The present invention is directed to a buprenorphine sustained release delivery system capable of delivering buprenorphine, a metabolite, or a prodrug thereof for a duration of about 14 days to about 3 months. The buprenorphine sustained release delivery system includes a flowable composition and a solid implant for the sustained release of buprenorphine, a metabolite, or a prodrug thereof. The implant is produced from the flowable composition. The buprenorphine sustained release delivery system provides in situ 1-month and 3-month release profiles characterized by an exceptionally high bioavailability and minimal risk of permanent tissue damage and typically no risk of muscle necrosis.
本发明涉及一种丁丙诺啡缓释给药系统,该系统能够在约14天至约3个月的时间内给药丁丙诺啡、其代谢物或原药。丁丙诺啡持续释放给药系统包括可流动组合物和固体植入物,用于持续释放丁丙诺啡、其代谢物或原药。植入物由可流动组合物制成。丁丙诺啡持续释放给药系统可提供 1 个月和 3 个月的原位释放曲线,其特点是
生物利用度极高,永久性组织损伤的风险极小,通常没有肌肉坏死的风险。
