Abstract
A compressible pharmaceutical composition comprising a cannabinoid and at least one excipient is disclosed. The composition may be an intermediate used in the manufacture of compressible dosage forms of cannabinoids such as tablets. The cannabinoid may be CBD or THC. The compressible excipient may be a material such as microcrystalline cellulose or lactose, or a matrix forming polymer such as a polyvinylpyrrolidone-vinyl acetate copolymer; a polyvinylcaprolactam, polyvinyl acetate, and polyethylene glycol 6000 copolymer; and an ethylene oxide and propylene oxide copolymer. Also disclosed are dry granulation processes for manufacturing the inventive composition, including slugging, roller compaction, hot-melt extrusion, and melt granulation.
Claims23
A compressible pharmaceutical composition comprising a cannabinoid and at least one excipient wherein the composition is formed without the use of a solvent, wherein the cannabinoid loading comprises 25%-90% w/w of the composition, and wherein the excipient is a compressible pharmaceutical binder, and wherein the composition is a dry powder of 20 mesh or smaller particle size.

A process for the preparation of a compressible pharmaceutical composition, comprising the steps of:
- a. Mixing a dry powdered cannabinoid with magnesium stearate and a binding excipient in a blender for 5-30 minutes to form a uniform mixed blend;
- b. Slugging the uniformly mixed blend in a tablet press using 7-20 mm punches with 5-30 kN compression pressure to form slugs;
- c. Breaking the slugs with an oscillating mill equipped with 12-mesh screen;
- d. Passing the granulation through a 20-mesh screen using an oscillating mill to obtain a 20-mesh granulate;
- and
- e. wherein the total weight percent of the cannabinoid is 25-90% w/w of the granulate.
(canceled)
A process for the preparation of a compressible pharmaceutical composition, the process comprising the steps of:
- a. Mixing 75.00% by weight of dry powdered cannabidiol with 0.50% by weight of Magnesium Stearate and 24.500% by weight of a binding excipient in a twin shell blender for at least 5 minutes;
- b. Slugging the uniformly mixed blend in a tablet press using 10 mm flat face punches with 20 kN compression pressure;
- c. Breaking the slugs with an oscillating mill equipped with 12-mesh screen;
- d. Passing the granulation through a 20-mesh screen using an oscillating mill to obtain a 20-mesh granulate.
(canceled)
A process for the preparation of a compressible pharmaceutical composition, comprising the steps of:
- a. Mixing a dry powdered cannabinoid with magnesium stearate and a binding excipient in a blender for 5-30 minutes to form a uniform mixed blend;
- b. compacting the uniform mixed blend in a roller compacter with 5-30 kN pressure to form a ribbon;
- c. Breaking the ribbon with an oscillating mill equipped with 20-mesh screen to obtain a 20-mesh granulate;
- and
- d. wherein the total weight percent of the cannabinoid is 25-90% w/w of the granulate.
