The present invention is directed to a composition that can be used to deliver an antipsychotic drug such as risperidone, paliperidone or a combination thereof, as an injectable in-situ forming biodegradable implant for extended release providing therapeutic plasma levels from the first day. The composition is in the form of drug suspension on a biodegradable and biocompatible copolymer or copolymers solution using water miscible solvents that is administered in liquid form. Once the composition contacts the body fluids, the polymer matrix hardens retaining the drug, forming a solid or semisolid implant that releases the drug in a continuous manner. Therapeutic plasma levels of the drug can be achieved from the first day up to at least 14 days or more even up to at least four weeks.
本发明涉及一种组合物,该组合物可用于递送抗精神病药物,如利培酮、帕利培酮或其组合物,作为可注射的原位形成生物可降解植入物,用于延长释放,从第一天起提供治疗血浆水平。该组合物以药物悬浮液的形式存在于可生物降解的生物相容性共聚物或共聚物溶液中,使用水溶性溶剂,以液态形式给药。一旦组合物与体液接触,聚合物基质就会硬化,将药物保留下来,形成固体或半固体植入物,以连续的方式释放药物。药物的治疗血浆水平可从第一天开始达到至少 14 天,甚至至少四周。
