Abstract
A pharmaceutical composition which reduces or eliminates the drug abuse potential of central nervous system stimulant comprising: (a) a drug selected from the group consisting of methylphenidate, amphetamine, methamphetamine, and combinations thereof; and (b) a gel forming polymer wherein the gel forming polymer is a polymer that forms a gel when contacted with moisture or placed in an aqueous solution. The present invention is based on the discovery that a central nervous system stimulant such as methylphenidate in combination with a gel forming polymer reduces or eliminates drug abuse potential by swelling in the presence of moisture, and thus, preventing nasal absorption and injectability of the drug.
