.

[0162] A severe pain condition may also be classified as 1) a nociceptive pain; 2) a pathological pain; and 3) an inflammatory pain.

[0163] In one embodiment, a severe pain condition comprises a nociceptive pain. Nociceptive pain is a severe pain condition where an organic pain state is caused by a noxious insult or injury of peripheral nerve fibers that respond only to stimuli approaching or exceeding harmful intensity (nociceptors), and is commonly described as an aching pain. This type of pain is associated with damage to non-neural tissue, such as skin, muscles, visceral organs, joints, tendons, or bones, and is represented by a normally functioning somatosensory nervous system. Nociceptive pain may be classified according to the mode of noxious stimulation, such as, e.g., thermal pain, mechanical pain, and chemical pain, or according to the location of the pain, such as, e.g., somatic pain or visceral pain.

[0164] In one embodiment, a severe pain condition comprises a somatic pain. Somatic pain is a nociceptive pain that originates from ligaments, tendons, bones, blood vessels, and even nerves themselves. It is detected with somatic nociceptors. The scarcity of pain receptors in these areas produces a dull, poorly-localized pain of longer duration than cutaneous pain. Non-limiting examples of somatic pain include 1) excessive muscle tension can be caused, for example, by a sprain or a strain; 2) repetitive motion disorders can result from overuse of the hands, wrists, elbows, shoulders, neck, back, hips, knees, feet, legs, or ankles; 3) muscle disorders causing somatic pain include, for example, a polymyositis, a dermatomyositis, a lupus, a fibromyalgia, a polymyalgia rheumatica, and a rhabdomyolysis; 4) myalgia including, e.g., muscle pain caused by overuse, over-stretching, viral infection, metabolic myopathy, a nutritional deficiency, or chronic fatigue syndrome; 5) infections including, e.g., an abscess, a trichinosis, an influenza, a Lyme disease, a malaria, a Rocky Mountain spotted fever, Avian influenza, the common cold, community-acquired pneumonia, meningitis, monkeypox, Severe Acute Respiratory Syndrome, toxic shock syndrome, trichinosis, typhoid fever, and upper respiratory tract infection; and 6) drugs including, e.g., cocaine, a statin for lowering cholesterol (such as atorvastatin, simvastatin, and lovastatin), and an ACE inhibitor for lowering blood pressure (such as enalapril and captopril). Somatic pain may be classified as a superficial somatic pain or a deep somatic pain. Superficial somatic pain is initiated by activation of nociceptors in the skin or other superficial tissue, and is sharp, well-defined and clearly located. Examples of injuries that produce superficial somatic pain include minor wounds and minor (first degree) burns. Deep somatic pain is initiated by stimulation of nociceptors in ligaments, tendons, bones, blood vessels, fasciae and muscles, and is dull, aching, poorly localized pain. Examples include sprains and broken bones.

[0165] In one embodiment, a severe pain condition comprises a visceral pain. Visceral pain is a nociceptive pain that is initiated by stimulation of nociceptors in the body's organs and internal cavities typically caused by stretching or ischemia. Visceral pain is a diffuse, poorly localized pain and may be described as aching pain, sickening pain, dull pain, squeezing pain, and/or deep pain, and it may be accompanied by nausea and vomiting. Visceral pain is extremely difficult to localize, and several injuries to visceral tissue may exhibit "referred" pain, where the sensation is localized to an area completely unrelated to the site of injury. The even greater scarcity of nociceptors in these areas produces pain that is usually more aching and of a longer duration than somatic pain. Non-limiting examples of somatic pain include 1) functional visceral pain including, e.g., an irritable bowel syndrome and a chronic functional abdominal pain (CFAP), a functional constipation and a functional dyspepsia, a non-cardiac chest pain (NCCP) and a chronic abdominal pain; 2) chronic gastrointestinal inflammation including, e.g., a gastritis, an inflammatory bowel disease, like, e.g., a Crohn's disease, an ulcerative colitis, a microscopic colitis, a diverticulitis and a gastroenteritis; an interstitial cystitis; an intestinal ischemia; a cholecystitis; an appendicitis; a gastroesophageal reflux; an ulcer, a nephrolithiasis, an urinary tract infection, a pancreatitis and a hernia; 3) autoimmune pain including, e.g., a sarcoidosis and a vasculitis; 4) organic visceral pain including, e.g., pain resulting from a traumatic, inflammatory or degenerative lesion of the gut or produced by a tumor impinging on sensory innervation; and 5) treatment-induced visceral pain including, e.g., a pain attendant to chemotherapy therapy or a pain attendant to radiation therapy.

[0166] In one embodiment, a severe pain condition comprises a pathological pain. Damage A pathological pain is a severe pain condition where an organic pain state caused by disease or damage to any part of the nervous system or by caused by an abnormal functioning of the nervous system. This type of pain is associated with damage to neural tissue and an abnormally functioning somatosensory nervous system, rather than stimulation of pain receptors. Non-limiting examples of a pathological pain include neuropathic pain and dysfunctional pain.

[0167] In one embodiment, a severe pain condition comprises a neuropathic pain. Damage Neuropathic pain is a pathological pain where an organic pain state is caused by damage or disease of the somatosensory nervous system, resulting in abnormal sensory firing from the peripheral nervous system, central nervous systems, or both. Neuropathic pain may involve spontaneous or evoked pain, and may have continuous and/or episodic (paroxysmal) components. Neuropathic pain may be associated with dysesthesia (abnormal pain responses), such as, e.g., allodynia (a painful response to a stimulus that normally is not painful), hyperalgesia (an accentuated response to a painful stimulus that usually causes only a mild discomfort), and hyperpathia (where a short discomfort becomes a prolonged severe pain). Painful sensations can be described as a coldness, numbness, itching, paresthesias (tingling or "pins and needles" sensation), an electric shock, and a burning or ice-burn pain. Non-limiting examples of a neuropathic pain include central neuropathic pain, peripheral neuropathic pain, and deafferentation pain.

[0168] In one embodiment, a severe pain condition comprises a central neuropathic pain. Damage or disease affecting nerves of the central nervous system is referred to as a central neuropathic pain. Typically, the damage or disease occurs as cerebral lesions, predominantly thalamic but may involve suprathalamic and infrathalamic regions. Generally, the onset of central neuropathic pain is usually delayed after the occurrence of the initial episode that results in damage to the central nervous system; onset of pain may occur during the phase of recovery from neurologic deficits. Central neuropathic pain may be present in post-stroke conditions including, e.g., thalamic infarction, brainstem infarction, or subarachnoid hemorrhage, cerebral venous thrombosis, cerebral tumors compressing the thalamus or brainstem, cerebral abscesses compressing the thalamus or brainstem, traumatic brain injury, post-surgical pain following brain or spine surgery, complications following brain surgery including thalamotomy for movement disorders, multiple sclerosis, and Parkinson disease, spinal cord injury, complications following spinal surgery including anterolateral cordotomy and commissural myelotomy, ischemic lesions including anterior spinal artery syndrome and Wallenberg syndrome, syringomyelia, radiation myelopathy, HIV myelopathy.

[0169] In one embodiment, a severe pain condition comprises a peripheral neuropathic pain. Damage or disease affecting sensory, motor, and/or autonomic nerves of the peripheral nervous system is referred to as a peripheral neuropathic pain. Peripheral neuropathic pain occurs when peripheral nerves fail to carry information to and from the brain and spinal cord, resulting in pain, loss of sensation, or inability to control muscles. In some cases, the failure of nerves that control blood vessels, intestines, and other organs results in abnormal blood pressure, digestion problems, and loss of other basic body processes. Symptoms also depend on whether the condition affects the whole body or just one nerve. Risk factors for neuropathy include diabetes, heavy alcohol use, exposure to certain chemicals and drugs, prolonged pressure on a nerve. Some people have a hereditary predisposition for peripheral neuropathy. The four cardinal patterns of peripheral neuropathic pain are mononeuropathy, mononeuropathic multiplex, polyneuropathy, and autonomic neuropathy.

[0170] In one embodiment, a severe pain condition comprises a mononeuropathic. A mononeuropathy is a peripheral neuropathy involving functional loss or pathological change affecting a single nerve or nerve group. Mononeuropathy is most often caused by damage to a local area resulting from injury or trauma, although occasionally systemic disorders may cause isolated nerve damage. The usual causes are direct trauma, prolonged pressure on the nerve, and compression of the nerve by swelling or injury to nearby body structures. The damage includes destruction of the myelin sheath (covering) of the nerve or of part of the nerve cell (the axon). This damage slows or prevents conduction of impulses through the nerve. Mononeuropathy may involve any part of the body. Mononeuropathic pain is associated with, e.g., a sciatic nerve dysfunction, a common peroneal nerve dysfunction, a radial nerve dysfunction, an ulnar nerve dysfunction, a cranial mononeuropathy VI, a cranial mononeuropathy VII, a cranial mononeuropathy III (compression type), a cranial mononeuropathy III (diabetic type), an axillary nerve dysfunction, a carpal tunnel syndrome, a femoral nerve dysfunction, a tibial nerve dysfunction, a Bell's palsy, a thoracic outlet syndrome, a carpal tunnel syndrome or other focal entrapment neuropathy, and a sixth (abducent) nerve palsy [0171] In one embodiment, a severe pain condition comprises a mononeuropathic multiplex. A mononeuropathic multiplex is a peripheral neuropathy involving functional loss or pathological change that sequentially or simultaneously affects several non-contiguous nerves in an asymmetric manner. A neuropathic pain based on mononeuropathy multiplex may develop over days to years and typically presents with acute or subacute loss of sensory and motor function of individual nerves. The pattern of involvement is asymmetric; however, as the disease progresses deficit(s) becomes more confluent and symmetrical, making it difficult to differentiate from polyneuropathy. Mononeuropathic multiplex may also cause pain characterized as deep, aching pain that is worse at night, and frequently present in the lower back, hip, or leg. Mononeuropathic multiplex may also cause pain characterized as acute, unilateral, severe limb pain followed by anterior muscle weakness and loss of knee reflex. Mononeuropathic multiplex pain is associated with, e.g., diabetes mellitus, infections, such as, e.g., leprosy, lyme disease, HIV, and toxicity.

[0172] In one embodiment, a severe pain condition comprises a polyneuropathy. A polyneuropathy is a peripheral neuropathy involving functional loss or pathological change affecting multiple nerves throughout the body in a symmetric manner. A polyneuropathy may be acute and appear without warning, or chronic and develop gradually over a longer period of time. Many polyneuropathies have both motor and sensory involvement, and some also involve dysfunction of the autonomic nervous system. These disorders are often symmetrical, and usually due to various systematic illnesses and disease processes that affect the peripheral nervous system in its entirety. A polyneuropathy frequently affect the feet and hands, causing weakness, loss of sensation, pins-and-needle sensations or burning pain. Polyneuropathies can be classified in different ways, such as by cause, by speed of progression, or by the parts of the body involved. Classes of polyneuropathy are also distinguished by which part of the nerve cell is mainly affected: the axon, the myelin sheath, or the cell body.

[0173] In one embodiment, a severe pain condition comprises a distal axonopathy. Distal axonopathy, or "dying-back neuropathy”, is the result of some metabolic or toxic derangement of a neuron. They may be caused by metabolic diseases such as diabetes, renal failure, deficiency syndromes such as malnutrition and alcoholism, or the effects of toxins or drugs such as chemotherapy. The most common cause of distal axonopathy is diabetes, and the most common distal axonopathy is diabetic neuropathy. They can be divided according to the type of axon affected: large-fiber, small-fiber, or both. The most distal portions of axons are usually the first to degenerate, and axonal atrophy advances slowly towards the nerve's cell body. If the cause is removed, regeneration is possible, though the prognosis depends on the duration and severity of the stimulus. People with distal axonopathies usually present with sensorimotor disturbances that have a symmetrical "stocking and glove" distribution. Deep tendon reflexes and autonomic nervous system functions are also lost or diminished in affected areas.

[0174] In one embodiment, a severe pain condition comprises a myelinopathy. Myelinopathy, or "demyelinating polyneuropathy", is due to a loss of myelin (or of the Schwann cells that make and contain it). This demyelination leaves the axon intact, but slows down or completely blocks the conduction of action potentials through the axon of the nerve cell. The most common cause is acute inflammatory demyelinating polyneuropathy (AIDP, the most common form of Guillain-Barre syndrome), though other causes include chronic inflammatory demyelinating polyneuropathy (CIDP), genetic metabolic disorders (e g., leukodystrophy), and toxins.

[0175] In one embodiment, a severe pain condition comprises a neuronopathy. Neuronopathy is the result of destruction of peripheral nervous system neurons. They may be caused by motor neuron diseases, sensory neuronopathies (e.g., Herpes zoster), toxins or autonomic dysfunction. Neurotoxins may cause neuronopathies, such as the chemotherapy agent vincristine. A person with neuronopathy may present in different ways, depending on the cause, the way it affects the nerve cells, and the type of nerve cell that is most affected.

[0176] There are numerous conditions that can cause polyneuropathy. Peripheral neuropathic pain include, without limitation, neuropathies associated with systemic disease like diabetic neuropathy, neuropathies associated with metabolic conditions like alcoholic neuropathy and burning feet syndrome, neuropathies associated with viral infections like herpes zoster and HIV, neuropathies associated with nutritional deficiencies, neuropathies associated with toxins, neuropathies associated with tumor compression, neuropathies associated with remote manifestations of malignancies, neuropathies associated with drugs like chemotherapy, neuropathies associated with radiation, neuropathies associated with immune mediated disorders, and neuropathies associated with physical trauma to a nerve trunk. Polyneuropathic pain, includes, without limitation, post-polio syndrome, postmastectomy syndrome, diabetic neuropathy, alcohol neuropathy, amyloid, toxins, AIDS, hypothyroidism, uremia, vitamin deficiencies, chemotherapy-induced pain, 2',3'-didexoycytidine (ddC) treatment, Guillain-Barre syndrome or Fabry's disease.

[0177] In one embodiment, a severe pain condition comprises an autonomic neuropathy. An autonomic neuropathy is a peripheral neuropathy involving functional loss or pathological change affecting the nonvoluntary, non-sensory nervous system (i.e., the autonomic nervous system). Autonomic neuropathy is a form of polyneuropathy which affects mostly the internal organs such as the bladder, muscles, the cardiovascular system, the digestive tract, and the genital organs.

[0178] Peripheral neuropathic pain may be present in systemic diseases, metabolic disorders, nutrient disorders, drug-induced disorders, traumatic injury, traumatic and entrapment syndromes, post-surgical pain surgery, complications following surgery, HIV sensory neuropathy, demyelinating polyradiculoneuropathy, postherpetic neuralgia, nerve root avulsions, cranial neuralgias like trigeminal neuralgia, neuropathic cancer pain, compression of peripheral nerves, nerve plexuses, and nerve roots, paraneoplastic peripheral neuropathy, ganglionopathy, complication of cancer therapies like chemotherapy, radiation, and surgery, and complex regional pain syndrome like Type 1 and Type 2.

[0179] In one embodiment, a severe pain condition comprises a neuralgia. A neuralgia is a peripheral neuropathic pain that radiates along the course of one or more specific nerves usually without any demonstrable pathological change in the nerve structure. The affected nerves are responsible for sensing touch, temperature and pressure. Simple stimuli such as eating, talking, washing the face, or any light touch or sensation can trigger an attack (even the sensation of a gentle breeze). The attacks can occur in clusters or as an isolated attack. Generally, a neuralgia causes short episodes of excruciating pain, usually for less than two minutes. However, in the atypical forms of neuralgia, the pain can also present as merely aching to severe pain and last for extended periods. Symptoms include sharp, stabbing pain or constant, burning pain located anywhere, usually on or near the surface of the body, in the same location for each episode; pain along the path of a specific nerve; impaired function of affected body part due to pain, or muscle weakness due to concomitant motor nerve damage; increased sensitivity of the skin or numbness of the affected skin area; and any touch or pressure is interpreted as pain. Movement may also be painful. A neuralgia, includes, without limitation, a trigeminal neuralgia, a glossopharyngeal neuralgia, a post-herpetic neuralgia (caused by, e.g., herpesvirus, syphilis and Lyme disease), a carpal tunnel syndrome, a meralgia paresthetica, a sciatica and an atypical facial pain.

[0180] In one embodiment, a severe pain condition comprises a Complex Regional Pain Syndrome (CRPS). A CRPS is a neuropathy resulting from sympathetically-maintained pain. Although unknown, mechanisms probably involve abnormal sympathetic-somatic nerve connections (ephapses), local inflammatory changes, and changes in the spinal cord. CRPS presents in two forms. CRPS 1 (reflex sympathetic dystrophy syndrome) is a chronic nerve disorder that occurs most often in the arms or legs after a minor or major injury. CRPS 1 is associated with severe pain; changes in the nails, bone, and skin; and an increased sensitivity to touch in the affected limb. CRPS 2 (causalgia) is caused by an identified injury to the nerve and results in a syndrome of sustained burning pain, allodynia, and hyperpathia after a traumatic nerve lesion, often combined with vasomotor and sudomotor dysfunction and later trophic changes.

[0181] In one embodiment, a severe pain condition comprises a referred pain. Referred pain arises from pain localized to an area separate from the site of pain stimulation. Often, referred pain arises when a nerve is compressed or damaged at or near its origin. In this circumstance, the sensation of pain will generally be felt in the territory that the nerve serves, even though the damage originates elsewhere. A common example occurs in intervertebral disc herniation, in which a nerve root arising from the spinal cord is compressed by adjacent disc material. Although pain may arise from the damaged disc itself, pain will also be felt in the region served by the compressed nerve (for example, the thigh, knee, or foot). Relieving the pressure on the nerve root may ameliorate the referred pain, provided that permanent nerve damage has not occurred. Myocardial ischaemia (the loss of blood flow to a part of the heart muscle tissue) is possibly the best known example of referred pain; the sensation can occur in the upper chest as a restricted feeling, or as an ache in the left shoulder, arm or even hand.

[0182] In one embodiment, a severe pain condition comprises a deafferentation pain. Damage or disease affecting peripheral or central afferent neural activity is referred to as a deafferentation pain. Deafferentation pain is due to partial or complete loss of the sensory input from a portion of the body, and can be caused by interruption of either peripheral sensory fibres or nerves from the central nervous system. The mechanism underlying this type of pain is unknown but may involve sensitization of central neurons, with lower activation thresholds and expansion of receptive fields. A deafferentation pain syndrome, includes, without limitation, a phantom pain, a brain injury, a spinal cord injury, a lumbar radiculopathy, a post-stroke pain, a paraplegia, avulsion of the brachial plexus or other types of lesions of peripheral nerves, a pathology of the central nervous system.

[0183] In one embodiment, a severe pain condition comprises a dysfunctional pain. Dysfunctional pain is a pathological pain where an organic pain state is caused by abnormal function of the somatosensory nervous system, but which are not initiated by an identifiable lesion of any part of the nervous system. Similar to neuropathic pain, dysfunctional pain is commonly described as a burning pain, a coldness, an electric shock, a "pins and needles" sensation, numbness and itching.

[0184] In one embodiment, a severe pain condition comprises a headache. A severe pain condition may be a headache (medically known as cephalgia) is a condition of mild to severe pain in the head; sometimes neck or upper back pain may also be interpreted as a headache. It may indicate an underlying local or systemic disease or be a disorder in itself. A headache includes, without limitation, a muscular/myogenic headache, a vascular headache, a traction headache, inflammatory headache, a chronic sinusitis headache, a hormone headache, a rebound headache, an organic headache, and an ictal headache.

[0185] In one embodiment, a severe pain condition comprises a muscular/myogenic headache. Muscular/myogenic headaches appear to involve the tightening or tensing of facial and neck muscles; they may radiate to the forehead. Tension headache is the most common form of myogenic headache. A tension headache is a condition involving pain or discomfort in the head, scalp, or neck, usually associated with muscle tightness in these areas. Tension headaches result from the contraction of neck and scalp muscles. One cause of this muscle contraction is a response to stress, depression or anxiety. Any activity that causes the head to be held in one position for a long time without moving can cause a headache. Such activities include typing or use of computers, fine work with the hands, and use of a microscope. Sleeping in a cold room or sleeping with the neck in an abnormal position may also trigger this type of headache. A tension-type headache, includes, without limitation, an episodic tension headache and a chronic tension headache.

[0186] In one embodiment, a severe pain condition comprises a vascular headache. The most common type of vascular headache is migraine. Other kinds of vascular headaches include cluster headaches, which cause repeated episodes of intense pain, and headaches resulting from high blood pressure.

[0187] In one embodiment, a severe pain condition comprises a migraine headache. A migraine is a heterogeneous disorder that generally involves recurring headaches. Migraines are different from other headaches because they occur with other symptoms, such as, e.g., nausea, vomiting, or sensitivity to light. In most people, a throbbing pain is felt only on one side of the head. Clinical features such as type of aura symptoms, presence of prodromes, or associated symptoms such as vertigo, may be seen in subgroups of patients with different underlying pathophysiological and genetic mechanisms. A migraine headache, includes, without limitation, a migraine without aura (common migraine), a migraine with aura (classic migraine), a menstrual migraine, a migraine equivalent (acephalic headache), a complicated migraine, an abdominal migraine and a mixed tension migraine.

[0188] In one embodiment, a severe pain condition comprises a cluster headache. Cluster headaches affect one side of the head (unilateral) and may be associated with tearing of the eyes and nasal congestion. They occurs in clusters, happening repeatedly every day at the same time for several weeks and then remitting.

[0189] In one embodiment, a severe pain condition comprises a sinusitis headache. Sinusitis is inflammation, either bacterial, fungal, viral, allergic or autoimmune, of the paranasal sinuses. Chronic sinusitis is one of the most common complications of the common cold. Symptoms include: Nasal congestion; facial pain; headache; fever; general malaise; thick green or yellow discharge; feeling of facial 'fullness' worsening on bending over. In a small number of cases, chronic maxillary sinusitis can also be brought on by the spreading of bacteria from a dental infection. Chronic hyperplastic eosinophilic sinusitis is a noninfective form of chronic sinusitis.

[0190] In one embodiment, a severe pain condition comprises a traction headache. Traction and inflammatory headaches are usually symptoms of other disorders, ranging from stroke to sinus infection.

[0191] In one embodiment, a severe pain condition comprises a rebound headache. Rebound headaches, also known as medication overuse headaches, occur when medication is taken too frequently to relieve headache. Rebound headaches frequently occur daily and can be very painful.

[0192] In one embodiment, a severe pain condition comprises a ictal headache. Ictal headaches are headaches associated with seizure activity.

[0193] In one embodiment, a severe pain condition comprises a psychogenic pain. Psychogenic pain, also called psychalgia or somatoform pain, is pain caused, increased, or prolonged by mental, emotional, or behavioral factors. Headache, back pain, and stomach pain are sometimes diagnosed as psychogenic. Sufferers are often stigmatized, because both medical professionals and the general public tend to think that pain from a psychological source is not "real". However, specialists consider that it is no less actual or hurtful than pain from any other source. Individuals with long term pain frequently display psychological disturbance.

[0194] In one embodiment, a severe pain condition comprises an inflammatory pain. An inflammatory pain is a severe pain condition where an organic pain state is caused by the release of mediators at a site of tissue inflammation which activate and sensitize the nociceptive pain pathway. This type of pain is associated with any tissue damage caused by a chronic inflammatory response. Inflammatory pain may be associate with an arthritic disorder, an autoimmune disease, a connective tissue disorder, an injury, an infection, and a neuritis.

[0195] In one embodiment, a severe pain condition does not comprise an inflammatory pain.

[0196] In one embodiment, a severe pain condition is not caused by an inflammatory response.

[0197] A pharmaceutical composition disclosed herein is administered to an individual. An individual is typically a human being.

EXAMPLES

[0212] The following non-limiting examples are provided for illustrative purposes only in order to facilitate a more complete understanding of representative embodiments now contemplated. These examples should not be construed to limit any of the embodiments described in the present specification, including those pertaining to the compounds, alcohols, lipids, pharmaceutical compositions, methods of preparing pharmaceutical compositions, or methods or uses of treating a severe pain condition.

Example 1

Liquid Formulations of Pharmaceutical Composition [0213] This example illustrates how to make a pharmaceutical, composition as disclosed herein as a liquid formulation.

[0214] Initially, 2,400 mg of ibuprofen was contacted directly with 2.0 mL of rapeseed oil in an attempt to dissolve a therapeutic compound directly into an adjuvant at a concentration of 1,200 mg/mL. However, ibuprofen remained insoluble in the oil and did not dissolve to substantially measureable degree.

Ibuprofen remained insolubility even if the mixture was mixed by vortexing for 20 seconds, the contacting was done at 20°C or 37°C, and/or the mixture was allowed to incubate for 24 hours at 20°C or 37°C. The insolubility of ibuprofen in rapeseed oil was surprising given that ibuprofen has a logP value of 3.6; such a high logP value is indicative of a compound that would readily soluble in an adjuvant like oil.

[0215] Since, it was not possible to dissolve ibuprofen directly into oil, despite its high logP value, it was next tried to dissolve a therapeutic drug in a solvent to first create a solution comprising the compound. As a first step, experiments were conducted to the miscibility of. a solvent in an adjuvant like oil in the absence of a therapeutic compound. In these experiments 0.5 mL ethanol was contacted with ten different volumes of rapeseed oil (Table 1). Each mixture was tested at 22°C and at 37°C in which the ethanol and oil were initially heated in a water bath before being mixed together. Mixing was attempted by vortex mixing for 20 seconds, and the containers were allowed to settle before visual assessment, either immediately, or after 24 hours. Each mixture was evaluated to determine whether or not the ethanol and rapeseed oil form immiscible layers, or a homogeneous mixture. The results are summarized in Table 1. Mixtures comprising solventadjuvant ratios of 1:1, 1:2, 1:3, 1:4, 1:5, and 1:6 formed immiscible layers at either 22°C or at 37°C, either immediately or after 24 hours of incubation, indicating that the ethanol and oil did not mix well at these ratios. However, in solventadjuvant ratios above 1:7 a homogeneous mixture was formed under all conditions tested.

[0216] Once the appropriate ratios of alcohol and lipid necessary to form a homogenous mixture were determined, it was next determined whether contacting a therapeutic compound first in a solvent before contacting with an adjuvant would result in the compound dissolving in the solvents. To conduct these experiments, either 1,000 mg or 1,200 mg of ibuprofen was dissolved into 0.5 mL of ethanol. The resulting alcohol solution was then contacted with rapeseed oil at two different solventadjuvant ratios (1:2 and 1:9). Each mixture was tested at 20°C and at 37°C in which the ethanol solution and oil were initially heated in a water bath before being mixed together. Mixing was attempted by vortex mixing for 20 seconds, and the containers were allowed to settle before visual assessment, either immediately, or after 24 hours. Each mixture was evaluated to determine whether or not the ethanol solution and rapeseed oil form immiscible layers, or a homogeneous mixture. The results are summarized in Table 2. In contrast to the situation in the absence of a therapeutic compound, when ibuprofen is present in the ethanol, it caused the ethanol and oil to form a homogeneous mixture under all conditions tested in solventadjuvant ratios above 1:2. This observation was very surprising because, although not wish to be bound by any theory, it appears that a therapeutic compound may be having some effect on the manner in which an adjuvant and solvent interact with each other, such that a homogeneous mixture is formed in a way that does not occur when the therapeutic compound is absent. In addition, the results indicate that a therapeutic compound can be formulated at clinically useful concentrations.

Example 2

Liquid Formulations of Pharmaceutical Composition [0217] This example illustrates how to make a pharmaceutical composition as disclosed herein as a liquid formulation.

[0218] To prepare a pharmaceutical composition disclosed herein using gemfibrozil, the following formulations were examined. In these experiments, 600 mg gemfibrozil was contacted with different volumes of ethanol, as the solvent, warmed to 37°C, and the resulting solution was then contacted with different volumes of linseed oil, as the adjuvant, warmed to 37°C (Table 3). Each formulation was evaluated to determine whether or not the ethanol and linseed oil form immiscible layers, a clear homogeneous mixture, as well as whether or not the gemfibrozil crystallized out of solution. The results are summarized in Table 3.

[0219] Like ibuprofen in Example 1 above, gemfibrozil remained insoluble in the oil alone and did not dissolve to substantially measureable degree. The formulation comprising 0.2 mL ethanol was unable to completely dissolve gemfibrozil. In addition, although the formulation comprising 0.3 mL ethanol was capable of dissolving gemfibrozil, the therapeutic compound began to crystallizing out of solution within 3 hours and complete crystallization occurred within 48 hours. All other formulations tested were capable of dissolving gemfibrozil and forming a pharmaceutical composition disclosed herein. However, only the formulation comprising 0.5 mL ethanol appeared to for a stable pharmaceutical composition in that gemfibrozil remained completely dissolved after three weeks.

Example 3

Liquid Formulations of Pharmaceutical Compositions [0220] This example illustrates how to make a pharmaceutical composition as disclosed herein as a liquid formulation.

[0221] To prepare a liquid pharmaceutical composition disclosed herein using ibuprofen, the following method was performed. About 4 g ibuprofen was contacted with 3.6 mL of ethyl acetate, as the solvent, and the resulting solution was then contacted with 76.4 mL of rapeseed oil, as the adjuvant. The resulting pharmaceutical composition had a solvent:adjuvant ratio of about 1:21. This pharmaceutical composition was then placed in a round bottom flask and subjected to low pressure on a rotary evaporator. The temperature was kept low and evaporation continued to constant weight. The total volume lost was 3.65% of the total weight. The resulting liquid no longer retained the characteristic ethyl acetate odor/taste, indicating that there was a substantial removal of ethyl acetate form the pharmaceutical composition.

[0222] To prepare a liquid pharmaceutical composition disclosed herein using ibuprofen, the following method was performed. About 2 g ibuprofen was contacted with 1.2 mL of diethylene glycol monoethyl ether (2-(2-ethoxyethoxy)ethanol), as the solvent, 2.2 mL MAISINE® 35-1 (Gattefosse), a glyceryl monolinoleate, and 2.2 mL rapeseed oil, as the adjuvants, and the resulting mixture was then contacted with 0.46 mL isopropanol. The mixture was added to a vessel heated to about 40°C to about 50°C and stirred until all components of the mixture dissolved and then cooled to about 30°C. The resulting pharmaceutical composition had a solvent:adjuvant ratio of about 1:3.67. This pharmaceutical composition was then aliquoted to produce 10 liquid capsules each containing about 200 mg ibuprofen.

Example 4

Solid Formulation of Pharmaceutical Composition [0223] This example illustrates how to make a pharmaceutical composition as disclosed herein as a solid formulation.

[0224] Since certain fatty acids are liquid at room temperature, while others are solid, an examination of the different fatty acids was undertaken in an effort to evaluate the potential of each fatty acid in the manufacture of a solid formulation. This understanding would enable the development of a wide array of solid formulation by adjusting the relative ratios of each fatty acid. As an initial experiment, linolenic acid, linoleic acid, palmitic acid and stearic acid were evaluated to assess whether it was possible to prepare a pharmaceutical composition disclosed herein that could be formulated using only one of these fatty acids to be a solid or semi-solid at 22°C (simulating room temperature conditions), but melt into a liquid at 37°C (simulating internal body temperature conditions after ingestion).

[0225] Four different test formulations were prepared and evaluated on their ability to form a solid dose formulation at 22°C and melt into a homogeneous solution at 37°C without forming a suspension (Table 4). Formulation 1 was prepared by dissolving 200 mg of Ibuprofen into 400 mg of menthol, and the resulting solution was then mixed with 200 mg of stearic acid (Tm of about 67-72°C) and heated at 60°C for 30 minutes to form a homogeneous solution. Formulation 1 solidified immediately upon cooling to 22°C. Formulation 1 remained a solid even after incubating at 37°C overnight. Formulation 2 was prepared by dissolving 200 mg of Ibuprofen into 400 mg of menthol, and the resulting solution was then mixed with 200 mg of palmitic acid (Tm of about 61-62°C) and heated at 60°C for 30 minutes to form a homogeneous solution. Formulation 2 solidified about 1 hour after cooling to 22°C. Incubating at 37°C overnight cause Formulation 2 to completely melt into a clear homogenous liquid. However, Formulation 2 once again solidified about 1 hour after cooling to 22°C. Formulation 3 was prepared by dissolving 200 mg of Ibuprofen into 400 mg of menthol, and the resulting solution was then mixed with 200 mg of linoleic acid (Tm of about -5°C) and heated at 37°C for 2 hours to form a homogeneous solution. Formulation 3 remained a liquid, even after cooling to 22°C for 72 hours. Formulation 4 was prepared by dissolving 200 mg of Ibuprofen into 400 mg of menthol, and the resulting solution was then mixed with 200 mg of linolenic acid (Tm of about -11°C) and heated at 37°C for 2 hours to form a homogeneous solution. Formulation 4 remained a liquid, even after cooling to 22°C for 72 hours.

[0226] Based on these data, a solid dosage form of a pharmaceutical composition disclosed herein can be made. For example, a pharmaceutical composition will be formulated to be solid or semi-solid at 22°C, but melt into a proper clear solution (and not a suspension) at 37°C (Table 5).

Animal Model for Intestinal Erosion [0235] To assess whether a pharmaceutical composition disclosed herein reduced gastric irritation, experiments were conducted using an intestinal erosion murine model.

[0236] Sprague-Dawley rats were divided into seven experimental groups containing five animals each. After fasting overnight, the animals were challenged with one with one of seven different treatments. Group A was a control in which each mouse was orally administered 1% methylcellulose/0.5% polysorbate 80 vehicle only. Group B was a control in which each mouse was orally administered solvent/adjuvant vehicle only (gavage of 10% ethanol and 90% linseed oil). Group C was a control in which each mouse was orally administered 150 mg/kg aspirin. Group D was a control in which each mouse was orally administered 100 mg/kg ibuprofen suspended in 1% methylcellulose/0.5% polysorbate 80. Group E was the experimental group in which each mouse was administered a pharmaceutical composition disclosed herein (BC1054-100) comprising 100 mg/kg of ibuprofen, 10% ethanol, and 90% linseed oil. Group F was a control in which each mouse was orally administered 100 mg/kg ibuprofen suspended in 1% methylcellulose/0.5% polysorbate 80. Group G was the experimental group in which each mouse was administered a pharmaceutical composition disclosed herein (BC1054-200) comprising 200 mg/kg of ibuprofen, 10% ethanol, and 90% linseed oil. Animals were sacrificed 4 hours after treatment and the stomachs were examined for degree of hemorrhage and severity of mucosal erosive lesions. Gastric irritation was scored as follows: 0, no lesions; 1, hyperemia; 2, one or two slight lesions; 3, more than two slight lesions or severe lesions; and 4, very severe lesions. A score of 50% or more relative to Group C (aspirin-treated control group), which was set to 100%, was considered a positive score for gastric irritation.

[0237] Results are shown in Table 6. Group D (100 mg/kg of ibuprofen-treated control group) and Group F (200 mg/kg of ibuprofen-treated control group) produced gastric lesions that were 75% and 95%, respectively, severe as those induced by Group C (aspirin-treated control group). However, Group E (BC1054-100-treated experimental group) and Group G (BC1054-200-treated experimental group) produced gastric lesions that were 20% and 40%, respectively, as severe as those associated with Group C (aspirin-treated control group). These results demonstrate that that a pharmaceutical composition disclosed herein reduced the extent to which a therapeutic compound may cause mucosal lesions and cause gastric irritation.
