Description

VETERINARY CANNABINOID, MENTHOL AND ANESTHETIC COMPOSITIONS AND

METHODS

FIELD

[0001] The aspects of the present disclosure relate to compositions including active agents such as cannabinoids, menthol and anesthetics.

BACKGROUND

[0002] There is a need for novel treatments for pain and inflammation, particularly in the treatment of oral and dental pain. Some current agents may be ineffective and can, for example, come with unacceptable side effects. Furthermore, there is a growing concern about the overuse of opioid pain treatments.

[0003] Hydrogels can be used as a vehicle for the delivery of drugs and other therapeutically active agents. They refer to a network of hydrophilic polymer chains that are generally found as a colloidal gel in which water is the dispersion medium. Hydrogels are highly absorbent (they can contain over 99.9% water) natural or synthetic polymers and can also possess a degree of flexibility very similar to natural tissue, due to their significant water content ("Terminology of polymers and polymerization processes in dispersed systems (IUPAC Recommendations 2011)". Pure and Applied Chemistry 83 (12): 2229-2259. 2011).

[0004] Hydrogels are characterized by the inclusion of water which acts to disperse the polymer into a colloidal mass. Unfortunately, the presence of water limits the utility of these products to water sensitive materials or environments where moisture is contraindicated. The physical properties of water also dictate the physical properties of the hydrogel, such as reactivity to acids and bases. Thus, there are applications, including the delivery of drugs and other therapeutically active agents, where anhydrous hydrogels (i.e., hydrogels without the aqueous limitations) may be preferred.

One aspect described in conjunction with a particular embodiment is not necessarily limited to that embodiment and can be practiced with any other embodiment(s).

[0013] The use of the terms “a” and “an” and “the” and similar referents in the context of describing the elements (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context. Recitation of ranges of values herein are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended merely to better illuminate the embodiments and does not pose a limitation on the scope of the claims unless otherwise stated. No language in the specification should be construed as indicating any non- claimed element as essential. [0014] Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in this specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by embodiments of the present disclosure. As used herein, “about” may be understood by persons of ordinary skill in the art and can vary to some extent depending upon the context in which it is used. If there are uses of the term which are not clear to persons of ordinary skill in the art, given the context in which it is used, “about” may mean up to plus or minus 10% of the particular term.

[0015] The terms “%”, “% by weight”, “weight %” and “wt%” are all intended to mean unless otherwise stated, percents by weight based upon a total weight of 100% end composition weight. Thus 10% by weight means that the component constitutes 10 wt. parts out of every 100 wt. parts of total composition.

[0016] The term “pharmaceutically acceptable” means that which is useful in preparing a pharmaceutical composition that is generally non-toxic and is not biologically undesirable and includes that which is acceptable for veterinary use and/or human pharmaceutical use.

[0017] The aspects of the disclosed embodiments relate to an anhydrous hydrogel for the delivery of an active agent(s). Particularly important active agents are those that are moisture sensitive. The aspects of the disclosed embodiments also relate to processes for the preparation of, intermediates used in the preparation of, compositions (e.g., pharmaceutical, medical device cosmetic, industrial) containing and the uses of such hydrogels in the treatment of disorders or application of specified agents to a surface.

[0018] One specific embodiment of the present disclosure relates to compositions comprising an active agent (including acceptable salt thereof) pharmaceutical composition. Accordingly, in one embodiment, the present disclosure relates to a pharmaceutical composition comprising an active agent, a pharmaceutically acceptable carrier and, optionally, additional medicinal or pharmaceutical agent(s) [0019] Active agents include pharmaceutical agents such as analgesics, decongestants, bronchodilators and other antiasthmatic agents, cardiovascular agents such as beta-blockers, ACE inhibitors, diuretics, antithrombics, etc., diabetic agents, antihistamines, anesthetics, antifungals, antinauseants, antiemetics, antibacterial agents, antifungal agents, corticosteroids, neurological agents, anti-inflammatories, vaccines, biological agents (such as Humera, Enbrel and Remicade), wound healing agents and anticonvulsants. Vitamins (particularly A, C, D and E) are a particular embodiment of an active agent. The concentration of the active ingredient in the gel base is, of course, dependent on the identity of the active agent, the condition and patient being treated and the potency desired.

[0020] One group of particularly interesting active agents include pharmaceutical agents that are moisture sensitive such as biologicals, enzymes, proteins (and fragments thereof). Other moisture sensitive pharmaceutical agents include Adderall, alprazolam, gemifloxacin, hydromorphone and zolmitriptan.

[0022] Another embodiment of the present disclosure relates to wart removal compounds such as salicylic acids. Such treatments are of specific interest due to heightened response to the anhydrous medium of the hydrogel.

[0023] One specific embodiment relates to wound healing agents and products (such as gauze, bandage, and synthetic skin). Such agents include aloe, benzyl alcohol, coagulants (such as styptic, chitosan, vitamin K, phytomenadione, menadione, etamsylate, carbazochrome Batroxobin), ferric sulfate, ticosan, becaplermin, antimicrobial agents (including antibiotics such as gentamycin, polymyxin B, zinc bacitracin, metronidazole, ofloxacin, minocycline, hydrocortisone, triamcinolone and tetracycline), antifungals, silver, povidone-iodine, polyhexamethylene biguanide, dialkylcarbamoylchloride, lactoferrin, growth factors (such as epidermal growth factor (EGF), platelet derived growth factor (PDGF), fibroblast growth factor (FGF), transforming growth factor (TGF-bl), insulin-like growth factor (IGF-1), human growth hormone, granulocyte macrophage colony stimulating (GM-CSF)).

[0024] Another embodiment relates to scar healing agents such as vitamins, aloe vera, and benzyl alcohol.

[0025] Active agents also includes cosmetic agents such as caffeine, sunscreens (such as butyl methoxydibenzoylmethane, oxybenzone, bumetrizole, ecamsule, phenylbenzimidazole sulfonic acid, ethylhexyl methoxycinnamate, menthyl anthranilate, octocrylene, para-aminobenzoic acid (PABA), and Tinosorb M), anti-inflammatories (such as salicylates), anti-acne agents (such as (isotretinoin, Benzamycin, clindamycin, Erythromycin, minocycline and tretinoin), vitamins (particularly vitamins C and E, Biotin), ubiquinone, retinoids, Minoxidyl, Zinc pyrithion, ketoconazole, allantoin, herbal extracts (such as Passion Fruit extract ( Passiflora Edulis ), Red rose extract, Raspberry extract ( Rubus Idaeus ), Yucca herbal extract, Aloe vera leaf gel, Tea tree oil (.

[0026] One particular cosmetic agent of interest is coenzyme Q10 (Co Q10), also known as ubiquinone, ubidecarenone, coenzyme Q, and abbreviated at times to CoQlO, CoQ or Q10. Ubiquinone is a 1,4-benzoquinone, where Q refers to the quinone chemical group, and 10 refers to the number of isoprenyl chemical subunits in its tail.

[0027] Active agents also include breath fresheners and oral hygienics such as triclosan, chlorhexidine gluconate and complexed metals such as Ag, Cu, Zn or Sn. Dental adhesives such as Gantrez MS-955 polymer (a mixed sodium and calcium salt of methyl vinyl ether and maleic anhydride copolymer supplied as a powder) are also active agents. The formulations of the present disclosure are particularly suitable as dental adhesives demonstrating significant holding power over other adhesive technologies. The formulations of the present disclosure are also useful in the treatment of dry mouth and dry vagina syndromes.

[0028] Active agents also include odor reducing agents such as cyclodextrins, sodium bicarbonate, activated charcoal, potassium bicarbonate, zinc undecylenate, undecylenic acid methyl ester, chlorophyll copper complex (CCC), Grillocin, bismuth compounds such as bismuth salicylate (BiS), bismuth subgallate (BiG) and bismuth citrate (BiC), and esters of 3-methyl-2- hexenoic acid.

[0029] The hydrogels of the present disclosure are also useful for treatment of nipple disorders, delivery of laxatives and anti-diarrheas such as loperamide and bismuth subsalicylate (such as Kaopectate and Pepto-Bismol).

[0030] The hydrogels of the present disclosure are also useful as food additives which can preserve flavor and aroma.

[0031] Flavors and fragrances are well known in the food and cosmetic industry. Many of these compounds are susceptible to hydrolytic deactivation. Formulations of such flavor and fragrance compounds in the hydrogels of the present disclosure have surprising shelf life and release kinetics.

[0032] The formulations of the present disclosure are also useful sensors, electrodes and circuits. The use of these hydrogels in defibrillators is advantageous due to the resilience of the actives in a non-aqueous base.

[0033] The formulations of the present disclosure are also useful in the field of veterinary medicine for the administration of active agents to pets and farm animals.

[0034] The formulations of the present disclosure are also useful as diagnostic tools for the identification of infection, metal contamination and humidity.

[0035] Another embodiment of the present disclosure relates to compositions used as a rheology modifier for gel and liquid formulations.

[0036] The aspects of the present disclosure relate to compositions used to relieve pain (i.e., analgesics) and/or inflammation, methods of making such compositions and methods of using such compositions including, for example, oral or topically applied (e.g., to skin or another body part, e.g., rectally) compositions including pharmaceutical compositions, including analgesic and/or anti-inflammatory pharmaceutical compositions for the treatment of pain and/or inflammation, that contain a pharmaceutically effective amount of a pharmaceutically acceptable and effective cannabinoid, anesthetic and a pharmaceutically acceptable carrier. Such compositions may also include, for example, oral care compositions, including oral care analgesic and/or anti inflammatory compositions for the treatment of oral or dental pain and/or inflammation, that contain a pharmaceutically effective amount of an oral or dental acceptable and effective cannabinoid, anesthetic and an oral or dental acceptable carrier. Such compositions may also include, for example, analgesic and/or anti-inflammatory pharmaceutical compositions for the treatment of pain and/or inflammation that contain a pharmaceutically effective amount of a pharmaceutically acceptable and effective cannabinoid, anesthetic and a pharmaceutically acceptable carrier. Such compositions may also include, for example, oral care analgesic and/or anti-inflammatory compositions for the treatment of oral or dental pain and/or inflammation, including oral care analgesic and/or anti-inflammatory compositions, that contain a pharmaceutically effective amount of an oral or dental acceptable and effective cannabinoid, anesthetic and an oral or dental acceptable carrier.

[0037] The combination of cannabinoid and anesthetic into a single therapeutic composition, for example, a hydrogel vehicle, can provide improved and better focused delivery of the actives to a patient than separately applying the cannabinoid and anesthetic separately (to different areas of the body or layered one on top of another) without the hydrogel vehicle.

[0038] The aspects of the present disclosure also relate to compositions used to relieve pain (i.e., analgesics) and/or inflammation, methods of making such compositions and methods of using such compositions including, for example, veterinary care compositions including veterinary pharmaceutical compositions, including analgesic veterinary pharmaceutical compositions for the treatment of pain, that contain a veterinary pharmaceutically effective amount of a veterinary pharmaceutically acceptable and effective cannabinoid, anesthetic and a veterinary pharmaceutically acceptable carrier. Such compositions may also include, for example, veterinary care compositions, including veterinary care analgesic compositions for the treatment of pain, that contain a veterinary pharmaceutically effective amount of a veterinary acceptable and effective cannabinoid, anesthetic and a veterinary acceptable carrier. Such compositions may also include, for example, veterinary analgesic pharmaceutical compositions for the treatment of pain that contain a veterinary pharmaceutically effective amount of a veterinary pharmaceutically acceptable and effective cannabinoid, anesthetic and a veterinary pharmaceutically acceptable carrier. Such compositions may also include, for example, veterinary analgesic compositions for the treatment of pain, including veterinary analgesic compositions, that contain a veterinary pharmaceutically effective amount of a veterinary acceptable and effective cannabinoid, anesthetic and a veterinary acceptable carrier.

[0039] The above veterinary compositions, methods, etc. the term “veterinary” includes non human animals including small animals, including, for example, dogs and cats, and large animal veterinary including, for example, equine animals (e.g. horses) and bovine animals (e.g., cows).

[0040] The combination of cannabinoid and anesthetic into a single therapeutic composition, for example, a hydrogel vehicle, can provide improved and better focused delivery of the actives to a patient than separately applying the cannabinoid and anesthetic separately (to different areas of the body or layered one on top of another) without the hydrogel vehicle.

[0041] Orally administered including oral care and other pharmaceutical compositions include products which, in the ordinary course of usage, can be swallowed or chewed (e.g., to deliver the therapeutic in the body past the oral cavity), or are not intentionally swallowed initially for purposes of systemic administration of particular therapeutic agents, but is rather retained in the oral cavity or the tissues thereof for a time sufficient to be effective for purposes of therapeutic activity within the oral cavity and surfaces and tissues therein. After being present in the oral cavity for a time sufficient to be effective for purposes of therapeutic activity, they can be removed from the oral cavity or swallowed or chewed and pass through the digestive system for removal. Oral cavity includes teeth, tissues (including mucous membranes and cheek tissue in the oral cavity) and the surfaces thereof present in mouth. Teeth, as used herein, refers to natural teeth as well as artificial teeth or dental prosthesis. The composition may, for example, be administered to patients with oral pain, such as tooth pain, and pain from gums or cheeks following dental procedures, as wells as patients with bleeding gums or areas in the mouth that are suspect to infection. [0042] “Pain” as referred to herein for the composition and method embodiments of the current disclosure and for which an analgesic or pain relieving or pain treating composition or component thereof treats includes, but is not limited to local pain, systemic pain, oral pain, dental pain and general pain, regardless of the location on the body to which the embodiment of the current disclosure is administered.

[0043] “Anti-inflammatory” as referred to herein for the composition and method embodiments of the current disclosure and for which an anti-inflammatory composition or component thereof treats includes, but is not limited to local inflammation, systemic inflammation, oral inflammation, dental inflammation and general inflammation, regardless of the location on the body to which the embodiment of the current disclosure is administered.

[0044] Cannabinoids are an active agent and a class of chemical compounds that can be derived from plants (phytocannabinoids) or synthetically produced. Cannabinoids can have local and systemic analgesic, pain relieving, pain treating and anti-inflammatory therapeutic properties. Cannabinoids may also have other medical benefits and/or be useful in treating other medical conditions including, for example, reduction of anxiety and depression, reduction of symptoms like nausea, vomiting and pain related to cancer treatments, reduction of acne, protection of the neural system and benefits for the heart and circulatory system by the lowering of blood pressure.

[0045] Examples of phytocannabinoids include Cannabidiol (CBD) including, for example, full spectrum hemp oil, CBD oil including full spectrum CBD oil, Cannabinol (CBN) and tetrahydrocannabinol (THC), the latter being a known psychotropic compound and the first two being non-psychotropic. Cannabis plants can exhibit wide variation in the quantity and type of cannabinoids they produce. Selective breeding of the plants can be used to control the genetics of plants and modify the cannabinoids produced by the plant. For example, there are strains that are used as fiber (commonly called hemp) and, as a result, have been bred such that they are low in psychoactive chemicals like THC. Such strains (e.g., hemp) used in medicine are, for example, often bred for high CBD content and cannabinoids included herein have minimal levels of THC (less than 0.3%). Examples of oral or pharmaceutically effective cannabinoids include CBD (for example, full spectrum hemp or CBD oil). Cannabinoid, including, for example, phytocannabinoids including CBD or full spectrum hemp or CBD oil, can be in an amount of about 0.1 wt% to about 20 wt %, about 0.1 wt% to about 10 wt %, about 0.5 wt% to about 6 wt%, about 1 wt% to about 20 wt%, about 3 wt% or about 5.7 wt%. CBD can be in an amount of about 0.1 wt% to about 20 wt %, about 0.1 wt% to about 10 wt %, about 0.5 wt% to about 5 wt%, about 0.5 wt% to about 2 wt% or about 1.9 wt%. Unit dosage formulations of the embodiments of the present disclosure can include cannabinoid, for example, a phytocannabinoid (including for example, CBD or full spectrum hemp oil) in the amount of about 2 mg. to about 60 mg., about 5 mg. to about 30 mg., about 5 mg to about 15 mg. about 15 mg. to about 30 mg. or about 30 mg. to about 45 mg. Unit dosage formulations of the embodiments of the present disclosure can include CBD or full spectrum hemp oil in the amount of about 2 mg. to about 30 mg., about 5 mg. to about 30 mg., about 5 mg. to about 15 mg., about 15 mg. to about 30 mg. or about 10 mg. Unit doses of CBD oil content can include an amount of about 2 mg. to about 60 mg. An effective amount of cannabinoid includes an analgesic, pain relieving, pain treating or anti-inflammatory amount of cannabinoid. An effective amount can also include a veterinary effective amount of CBD or full spectrum hemp oil for the aforementioned maladies. Cannabinoids can also have therapeutic value as a nutrient and can be included in composition and method embodiments of the present disclosure in an effective amount to perform that function.

[0046] For embodiments of the present disclosure including veterinary compositions (including rectal delivery systems including suppositories) and methods, unit dosage formulations of the embodiments of the present disclosure can include cannabinoid, for example, a phytocannabinoid (including for example, CBD or full spectrum hemp oil) in the amount of about 5 mg. to about 1500 mg., about 5 mg. to about 20 mg. (e.g., small animals), about 100 mg. to about 1500 mg.(e.g., large animals), about 500 mg. to about 1500 mg., about 1000 mg. or about 40 mg/lOOkg of animal weight and unit dosage formulations of the embodiments of the present disclosure can include CBD in the amount of about 5 mg. to about 1500 mg., about 5 mg. to about 20 mg. (e.g., small animals), about 100 mg. to about 1500 mg. (e.g., large animals), about 500 mg. to about 1500 mg., about 1000 mg. or about 40 mg/ 100kg of animal weight.

[0047] Cannabinoids, for example, CBD can have a local and/or a systemic effect and may reduce pain imparting and regulating the endocannabinoid (neurotransmitter of the nervous system) receptor activity. The subsequent body functions that may be regulated include pain, sleep, appetite and immune system response (through, at least, in part, by reducing inflammation). [0048] For the purpose of the present disclosure, the word “cannabinoid” refers to one or more cannabinoids or cannabinoid compounds or oils or extracts from plants (for example, hemp including hemp oil, full spectrum hemp oil, CBD oil, full spectrum CBD oil, Cannabis sativa seed oil, etc.) that include one or a plurality of phytocannabinoids.

[0049] Full spectrum hemp oil is oil derived from the entire plant except the flower (which contains THC) and can have over 85 phytocannabinoids which can have a positive synergistic effect as compared to compositions having fewer cannabinoids. There may also be benefits to other components of it (e.g., terpenes). Such benefits and effect may include faster penetration and/or permeation of the therapeutic components thereof. Full spectrum hemp oil can include full spectrum hemp oil that has been purified to include less than the below stated amounts of one or more of the following impurities:

Aflatoxins Bl, 82, Gl, G2 (fats, oils, lecithin, egg powder): <0.1 pg/kg of each of Aflatoxin Bl, Aflatoxin B2, Aflatoxin Gl and Aflatoxin G2, Sum of all positive Aflatoxins <0.4 pg/kg. GlyphosatelAMPAiGlufosinate: <0.1 mg/kg of each of Glufosinate, Glyphosate and Aminomethylphosphonic acid (AMP A)

Mercury: <0.02 mg/kg Arsentic: <0.03 mg/kg Cadmium: <0.01 mg/kg Lead: <0.05 mg/kg.

[0050] Menthol is an active agent and an organic compound that can be made synthetically or obtained from mint oils such as com mint and peppermint. Medicinally, it been found that menthol can have anesthetic (e.g., local) by, for example, blocking nerve signal transmission) and counterirritant properties as well as anti-inflammatory properties (e.g., systemic and local) when administered to a patient. . Furthermore, menthol is a vasodilator that can accelerate the transport of active in the circulatory system. In a rectal delivery system, menthol may not only reduce inflammation and pain, but also produce a cooling, soothing effect. In general, the action of local anesthetics can restrict to the site of application and rapidly reverses upon diffusion from the site of action in the nerve. Local anesthetics can also serve an important function in providing peripheral pain relief. Topical administration of pain-relieving anesthetics can provide important advantages over systemic or local, non-topical administration. Menthol can be in an amount of about 0.05 wt% to about 20 wt %, about 0.1 wt% to about 10 wt %, about 1 wt% to about 20 wt%, about 0.1 wt% to about 14 wt%, about 0.1 wt% to about 1 wt %, about 2 wt% to about 9 wt% about 0.62 wt%,. Unit dosage formulations of the embodiments of the present disclosure can include menthol in the amount of about 2 mg. to about 20 mg., about 2 mg. to about 10 mg., about 2 mg. to about 4 mg., about 3 mg. to about 4 mg., about 5 mg. to about 7 mg., about 8 mg. to about 10 mg., about 4 mg. to about 8 mg. or about 5 mg. to about 7 mg.

[0051] For embodiments of the present disclosure including veterinary compositions (including rectal delivery systems including suppositories) and methods, unit dosage formulations of the embodiments of the present disclosure can include menthol in the amount of about 30 mg. to about 1500 mg, about 30 mg to about 100 mg, about 100 mg to about 200 mg, about 200 mg to about 450 mg., about 450 mg to about 6000 mg., about 600 mg to about 800 mg., about 800 mg to about 1100 mg., about 1100 mg to about 1500 mg. An effective amount of menthol includes an anesthetic, pain reducing (e.g., analgesic) or anti-inflammatory effective amount of menthol. An effective amount can also include a veterinary effective amount of menthol for the aforementioned maladies.

[0052] The aspects of the present disclosure also relate to embodiments including compositions, methods of making and methods of using included herein which also comprise the menthol component included in embodiments of the present disclosure in a stabilized menthol composition as well as methods of making and using them including a mixture of (a) menthol and (b) a menthol stabilizer compound including undecylenic acid methyl ester or undecylenic acid or a salt (preferably a pharmaceutically acceptable salt) thereof where the menthol in the stabilized menthol compositions is less susceptible to volatizing into a gas and remains in a form that can be administered in a composition in an amount closer to the amount originally included in the composition when formulated with less menthol volatizing away (i.e., lowering the rate of volatilization of the menthol from what it would be for menthol alone) from the original concentration and, thus, lowering the original concentration and diminishing the amount of the menthol originally added.

[0053] Undecylenic acid salts, including pharmaceutically acceptable salts may include, for example, inorganic acid addition, hydrochloride salts, sulfate and phosphate salts; and organic acid addition salts, such as alkyl sulfonate, arylsulfonate, acetate, maleate, fumarate, tartrate, citrate and lactate and metal salts including alkali metal salts, such as lithium salt, sodium salt and potassium salt and alkaline earth metal salts, such as magnesium salt and calcium salt, strontium salt, aluminum salt and zinc salt, and other multivalent salts such as for example, zirconium, iron, copper, silver, bismuth etc. Additionally primary secondary, and tertiary amine salts, organic and inorganic, mono and polyamines compounds could utilized. Examples include compounds such as urea, and amino acids such as lysine, histidine, arginine etc, could be utilized.

[0054] The stabilized menthol compositions can made by mixing together (a) menthol and (b) a menthol stabilizer compound in a ratio of (a) about 1 molar part menthol to (b) the amount of one or more than one of the menthol stabilizer compounds (undecylenic acid methyl ester, undecylenic acid or a salt (preferably a pharmaceutically acceptable salt) of undecylenic acid, including mixtures thereof) of from about 0.005 molar part to about 1.00 molar part, about 0.010 molar part to about 0.750 molar part, about 0.020 molar part to about 0.50 molar part, about 0.050 molar part to about 0.250 molar part, or about 0.10 molar part. It is believed that the menthol stabilizer compounds (e.g., undecylenic acid methyl ester and others included herein) and menthol may associate to form a menthol analog where the menthol analog’ s vapor pressure becomes lower than menthol itself. As a result of having a lower vapor pressure, the menthol component of the menthol analog volatizes as a lower rate than menthol by itself.

[0055] One possible explanation for the stabilization of menthol by the compound of formula (I) may be that the menthol associates with the alkenyl side chain of the menthol stabilizer compounds may provide a molecular attraction connecting the menthol stabilizer compounds and a menthol molecule, such that more than one menthol molecule may associate with a molecule of one of the menthol stabilizer compounds.

[0056] The stabilized menthol compositions including menthol and at least one of the menthol stabilizer compounds (e.g., undecylenic acid methyl ester and others included herein) can be also be made first by dissolving menthol in a pharmaceutically acceptable suitable solvent such as, for example, as a low, medium, or long chain triglyceride. Examples of such solvents are coconut oil, olive oil, palm oil, hemp oil and castor oil. Still other acceptable solvents, such as alcohols, ethers and polyalcohols, for example, propylene glycol, butylene glycol, and polyethylene glycols (PEGs) can also be used. The desired amount of at least one of the menthol stabilizer compounds disclosed herein (e.g., undecylenic acid methyl ester and others disclosed herein) is then added to that mixture. Such compositions that include menthol, solvent and one or more than one of the menthol stabilizer compounds included herein may be made where the mixture of the these ingredients includes a molar ratio of about one molar part menthol to a range of from about 0.0050 molar part to about 1.00 molar part, about 0.010 molar part to about 0.750 molar part, about 0.020 molar part to about 0.50 molar part, about 0.050 molar part to about 0.250 molar part, or about 0.10 molar part of at least one of the menthol stabilizer compounds (i.e., one of the menthol stabilizer compounds or a mixture of more than one of the menthol stabilizer compounds) included herein, preferably a molar ratio of about one molar part menthol to at most about 0.50 molar part, at most about 0.250 molar part or at most about 0.10 molar part of one or more than one of the menthol stabilizer compounds included herein. Such mixtures of menthol, solvent and menthol stabilizer compounds may be used when smaller amounts of menthol need to be stabilized (where the amount of menthol stabilizer compound to be mixed with the menthol is so small that there isn’t enough of it to dissolve the menthol).

[0057] Both menthol stabilized compositions (i.e., where the menthol is first dissolved in a solvent then dissolved in a menthol stabilizer compound included herein or where the menthol is directly dissolved in a menthol stabilizer compound included herein) can be used in orally administrated and non-orally administrated compositions (e.g., non-orally topically administrated compositions (e.g., place on the skin or other external tissues)). However, the menthol stabilizer compounds can have a bitter taste. The dissolving of the menthol in solvent prior to the addition of at least one of the menthol stabilizer compounds included herein is preferably used in menthol containing therapeutic compositions to be administered orally because by first dissolving the menthol in a suitable solvent, less of the menthol stabilizer compounds may be used, thus lessening the bitter taste of the menthol stabilized composition and the final product in which it is included that is imparted by the menthol stabilizer compound.

[0058] The word “anesthetic” can refers to one or more anesthetics or anesthetic compounds. Anesthetics, for example, local anesthetics and topical anesthetics, prevent, block, relieve or reduce pain by interrupting nerve conduction (e.g., blocks nerve signals) and are an active agent. When applied locally to nerve tissue in effective concentrations, local anesthetics can reversibly block the action potentials responsible for nerve conduction. In general, the action of local anesthetics can restrict to the site of application and rapidly reverses upon diffusion from the site of action in the nerve. Local anesthetics can also serve an important function in providing peripheral pain relief. Furthermore, some anethetics (e.g., benzocaine, lidocaine and mepivacaine) can be a vasodilator, can have counterirritant properties as well as have a soothing effect. Such vasodilator properties can accelerate the transport of actives in the circulatory system. Topical administration of pain-relieving anesthetics can provide important advantages over systemic or local, non-topical administration. Examples of oral or pharmaceutically effective anesthetics include benzocaine, lidocaine and mepivacaine. Anesthetics, including, for example, benzocaine, can be in an amount of about 0.1 wt% to about 20 wt %, about 0.1 wt% to about 10 wt %, about

1 wt% to about 20 wt%, about 0.1 wt% to about 14 wt%, about 0.1 wt% to about 1 wt %, about

2 wt% to about 9 wt% about 0.62 wt%,. Unit dosage formulations of the embodiments of the present disclosure can include anesthetic in the amount of about 2 mg. to about 20 mg., about 2 mg. to about 10 mg., about 2 mg. to about 4 mg., about 3 mg. to about 4 mg., about 5 mg. to about 7 mg., about 8 mg. to about 10 mg., about 4 mg. to about 8 mg. or about 5 mg. to about 7 mg. An effective amount of an anesthetic, for example benzocaine, includes an anesthetic effective amount of anesthetic including a pain reducing (e.g., analgesic) effective amount.

[0059] For embodiments of the present disclosure including veterinary compositions (including rectal delivery systems including suppositories) and methods, unit dosage formulations of the embodiments of the present disclosure can include anesthetic, for example, benzocaine, in the amount of about 30 mg. to about 1500 mg, about 30 mg to about 100 mg, about 100 mg to about 200 mg, about 200 mg to about 450 mg., about 450 mg to about 6000 mg., about 600 mg to about 800 mg., about 800 mg to about 1100 mg., about 1100 mg to about 1500 mg.

[0060] For embodiments of the present disclosure including veterinary compositions (including rectal delivery systems including suppositories) and methods, unit dosage formulations of the embodiments of the present disclosure can include the following for example:

[0086] Glycerin (also commonly known as glycerol, glycerin, propanetriol and 1,2,3- trihydroxypropane) is a widely used commercial product with over a million tons produced annually. High purity glycerin (>99.5%) is known. Anhydrous glycerin refers to glycerin with minimal residual water. United States Pharmacopeia (USP) describes one recognized standard of high purity anhydrous glycerin (>99.0-101.0%) as containing not more than 0.5% water. The otic therapeutic Auralgan is described as containing USP glycerin with not more than 0.6% water. The present disclosure includes such glycerin containing 0.5% and lower residual water. Specific embodiments include 99.7% (weight) water free, 99.8%, 99.9% and absolute (100%) (i.e. less than 0.3%, 0.2%, 0.1% residual water).

[0087] Sodium carboxymethyl cellulose is a cellulose derivative with carboxymethyl groups (-CH2-CO2H) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. Commercial polymer products are typically categorized by average glucopyranose chain length molecular weights (MW) of 70,000, 80,000, 90,000 g/m. Anhydrous sodium carboxymethyl cellulose refers to a product with minimal residual water, such as, sodium carboxymethyl cellulose containing less than 0.5 % residual water , less than 0,3 % residual water and less residual water. Specific embodiments can include 99.5%, 99.7% (weight) water free, 99.8%, 99.9% and absolute (100%) (i.e. less than 0.5%, 0.3%, 0.2%, 0.1% residual water).

[0088] The combination of anhydrous glycerin and anhydrous sodium carboxymethyl cellulose (CMC) yields an anhydrous material that upon addition of heat (or radiation) is transformed into an anhydrous hydrogel. Unit dosage formulations of the embodiments of the present disclosure may be prepared by the addition of about 2 mg. to about 20 mg., about 2 mg. to about 60 mg., about 5 mg. to about 30 mg., about 5 mg. to about 15 mg., about 15 mg. to about 30 mg. or about 30 mg. to about 45 mg. of cannabinoid, , for example, full spectrum hemp oil. Unit dosage formulations of the embodiments of the present disclosure can include CBD or full spectrum hemp oil in the amount of about 2 mg. to about 30 mg., about 5 mg. to about 30 mg., about 5 mg. to about 15 mg., about 15 mg. to about 30 mg. or about 10 mg., for example, a phytocannabinoid or full spectrum hemp oil, and about 2 mg. to about 20 mg., about 2 mg. to about 10 mg., about 2 mg. to about 4 mg., about 3 mg. to about 4 mg., about 5 mg. to about 7 mg., about 8 mg. to about 10 mg., about 4 mg. to about 8 mg. or about 5 mg. to about 7 mg. of each of at least one of menthol and anesthetic, for example, benzocaine, with glycerin and CMC is likewise transformed into a homogeneous hydrogel upon the addition of heat. These products, anhydrous hydrogels, can have less than 0.5% water, more preferably less than 0.4% water, more preferably less than 0.3% water.

[0089] Such anhydrous hydrogels are hygroscopic and thus may be subject to post production processes that maintain the product in a water-free state. One such method is coating of the hydrogel with a hydrophobic layer. Alternate methods include storage of products in moisture free containers. Many of the products once formed may be stable enough to atmospheric moisture such that they can be stored in standard delivery apparatus.

[00113] Embodiments of the present disclosure may be formulated to be immediate and/or modified release. Modified release formulations include delayed-, sustained-, pulsed-, controlled, targeted and programmed release.

[00114] Suitable modified release formulations for the purposes of the present disclosure may be adapted, for example, from those described in US Patent No. 6,106,864. Details of other suitable release technologies such as, for example, high energy dispersions and osmotic and coated particles are to be found in Pharmaceutical Technology On-line, 25(2), 1-14, by Verma et al (2001). The use of chewing gum to achieve controlled release may be adapted from those described in WO 00/35298.

[00115] Other embodiments of the present disclosure include a method of relieving pain and /or inflammation by topically administering to the oral cavity, for example, an oral mucous membrane and cheek tissue in the oral cavity, of a mammal in need of such treatment at least one of the compositions disclosed herein. Still other embodiments of the present disclosure include a method of relieving mouth, oral or dental pain by topically administering to the oral cavity, for example, an oral mucous membrane and cheek tissue in the oral cavity, of a mammal in need of such treatment at least one of the compositions disclosed herein. Still other embodiments of the present disclosure include a method of relieving pain and /or inflammation by administering to the oral cavity, for example, an oral mucous membrane and cheek tissue in the oral cavity, of a mammal in need of such treatment at least one of the compositions disclosed herein to a tooth, teeth or other oral tissues or surfaces. Still other embodiments of the present disclosure include a method of relieving mouth, oral or dental pain and /or inflammation by topically administering to the oral cavity, for example, an oral mucous membrane and cheek tissue in the oral cavity, of a mammal in need of such treatment at least one of the compositions disclosed herein to a tooth, teeth or other oral tissues or surfaces.

[00116] Other embodiments of the present disclosure include a method of relieving pain and /or inflammation by rectally administering to the rectal cavity of a non-human mammal in need of such treatment at least one of the compositions disclosed herein. Methods of the present disclosure can also include a step-wise method of gradually increasing the dosage for effect, including, for example, breaking a 1000 mg. CBD or full spectrum hemp oil suppository in half resulting in a 500 mg. CBD or full spectrum hemp oil suppository for administration.

[00117] The embodiments of the present disclosure can include a rectal delivery system (e.g., suppository) having a mass in an amount ranging from about 5 g. to about 10 g., for example, for large animals a mass of about 15 g. including, for example, about 300 mg. of CBD or full spectrum hemp oil. [00118] An embodiment of the present disclosure can include one of the formulation embodiments of the present disclosure is illustrated in FIG. 1. FIG. 1 includes a suppository 100 to be administered rectally to a non-human, for this embodiment a large animal, e.g., a horse. Suppository 100 includes a body 102 with a generally cylindrical shape and a cylindrical surface 103 and ends 104 and 106. Suppository 100 has a length 108 ranging from about 3 in. to about 4 in. and a generally circular cross-section 110 having a diameter 112 ranging from about 0.5 in. to about .75 in., 0.5 in. to about 0.62 in. In the FIG. 1 embodiment show, end 104 has a generally tapered or rounded shape and end 106 has a generally flat shape. Other embodiments of the present disclosure can have both ends with a tapered or rounded shape or both ends with a generally flat shape.

[00119] FIGS. 2A and 2B include an illustration of the butt end of a non-human 200 (e.g., a large animal, including for example a horse) including the rectal region 202 of the non-human 200 and one of the suppository embodiments of the present disclosure 204 inserted into the rectal region 202 and positioned at 206 so that the exterior surface 205 of the suppository 204 in contact with the interior wall 208 of the rectal region 202. The position can include the end 210 of the embodiment 204 being about an inch from the end 212 of the rectal region 202. Such a positioning in the rectal region can provide for optimum administration of the agents included therein (e.g., CBD or full spectrum hemp oil and anesthetic, for example, benzocaine,) for transdermal delivery of those agents in suppository 204 through and into the tissue of the rectal region that the suppository is in contact with to bring about the intended local and/or systemic effect.

[00120] It has been surprisingly found that the combination of anhydrous glycerin and sodium carboxymethyl cellulose (CMC) yields an anhydrous material that upon addition of heat (or radiation) is transformed into an anhydrous hydrogel. Unit dosage formulations may be prepared by the addition of 0.1 mg. to 1 g of active agent (depending on the active agent) with glycerin and CMC is likewise transformed into a homogeneous hydrogel upon the addition of heat. These products have less than 0.5% water, more preferably less than 0.4% water, more preferably less than 0.3% water.

[00121] Hydrogels of the present disclosure can be subjected to crosslinking methods which enhance the structure and function of the hydrogel. Suitable crosslinking chemical agents include divalent/multivalent metallic cations (e.g., calcium, magnesium, zinc, copper, barium, iron, aluminium, chromium, cerium), phosphates (e.g., pentasodium tripolyphosphate (TPP)), chromates (e.g., dipotassium dichromate), borates (e.g., sodium tetraborate decahydrate), peroxides (e.g., t-butyl hydroperoxide), glycidyl(meth)acrylate, ethylene glycol diglycidyl ether, glutaraldehyde, glycerin, glycols, polyamidoamine epichlorohydrin resin, TMPTA, and the like, and mixtures thereof. Representative crosslinking methods include thermogelation, ionotropic gelation, cryogelation, radiation-induced gelation, chemical gelation, coagulation, crystallization, vulcanization, curing, and combinations thereof.

[00122] Another embodiment of the present disclosure relates to anhydrous hydrogels additionally comprising multivalent metal ions (i.e. Ca++, Mg++, Fe+++, Zn++ etc) which may be used to modify the cohesive and solubility characteristics as desired. So-called cross-linking resulting from multivalency makes the products more viscous and less hydrophilic.

[00123] The anhydrous hydrogels of the present disclosure may further comprise a buffer such as an acid such as citric acid, benzoic acid, salicylic acid, etc.; neutral buffers such as phosphate buffered saline etc.; or alkaline buffers such as borates etc. These buffering agents may be used to adjust for pH sensitive applications.

[00124] Another embodiment of the present disclosure relates to a composition of any of the aforesaid embodiments of hydrogel wherein said composition is in thin film, tablet, capsule, oral solution, or oral suspension dosage form.

[00125] Formulations suitable for oral administration include solid, semi-solid and liquid systems such as soft or hard capsules containing multi- or nano-particulates, liquids, or powders; lozenges (including liquid-filled); chews; gels; fast dispersing dosage forms; films; ovules; sprays; and buccal/mucoadhesive patches.

[00126] The hydrogels of the present disclosure may also be administered topically, (intra)dermally, or transdermally to the skin or mucosa. Typical formulations for this purpose include gels, hydrogels, lotions, solutions, creams, ointments, dusting powders, dressings, foams, films, skin patches, wafers, implants, sponges, fibres, bandages and microemulsions. Liposomes may also be used. Typical carriers include alcohol, mineral oil, liquid petrolatum, white petrolatum, glycerin, polyethylene glycol and propylene glycol. Penetration enhancers may be incorporated — see, for example, J Pharm Sci, 88 (10), 955-958, by Finnin and Morgan (October 1999).

[00127] Another embodiment of the present disclosure relates to a composition containing particles which have a core containing an active agent or a salt thereof coated with a barrier layer. The barrier layer is formed from a coating liquid that contains a least one water insoluble barrier forming component selected from a group consisting of ethyl cellulose, copolymers of acrylic and methacrylic esters and natural or synthetic waxes, and a plasticizer.

[00128] Administration of the compounds of Formula I may be effected by any method that enables delivery of the compounds to the site of action. These methods include oral routes, intraduodenal routes, parenteral injection (including intravenous, subcutaneous, intramuscular, intravascular or infusion), topical, and rectal administration.

[00129] The amount of the active agent administered will be dependent on the subject being treated, the severity of the disorder or condition, the rate of administration, the disposition of the compound and the discretion of the prescribing physician. However, an effective dosage is in the range of about 0.001 to about 100 mg. per kg body weight per day, preferably about 1 to about 35 mg./kg/day, in single or divided doses. For a 70 kg human, this would amount to about 0.05 to about 7 g/day, preferably about 0.1 to about 2.5 g/day. In some instances, dosage levels below the lower limit of the aforesaid range may be more than adequate, while in other cases still larger doses may be employed without causing any harmful side effect, provided that such larger doses are first divided into several small doses for administration throughout the day.

[00130] As used herein, the term “combination therapy” refers to the administration of an active agent together with an at least one additional pharmaceutical or medicinal agent, either sequentially or simultaneously.

[00131] The present disclosure includes the use of a combination of an active agent and one or more additional pharmaceutically active agent(s). If a combination of active agents is administered, then they may be administered sequentially or simultaneously, in separate dosage forms or combined in a single dosage form. Accordingly, the present disclosure also includes pharmaceutical compositions comprising an amount of: (a) a first agent comprising an active agent or a pharmaceutically acceptable salt of the compound; (b) a second pharmaceutically active agent; and (c) a pharmaceutically acceptable carrier, vehicle or diluent.

[00132] The manufacture of the anhydrous hydrogels may be achieved using a coating line with a heat tunnel, coating a mixture of glycerin (anhydrous) with NaCMC (anhydrous) to a desired thickness and passing the mixture through an oven (under suitable dry conditions so as to retain water free atmosphere) at 105° C. (min) for about 5 minutes (min) until mixture sets. The product may be extruded into molds or thin films. Active agents and additional components are either anhydrous or dehydrated before use. Subject mixture is treated to the same processing parameters as the coating line.

[00133] Preferably the composition is extruded directly onto a substrate such as a backing layer or release liner, and then pressed. The thickness of the resulting hydrogel-containing film, for most purposes, will be in the range of about 0.20 mm to about 0.80 mm, more usually in the range of about 0.37 mm to about 0.47 mm.

[00134] The hydrogel compositions of the present disclosure may be prepared by solution casting, by admixing the glycerin and CMC at a concentration typically in the range of about 35% to 60% w/w followed by the addition of heat or radiation. The resulting solution is cast onto a substrate such as a backing layer or release liner. Both admixture and casting are preferably carried out at as low temperature as permitted. The substrate coated with the hydrogel film is then baked at a temperature in the range of about 80 degree C. to about 100 degree C., optimally about 90 degree C., for time period in the range of about one to four hours, optimally about two hours.

[00135] Films in accordance with the present disclosure are typically prepared by evaporative drying of thin aqueous films coated onto a peelable backing support or paper. This may be done in a drying oven or tunnel, typically a combined coater dryer, or by freeze-drying or vacuuming.

[00136] Systems for the topical, transdermal or transmucosal administration of an active agent may comprise: a reservoir containing a therapeutically effective amount of an active agent; an adhesive means for maintaining the system in active agent transmitting relationship to a body surface; and a backing layer as described above, wherein a disposable release liner covers the otherwise exposed surface, protecting such surface during storage and prior to use (also as described above).

[00137] The composition will contain a quantity of an active agent effective to provide the desired dosage or effect over a predetermined delivery period.

[00138] The compositions of the present disclosure may also include a rate-controlling membrane on the body surface side of the drug reservoir. The materials used to form such a membrane are selected to limit the flux of one or more components contained in the drug formulation, and the membrane may be either microporous or dense. Representative materials useful for forming rate-controlling membranes include polyolefins such as polyethylene and polypropylene, polyamides, polyesters, ethylene-ethacrylate copolymer, ethylene-vinyl acetate copolymer, ethylene-vinyl methylacetate copolymer, ethylene-vinyl ethylacetate copolymer, ethylene-vinyl propylacetate copolymer, polyisoprene, polyacrylonitrile, ethylene -propylene copolymer, polysiloxane-polycarbonate block copolymer and the like.

[00139] The compositions of the present disclosure may also serve to deliver an active agent using other routes of administration. For example, the compositions may be formulated with excipients, carriers and the like suitable for oral administration of an orally active drug. The compositions may also be used in buccal and sublingual drug delivery, insofar as the compositions can adhere well to moist surfaces within the mouth. In buccal and sublingual systems, hydrolyzable and/or bioerodible polymers may be incorporated into the compositions to facilitate gradual erosion throughout a drug delivery period. Still other types of formulations and drug delivery platforms may be prepared using the present compositions, including implants, rectally administrable compositions, vaginally administrable compositions, and the like.

[00140] An example of such a kit is a so-called blister pack. Blister packs are well known in the packaging industry and are being widely used for the packaging of pharmaceutical unit dosage forms (tablets, capsules, and the like). Blister packs generally consist of a sheet of relatively stiff material covered with a foil of a preferably transparent plastic material. During the packaging process recesses are formed in the plastic foil. The recesses have the size and shape of the tablets or capsules to be packed. Next, the tablets or capsules are placed in the recesses and the sheet of relatively stiff material is sealed against the plastic foil at the face of the foil which is opposite from the direction in which the recesses were formed. As a result, the tablets or capsules are sealed in the recesses between the plastic foil and the sheet. Preferably the strength of the sheet is such that the tablets or capsules can be removed from the blister pack by manually applying pressure on the recesses whereby an opening is formed in the sheet at the place of the recess. The tablet or capsule can then be removed via said opening.
