Patent Application
20220000764
The invention relates to a composition suitable for use in a personal vaporizer, comprising an oil soluble liquid emulsifier base and an extract, wherein the extract comprises a cannabinoid and a terpene, to methods of administering such compositions to a subject, and to related kits.
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 its 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.
Cannabinoids and other active agents also can be administered in liquid compositions formulated for personal vaporizers—devices that typically utilize a small battery-powered atomizer or heater to turn a liquid into a vapor so that a subject can inhale the vapor. Many personal vaporizers are relatively small and inherently portable and come in a variety of forms. Personal vaporizers can be filled with liquid compositions to be vaporized. Such liquid compositions generally include one or more liquid bases in conjunction with the active drug to be administered. When a solution of liquid base is mixed and heated, the vapor becomes infused with the active ingredient, taking on a variety of therapeutic uses. Typical personal vaporizer liquid bases include propylene glycol, glycerol, or PEG-400 and they are primarily intended to function with the addition of water-soluble additives. Typical known bases such as these are inadequate, however, in that they are unable to emulsify oil-soluble compounds and/or resins for use in a personal vaporizer.
There remains a need in the art, therefore, for an improved non-water soluble personal vaporizer liquid base for the emulsion of oil-soluble compounds.
In one aspect, the invention provides a composition suitable for use in a personal vaporizer, comprising: an oil soluble liquid emulsifier base; and an extract, wherein the extract comprises a cannabinoid and a terpene.
In another aspect, the invention provides a method of treating a condition in a subject, comprising administering to the subject a composition suitable for use in a personal vaporizer, the composition comprising an oil soluble liquid emulsifier base and an extract, wherein the extract comprises a cannabinoid and a terpene, e.g., in an amount effective to treat the condition.
In another aspect, the invention provides a kit for administering a composition suitable for use in a personal vaporizer, the kit comprising: a composition comprising an oil soluble liquid emulsifier base and an extract, wherein the extract comprises a cannabinoid and a terpene; a personal vaporizer; and instructions for the use of said kit.

The formulations may conveniently be presented in unit dosage form and may be prepared by any methods well known in the art of pharmacy. The amount of active ingredient which can be combined with a carrier material to produce a single dosage form will vary depending upon the host being treated, the particular mode of administration. The amount of active ingredient that can be combined with a carrier material to produce a single dosage form will generally be that amount of the compound which produces a therapeutic effect. Generally, out of one hundred percent, this amount will range from about 1 percent to about ninety-nine percent of active ingredient, preferably from about 5 percent to about 70 percent, most preferably from about 10 percent to about 30 percent.
Methods of preparing these formulations or compositions include the step of bringing into association an active compound, such as a compound of the invention, with the carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association a compound of the present invention with liquid carriers, or finely divided solid carriers, or both, and then, if necessary, shaping the product.
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. 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.
A “therapeutically effective amount” or a “therapeutically effective dose” of a drug or agent is an amount of a drug or an agent that, when administered to a subject will have the intended therapeutic effect. The full therapeutic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses. Thus, a therapeutically effective amount may be administered in one or more administrations. The precise effective amount needed for a subject will depend upon, for example, the subject's size, health and age, and the nature and extent of the condition being treated, such as cancer or MDS. The skilled worker can readily determine the effective amount for a given situation by routine experimentation.
In certain embodiments, the condition is selected from the group consisting of pain associated with cancer, neuropathic pain, HIV-associated sensory neuropathy, side effects of chemotherapy, symptoms of neurology or a neurodegenerative disease, cancer, hepatitis C, methicillin-resistant Staphylococcus aureus (MRSA), pruritus, psoriasis, asthma, sickle-cell disease, sleep apnea, a digestive disease, collagen-induced arthritis, atherosclerosis and dystonia.

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.
Tables 2-6 show the cannabinoid profile for compositions suitable for use in a personal vaporizer and containing two cannabinoids in a ratio of 20:1 THC to CBD by weight.
Tables 7-12 show the cannabinoid profile for compositions suitable for use in a personal vaporizer and containing two cannabinoids in a ratio of 1:1 THC to CBD by weight.
Tables 13-16 show the cannabinoid profile for compositions suitable for use in a personal vaporizer and containing two cannabinoids in a ratio of 1:20 THC to CBD by weight.
