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.
一种药物组合物,用于减少或消除中枢神经系统兴奋剂的药物滥用潜力,包括:(a)从甲基苯丙胺、安非他命、甲基安非他命和其组合中选择的药物;和(b)凝胶形成聚合物,其中凝胶形成聚合物是一种在接触到水分或置于水溶液中时形成凝胶的聚合物。本发明基于这样的发现:中枢神经系统兴奋剂,如甲基苯丙胺与凝胶形成聚合物的组合,通过在水分存在下肿胀,从而防止药物被鼻腔吸收和注射,从而减少或消除了药物滥用潜力。
