Chewable drug-delivery compositions and methods for preparing the same
First Claim
1. A non-aqueous process for preparing non-aqueous, chewable composition for oral delivery of unpalatable drugs, comprising a therapeutically-effective amount of one or more unpalatable drugs intimately dispersed or dissolved in a pharmaceutically-acceptable lipid which is a solid at ambient temperature, or a mixture of said lipids, the method comprising:
- (a) providing a therapeutically-effective amount of one or more unpalatable drugs and a pharmaceutically-acceptable molten lipid;
(b) feeding said drug and molten lipid into a fluidized bed apparatus comprising means for fluidizing said drug and lipid; and
(c) fluidizing said drug and lipid in said fluidized bed apparatus in the absence of a solvent for a time sufficient to solidify the molten lipid and drug into particles comprising said drug and lipid, wherein said particles have a number average particle size of from 10-150 microns,wherein said drug is present in an amount of from about 0.1-75 weight percent of said composition and said lipid is present in an amount of from about 5-50 weight percent of said composition.

Abstract
A non-aqueous, chewable composition for oral delivery of unpalatable drugs is provided along with preparative methods therefor. The composition contains the drug intimately dispersed or dissolved in a pharmaceutically-acceptable lipid that is solid at room temperatures. The composition also has a matrix that contains a granulating agent for the total composition and a rapid dispersal agent and optionally additives such as buffering agents, flavoring agents, surfactants, and the like.

5. A non-aqueous process for preparing a non-aqueous, chewable composition for oral delivery of unpalatable drugs, comprising a therapeutically-effective amount of one or more unpalatable drugs dissolved in a pharmaceutically-acceptable lipid which is a solid at ambient temperature, or a mixture of said lipids, the method comprising:
-
(a) providing a molten mixture of a therapeutically-effective amount of one or more unpalatable drugs in its molten state with a pharmaceutically-acceptable lipid in its molten state in the absence of a solvent; and (b) solidifying the molten drug and lipid mixture by contacting the molten mixture with air into particles comprising said drug and lipid, wherein said drug is present in an amount of from about 0.1-75 weight percent of said composition and said lipid is present in an amount of from about 5-50 weight percent of said composition. - View Dependent Claims (6, 7, 8, 14, 15, 16, 17)
