  • Composition for inhalation comprising delta-9-tetrahydrocannabinol in a semiaqueous solvent
    Patent number: 7648696
    Abstract: A stable composition for rapid delivery by inhalation to the lungs, and subsequently to the bloodstream, is provided. The composition comprises a therapeutically effective amount of delta-9-tetrahydrocannabinol in a pharmaceutically-acceptable semiaqueous solvent comprising an alcohol, water and a glycol. A composition comprising volumetric ratios of ethanol:water:propylene glycol selected from those in the range of from 10-70:10-30:20-80, respectively, having a combined total of 100 is also provided. A sterile and/or preserved sealed unit-or multi-unit dosage form of delta-9-tetrahydrocannabinol is further provided.

  • Stable composition for inhalation therapy comprising delta-9-tetrahydrocannabinol and semiaqueous solvent therefor
    Patent number: 6747058
    Abstract: A formulation of delta-9-tetrahydrocannabinol in a semi-aqueous solvent, such as 35:10:55 alcohol:water:propylene glycol (v/v), produces a stable clear solution near the solubility point of the drug. Because delta-9-tetrahydrocannabinol has poor affinity for the formulation, it is able to partition out and transport across cell membranes to reach the bloodstream quickly. This has been demonstrated by the comparative tmax values achieved in single dose intravenous and 14 day multiple dose inhalation studies conducted in dogs and rats.
