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,可减少或消除中枢神经系统兴奋剂的滥用潜力,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)一种形成凝胶的聚合物,其中形成凝胶的聚合物是在接触
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
丙胺与形成凝胶的聚合物的组合,通过在
水分存在时肿胀,从而防止药物经鼻吸收和注射,从而减少或消除药物滥用潜力。
