Abstract
Official abstract text for this publication.
A composition comprising a high purity cannabinoid, an acid, and a pharmaceutically-acceptable solvent achieves room temperature stability for over 24 months. The acid improves the stability of the composition and the solvent enhances the solubility of the acid, thereby allowing the acid to have an improved stabilizing effect on the highly pure cannabinoid. Preferably, the solvent is an alcohol and, more preferably, the composition contains an oil. A method for making the composition includes combining the cannabinoid and the solvent and evaporating a portion of the solvent, along with adding an acid to the composition, before, during, or after the evaporating step. A method for making and storing the composition includes storing the composition in a manner adapted to maintain its stability. Pharmaceutical dosage forms include a formulated composition, such as having the oil. A method of treating a subject comprises administering to the subject the dosage form.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising a cannabinoid, an acid, an oil, and a pharmaceutically-acceptable solvent in a concentration of between about 0.001% by weight and about 2% by weight, wherein the solvent comprises a C 1 -C 4 alcohol, the acid is sufficiently soluble in the solvent to provide an amount of dissolved acid in the solvent which improves the stability of the composition and the composition is in liquid form. 2. The composition of…
