The present invention relates to a composition comprising pharmaceutical active ingredients which are susceptible to, or have potential for, abuse. The invention provides an oral pharmaceutical composition comprising a first population of beads and a second population of beads. The first bead population comprises a pharmaceutically active ingredient susceptible to, or having the potential for, abuse. The second bead population comprises a gelling agent and a coating substantially surrounding the gelling agent, but containing no pharmaceutically active ingredient. The first bead population and the second bead population are physically separable, but visually indistinguishable to the naked eye. Upon ingress of water into the second population of beads, the gelling agent is caused to swell forming a viscous mass inhibiting or preventing the extraction of the active ingredient.
本发明涉及一种由药物活性成分组成的组合物,这些活性成分易被滥用或有可能被滥用。本发明提供了一种口服药物组合物,该组合物由第一珠群和第二珠群组成。第一珠群包括易被滥用或有可能被滥用的药物活性成分。第二珠群包括胶凝剂和基本围绕胶凝剂的涂层,但不含药用活性成分。第一珠群和第二珠群在物理上可以分离,但肉眼无法分辨。当
水进入第二珠群时,胶凝剂会膨胀形成粘性物质,从而抑制或阻止活性成分的提取。
