- Opioid pain medications have been widely prescribed to treat severe and chronic pain.
- a significant increase in opioid prescriptions began in the 1990s and has continued to increase dramatically through the current day.
- the number of prescriptions for opioid painkillers jumped from 76 million to approximately 207 million between 1991 and 2013.
- prescription opioids work to dampen pain signals from the body, but the ensuing psychological effects, like euphoria and extreme relaxation, can lead to abuse and addiction. The summation of these effects proves intensely rewarding to those abusing them, eliciting persistent alterations in brain chemistry that may further compel an individual to use the drug beyond the prescribed use of treating pain.
- This dependency and recreational use of prescription opioids has reached epidemic levels, with an estimated 130 people a day dying from opioid related overdoses in the United States.
- Applicant has identified new compositions that utilize components from cannabis including CBD, THC, cannabinoids as a class of compounds, and terpenes to treat opioid use disorder, to reduce the dependency on opioids, to provide pain relief, reduce anxiety, reduce inflammation, provide vascular combination, and be synergistic or in competition with opioid receptors.

- Applicant proposes new therapeutic materials comprising a carrier, and an admixture of cannabinoid and terpene compounds that together form a novel combination with synergistic impacts to treat addiction specifically related to opioid use disorder, including treatment of reducing anxiety, reducing cravings, and reducing pain and inflammation.
- opioid use disorder a key target of the compositions described herein is the treatment of opioid use disorder.
- Opioids have long been used for their therapeutic properties, namely reduction of pain, but they have also been abused for centuries for their ability to induce euphoria. Their use and abuse modernly and historically are a scourge. Today, nearly 50,000 deaths each year are attributed to opioid overdoses in the United States alone.
- Treatment for opioid use disorder often includes therapy with one of methadone or buprenorphine. Additional options include the use of naltrexone, though its use for long-term treatment is under review. Therapeutics are needed to provide new and improved treatment options, as relapse with any of the prior art drugs is prevalent and some even become addicted to the treatment drugs.
- a key issue in treatment remains the reduction of a series of maladies including pain, inflammation, depression, and anxiety. Applicant has created a new formulation that seeks to treat several of these maladies in order to create a superior composition for long term opioid use disorder treatment.

- CBD extract refers to an extract of a cannabis or hemp plant having at least 1% of CBD.
- the CBD extract comprises at least 10% CBD, and more preferably more than 25%, more than 50%, more than 75%, and more than 95%.
- Selective extraction procedures can be utilized by those of ordinary skill in the art to create extracts that are high in certain cannabinoid compounds, such as CBD.
- the cannabis plant is a flowering plant in the family cannabaceae, which is an annual dioecious, flowering herb.
- the leaves are palmately compound or digitate with a well-known serrated leaflet.
- the first pair of leaves usually have a single leaflet, the number gradually increasing up to a maximum of about 13.
- the leaves have a striking orientation and pattern that enables even persons vaguely familiar with the plant to distinguish a cannabis leaf from unrelated species.
- Cannabis plants are predominately dioecious, having male and female flowers occurring on separate plants. There are several different species that are cultivated, with the two most common being C. sativa and C. indica. Of these, the C.
- sativa plant typically grows larger and results in greater biomass for use in extracting cannabinoid molecules, and for growing biomass for use in hemp-based products.
- the term“cannabis plant” refers to all varietals of cannabis including those high and low in either THC or CBD concentrations, and including industrial hemp.
- the cannabis plant produces a group of chemicals called cannabinoids, among which is A 9 -tetrahydrocannabinol (THC), which is a psychoactive compound having receptors in the mammalian body.
- cannabinoids A 9 -tetrahydrocannabinol (THC)
- THC tetrahydrocannabinol
- cannabinoids has been hampered by the psychoactive properties of some compounds (e.g., Dronabinol) as well as their low bioavailability when administered orally.
- Bioavailability refers to the extent and rate at which the active moiety (drug or metabolite) enters systemic circulation, thereby accessing the site of action.
- the low bioavailability of orally ingested cannabinoids (from about 6% to 20%; Adams & Martin (1996) Addiction 91 : 1585-614; Agurell et al. (1986) Pharmacol. Rev. 38: 21-43; Grotenhermen (2003) Clin. Pharmacokinet.
- Cannabinoids are a heteromorphic group of chemicals which directly or indirectly activate the body’s cannabinoid receptors.
- cannabinoids There are three main types of cannabinoids: herbal cannabinoids that occur uniquely in the cannabis plant, synthetic cannabinoids that are manufactured, and endogenous cannabinoids that are produced in vivo.
- Herbal cannabinoids are nearly insoluble in water but soluble in lipids, alcohol, and nonpolar organic solvents, and can also be suspended in emulsions. These natural cannabinoids are concentrated in a viscous resin that is produced in glandular structures known as trichomes. In addition to cannabinoids, the resin is rich in terpenes, which are largely responsible for the odor of the cannabis plant. These materials are also present in additional tissues of the plant, most notably in the flowers and leaves of the plants.
- Cannabinoid research has increased tremendously in recent years since the discovery of cannabinoid receptors and the endogenous ligands for these receptors.
- the receptors include CB1, predominantly expressed in the brain, and CB2, primarily found on the cells of the immune system.
- Cannabinoid receptors belong to a superfamily of G protein- coupled receptors. They are single polypeptides with seven transmembrane a-helices, and have an extracellular, glycosylated N-terminus and intracellular C-terminus. Both CB1 and CB2 cannabinoid receptors are linked to Gl/0 proteins.
- ligands for these receptors capable of mimicking the pharmacological actions of THC have also been discovered.
- Such ligands were designated endocannabinoids and included anandamide and 2-arachidonoyl glycerol (2-AG).
- Anandamide is produced in the brain and peripheral immune tissues such as the spleen.
- cannabidiol Unlike THC, which exerts its action by binding to CB1 and CB2, cannabidiol (CBD) does not readily bind to these receptors and hence has no psychotropic activity. Instead, cannabidiol indirectly stimulates endogenous cannabinoid signaling by suppressing the enzyme that breaks down anandamide (fatty acid amide hydroxylase,“FAAH”). Cannabidiol also stimulates the release of 2-AG. Cannabidiol has been reported to have immunomodulating and anti-inflammatory properties; to exhibit anticonvulsive, antianxiety, and antipsychotic activity; and to function as an efficient neuroprotective antioxidant.
- FAAH fatty acid amide hydroxylase
- Cannabinoids in cannabis are often inhaled via smoking but may also be ingested.
- Smoked or inhaled cannabinoids have reported bioavailabilities ranging from 2-56%, with an average of about 30% (Huestis (2007) Chem. Biodivers. 4: 1770-1804; McGilveray (2005) Pain Res. Manag. 10 Suppl. A: 15A-22A). This variability is mainly due to differences in smoking dynamics.
- Cannabinoids that are absorbed through the mucous membranes in the mouth have bioavailabilities of around 13% (Karschner et al. (2011) Clin. Chem. 57:66-75).
- CBD is generally considered to be safe and has been used medicinally and in nutraceutical applications. The mechanism of action of CBD is multifold.
- CB1 and CB2 receptors Two cannabinoid receptors are known to exist in the human body, including CB1 and CB2 receptors, but THC, and not CBD, binds to these receptors.
- the CB1 receptors are located mainly in the brain and modulate neurotransmitter release in a manner that prevents excessive neuronal activity.
- the modulation of these neurotransmitters may be implicated in the calming effect and reduction in anxiety that is defined by CBD.
- CBD also has the ability to regulate and reduce pain; reduce inflammation; and regulate movement, sensory perception, and cognitive function.
- An endogenous ligand, anandamide which is naturally occurring in the human body, binds to the CB1 receptor though the G protein coupling system.
- CBD has an indirect effect on the CB1 receptor by stopping the enzymatic breakdown of anandamide, allowing it to stay in the system longer and thus providing certain benefits.
- CBD has a mild effect on the CB2 receptors, which are located in the periphery in lymphoid tissue. Accordingly, CBD helps to mediate the release of cytokines from immune cells in a manner that helps to reduce inflammation and pain. Indeed, cannabinoids such as CBD also induce apoptosis and inhibit cell proliferation, in addition to the suppression of cytokine production, while also inducing regulatory T cells (Tregs).
- cannabinoids such as CBD also induce apoptosis and inhibit cell proliferation, in addition to the suppression of cytokine production, while also inducing regulatory T cells (Tregs).
- CBD can protect certain cells, for example within the central nervous system, from certain autoimmune conditions such as MS.
- CBD also plays a modulation role.
- Cytokines are signaling proteins synthesized and secreted by immune cells upon stimulation. These factors balance the initiation and resolution of inflammation. Accordingly, one of the possible mechanisms of immune control by CBD is by perturbing the balance between cytokines produced by T helper subsets, Thl and Th2. In certain prior studies, both anti-inflammatory and proinflammatory effects were shown.
- THC During chronic inflammation, IL-6 suppression can decrease tissue injury.
- THC has been shown to decrease IL-6, TNFa, GM-CSF, and IFNy. Accordingly, THC may be a necessary component in certain applications when a combined effect is necessary to reduce inflammation and decrease pain. Low doses of THC may be suitable to provide these therapeutic effects.
- CBD is also known to stimulate vanilloid pain receptors (TRPV-1 receptor), which are known to mediate pain perception, inflammation, and body temperature. CBD may also impact certain adenosine receptors, which play a significant role in cardiovascular function and broadly impact anti-inflammatory effects throughout the body as well as regulate and decrease anxiety and depression and increase the sense of well-being.
- TRPV-1 receptor vanilloid pain receptors
- Generating THC as a pure compound is performed by extracting the compound from green material from the cannabis plant, typically leaves, flowers, and buds. However, in the extraction process, a number of other cannabinoid compounds are also extracted, and there are at least 85 different cannabinoids that have been isolated from the plant, and some have reported 483 identifiable chemical constituents known to exist in the cannabis plant.
- Terpenes are a large class of organic compounds produced by a wide number of plants including conifers and other leafy plants, such as cannabis. The chemicals often have a strong and readily identifiable odor. Terpenes are the primary constituent of many essential oils of many types of plants and flowers, typically used for their aromatic boutique, but also for their medicinal properties.
- Applicant has advantageously identified that therapeutic properties are enhanced through selective inclusion of certain terpene compounds admixed into a pharmaceutical composition with CBD. Specifically, it is advantageous to admix b-caryophyllene and Linalool in concentrations much greater than found in typical full spectrum extracts. Accordingly, it would be advantageous to add in these molecules as individualized and specific extracts in order to reach about 2% total weight of the formulation for each of the b-caryophyllene and Linalool. The inclusion of these terpene molecules increases the bioavailability of the CBD, as well as targets certain receptors in the body to impact pain, inflammation, and anxiety. These are particularly important in the wholistic treatment of opioid use disorder.
- Curcumin is derived from the Curcuma longa plant and is the principal curcuminoid of turmeric, a member of the ginger family Zingiberaceae . Curcumin is widely panned as a molecule that shows positive results in drug screening but leads to undue experimental attention while failing to advance as a viable drug or drug lead.
- Curcumin when admixed with certain other molecules, can lead to surprising synergistic effects, specifically when used with cannabinoids such as THC or specifically with CBD, and also with certain terpenes or terpenes mixed with CBD. Accordingly, an inclusion of between 1% and 10% by weight of curcumin to a composition as described herein can increase certain therapeutic effects.
- Curcumin has certain medicinal properties, including with regard to pain relief and reduction in inflammation. Unlike analgesic drugs, curcumin does not neutralize the pain sensation for a few hours. Instead, curcumin impacts pain sensation by reduction in
- inflammation which in turn reduces impacts on the body that are causing pain. Accordingly, the reduction in inflammation is also helpful as an antiarthritic agent and for osteoarthritis.
- Cannabinoid compounds of the present disclosure are highly lipophilic, meaning that they are soluble in lipids and some organic solvents while being substantially insoluble or only sparsely soluble in water.
- the poor water solubility of these lipophilic agents often results in major difficulties in formulation.
- lipophilic compounds When administered in the form of an oil solution or some kind of water and/or oil suspension or emulsion, lipophilic compounds usually show poor bioavailability.
- micellar solubilization by means of surface-active agents (i.e., the use of surfactant micelles to solubilize and transport the therapeutic agent).
- micelles can incorporate lipophilic therapeutic agents in the hydrocarbon core of the micelle or can entangle the agents at various positions within the micelle walls.
- formulations is limited by the solubility of the therapeutic agent in the micelle surfactant. For many lipophilic therapeutic agents, such solubility is too low to offer formulations that can deliver therapeutically effective doses.
- Another method consists of preparing a derivative or an analog of the lipophilic compound having a better solubility in water than the original compound.
- this derivative may be a water-soluble salt of the compound that usually retains the original biological activity.
- this approach is applicable only to compounds having acidic or basic properties. If more substantial modifications are introduced into the original compound to improve its solubility, a decrease or even a complete loss of the original bioactivity of the compound is frequently observed.
- Another approach consists of preparing a water-soluble prodrug capable of liberating the original bioactive compound under physiological conditions.
- prodrugs usually improve bioavailability of the compound and can ensure a targeted delivery of the compound or its sustained release over a period of time.
- the use of prodrugs is not universally applicable since they usually require the presence of certain functional groups in the original compound.
- synthetic methods of improving solubility of a compound by chemical modifications are relatively complicated and expensive.
- chelating agents such as citric acid, tartaric acid, amino acids, thioglycolic acid, and edetate disodium.
- buffering agents such as acetate, citrate, glutamate, and phosphate salts.
- buffers and chelating agents have been implicated in imparting high levels of aluminum in products, leading to adverse side effects.
- certain chelating agents such as EDTA have been implicated in adverse events such nephrotoxicity and renal tubular necrosis.
- colloids examples include polypeptides (such as gelatin, casein, and caseinate), polysaccharides (such as starch, dextrin, dextran, pectin, and gum arabic), as well as whole milk, skimmed milk, milk powder, or mixtures of these.
- polyvinyl alcohol and vinyl polymers for example polyvinylpyrrolidone, (meth)acrylic acid polymers and copolymers, methylcellulose, carboxymethylcellulose, hydroxypropyl cellulose, and alginates.
- the cannabinoid compounds of the present embodiments are known to those of ordinary skill in the art to have a reduced bioavailability when taken orally by a mammal.
- Increasing bioavailability is a key issue as it allows a reduction in the total lipophilic agents, while either maintaining the total concentration of the agents within the body or blood stream, or allows for a total increase in the blood plasma concentration levels within the body.
- Preventing first-pass metabolism, increasing the rate of uptake, or both will increase the bioavailability of the cannabinoids and terpene molecules of the present formulations.
- Oral administration constitutes the preferred route of administration for a majority of drugs.
- the less than 10% oral bioavailability of the CBD compound provides a dead end approach toward treatment as the quantity of the CBD necessary to achieve therapeutic levels typically also generates significant GI issues.
- certain cannabinoids, including CBD have a bitter taste that leads to lack of patient compliance in the case of orally administered dosage forms. In such cases, taste masking is an essential tool to improve patient compliance.
- compositions also comprise one or more lipophilic active agents which may include but are not limited to dry milk, menthol, sweeteners, sodium bicarbonate, ion-exchange resins, cyclodextrin inclusion compounds, adsorbates, and the like.

- Lyophilization also known as freeze-drying, is a process whereby water is sublimed from a composition after it is frozen. The frozen solution is then typically subjected to a primary drying step in which the temperature is gradually raised under vacuum in a drying chamber to remove most of the water, and then to a secondary drying step typically at a higher temperature than employed in the primary drying step to remove the residual moisture in the lyophilized composition. The lyophilized composition is then appropriately sealed and stored for later use. Tang et al. (2004) Pharmaceutical Research 21 : 191-200 describes the scientific principles pertaining to freeze-drying and guidelines for designing suitable freeze- drying processes. Further description of freeze-drying is found in Remington (2006) The Science and Practice of Pharmacy, 21st edition, Lippincott, Williams, & Wilkins, pp. 828-831.
