The invention relates to compositions for sublingual and/or buccal administration comprising at least one cannabinoid or cannabinoid extract, triglyceride, alcohol, and at least one surfactant.
The medicinal and psychoactive properties of the cannabis plant have been known for centuries. While it has been illegal in many countries, there is a growing populous to lobby for legalization of its use, especially for medicinal purposes.
Cannabis is believed to provide benefits in the treatment of multiple disorders with safer and fewer serious side effects than most prescription drugs currently used as antiemetics, muscle relaxants, hypnotics and analgesics. A disadvantage in treating patients with cannabis is the psychoactive effect, especially in “naive” cannabis users. Furthermore, there have been reports of unpleasant reactions to cannabis, such as anxiety, panic or hallucinations. It is believed that the undesirable side effects are most commonly associated with higher doses of cannabis and are related to the difficulty in controlling the dosage when the drug is smoked or eaten in cannabis-enriched confectionaries.
Cannabis has also been used to treat the symptoms in patients suffering from serious medical conditions. For example, cannabis has been used to alleviate symptoms associated with cancer, anorexia, AIDS, chronic pain, muscle spasticity, glaucoma, arthritis, migraine and many other illnesses. Cannabis is recognized as having anti-emetic properties and has been successfully used to treat nausea and vomiting in cancer patients undergoing chemotherapy. Cannabis has also been reported in treating the weight loss syndrome of AIDS and for the treatment of glaucoma by reducing intraocular pressure. Cannabis is also known for it muscle relaxing and anti-convulsant effects.
The most prevalent mode of administration of medical cannabis is by smoking. This mode of administration can have adverse effects on the lungs. Cannabis smoke carries more tar and other particulate matter than tobacco and may be a cause of lung diseases including lung cancer. Furthermore, many patients find the act of smoking unappealing, as well as generally unhealthy.
Accordingly, there is significant interest in developing other means to administer cannabis to patients.
Absorption of drugs from the oral cavity into the mucosal tissues is typically a fast event. Dissolved drugs partition into the mucosal membranes and within minutes will reach equilibrium with drug in solution in the oral cavity. However, this does not always equate to rapid drug appearance in the systemic circulation. This has been attributed to slow partitioning out of the mucosal tissues and into the systemic circulation. The principle barrier is the stratum corneum and one of the strategies that have been found to promote cutaneous drug penetration is through the use of absorption enhancers. A variety of solvents have been identified as “absorption enhancers”. The extraction of lipids with the formation of “pores” within the stratum corneum, thus increasing cutaneous hydration and solubility of the solute are general action mechanisms which have been suggested to explain the enhancing action of these substances. The transport of non-polar materials, such as the cannabinoids, may be increased through the addition of small quantities of fatty acids or alcohols within the products formulation. The addition of small quantities of alcohol produces a significant increase in the flow of drug through the skin, being that the longer the lateral carbon chain, this being up to a length of 14 carbon atoms, the greater is the enhancing effect produced.
Current marketed tinctures that contain decarboxylated cannabis plant material exist as oil-based tinctures or alcohol-based tinctures. Emulsions are mixtures of two or more liquids in which one is present as droplets, of microscopic or ultramicroscopic size, distributed throughout the other. Emulsions are formed from the component liquids either spontaneously or, more often, by mechanical means, such as agitation, provided that the liquids that are mixed have no mutual solubility. Emulsions are stabilized by agents that form films at the surface of the droplets or that impart to them a mechanical stability. Unstable emulsions eventually separate into two liquid layers.
In oil-ethanol emulsions, ethanol is the polar phase and oil is the nonpolar phase. The primary advantage of oil-ethanol emulsions over conventional water-oil emulsions is that they enable the incorporation of water-and oil-insoluble or poorly soluble functional compounds and/or drugs into emulsions. A non-ionic surfactant was used to stabilize the oil-ethanol emulsion.
In the past, oil and alcohol have been combined in the presence of various emulsifiers to produce an emulsion, but the results have been unsatisfactory. The oil phase separated out of the mixture after relatively short periods of time indicating an unstable emulsion.

Surfactants are important excipients frequently used as stabilizers and solubilizers. There are many commercially available surfactants. They have different properties and the same surfactant may have a wide range of applications. The pharmaceutical surfactants lecithin; phosphadylcholine fractions, poloxamer, sodium cholate and polysorbate 80 are well tolerated and non-toxic. They are unlikely to induce allergic reactions, hypersensitivity or cytokine production.
Lecithin is a naturally occurring mixture of the diglycerides of stearic, palmitic, and oleic acids, linked to the choline ester of phosphoric acid, commonly called phosphatidylcholine. Hydrogenated Lecithin is the product of controlled hydrogenation of Lecithin. Bilayers of these phospholipids in water may form liposomes, a spherical structure in which the acyl chains are inside and not exposed to the aqueous phase. Lecithin and Hydrogenated Lecithin are used in a large number of cosmetic formulations as skin conditioning agents-miscellaneous and as surfactant-emulsifying agents. Hydrogenated Lecithin is also used as a nonsurfactant suspending agent. Lecithin is virtually nontoxic in acute oral studies, short-term oral studies, and subchronic dermal studies in animals. Lecithin is not a reproductive toxicant, nor is it mutagenic in several assays. Fiume Z. Int J Toxicol. 2001; 20 Suppl 1:21-45.
Soy lecithin one of the most widely used food additives on the market today. It is used as an emulsifier. It helps to emulsify numerous foods, even unlikely emulsions such as chocolate. In chocolate, lecithin stabilizes the cocoa butter fat so it doesn't separate from the moisture, cocoa solids and dairy.

The compositions disclosed herein include a composition for daily administration. In some embodiments, the therapeutic effect is maintained with one administration, twice daily. The duration of each dose's effect is between four (4) to six (6) hours.
In certain aspects, the present invention is directed to a method of sublingually or buccally administering a therapeutic agent to a patient, comprising the steps of: a) preparing a pharmaceutical composition as defined herein, and b) administering the pharmaceutical composition to the underside of the tongue of the patient. In certain embodiments, the pharmaceutical composition is a liquid.
In other aspects, the present invention is directed to a method for treating a disease comprising administering a daily therapeutically effective amount of the pharmaceutical composition as described herein or the dosage form as described herein.
Actual dosage levels of the active ingredients in the pharmaceutical compositions may be varied so as to obtain an amount of the active ingredient that is effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration, without being toxic to the patient.
The selected dosage level will depend upon a variety of factors including the activity of the particular compound or combination of compounds employed, or the ester, salt or amide thereof, the route of administration, the time of administration, the rate of excretion of the particular compound(s) being employed, the duration of the treatment, other drugs, compounds and/or materials used in combination with the particular compound(s) employed, the age, sex, weight, condition, general health and prior medical history of the patient being treated, and like factors well known in the medical arts.
A physician or veterinarian having ordinary skill in the art can readily determine and prescribe the therapeutically effective amount of the pharmaceutical composition required. For example, the physician or veterinarian could start doses of the pharmaceutical composition or compound at levels lower than that required in order to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved. In some embodiments, by “therapeutically effective amount” is meant the concentration of a compound that is sufficient to elicit the desired therapeutic effect. It is generally understood that the effective amount of the compound will vary according to the weight, sex, age, and medical history of the subject. Other factors which influence the effective amount may include, but are not limited to, the severity of the patient's condition, the disorder being treated, the stability of the compound, and, if desired, another type of therapeutic agent being administered with the compound of the invention. A larger total dose can be delivered by multiple administrations of the agent. Methods to determine efficacy and dosage are known to those skilled in the art (Isselbacher et al. (1996) Harrison's Principles of Internal Medicine 13 ed., 1814-1882, herein incorporated by reference).
In general, a suitable daily dose of an active compound used in the compositions and methods of the invention will be that amount of the compound that is the lowest dose effective to produce a therapeutic effect. Such an effective dose will generally depend upon the factors described above.
If desired, the effective daily dose of the active compound may be administered as one, two, three, four, five, six or more sub-doses administered separately at appropriate intervals throughout the day, optionally, in unit dosage forms. In certain embodiments of the present invention, the active compound may be administered two or three times daily. In preferred embodiments, the active compound will be administered once daily.

Representative samples of the pharmaceutical formulations in tinctures were diluted/dissolved with organic solvents. A portion of formulation, typically from 10 to 1200 mg, were weighed into a 50-mL centrifuge tube. The amount weighed depended upon the specific product and the declared concentrations of cannabinoids. A Surrogate Standard (SUR) (a pure analyte, which should not be found in any sample, but is similar in nature to the compounds of interest) and 20.0-mL of methanol (MeOH) were added. The solution was mixed well and was either diluted further or used directly for analysis. If necessary, this extract was diluted an additional 2- to 20-fold based on the concentrations of cannabinoids in the sample. The internal standard working diluent (IWD) (a solution of internal standard that is prepared from the internal standard stock diluent and added to all samples at the same concentration) was then added to the extract or dilution thereof, and the potency measurement was made using HPLC-PDA.
The diluted samples fortified with internal standard were injected onto an HPLC. The targeted analytes were separated and subsequently detected online by monitoring UV absorbance using a PDA detector. The separation of ten cannabinoids was achieved on a C18 reverse-phase column 150 mm in length. The limit of quantification for most of the cannabinoids was approximately 0.60 i.t.g/mL. This method was used to quantify the cannabinoid components that are present as low as 0.04% (percent by weight) in the formulations.
