巴尼地平或其生理上可接受的盐双层渗透泵控释药物组合物制造技术

本发明专利技术公开了一种巴尼地平或其生理上可接受的盐双层渗透泵控释药物组合物，它包括由有双层片芯和包衣膜组成，双层片芯内含有有效剂量的巴尼地平或其生理上可接受的盐和药学上可接受的药用辅料，包衣膜为含或不含制孔剂的半透膜。本发明专利技术制备的巴尼地平或其生理上可接受的盐双层渗透泵控释药物组合物，能有效地控制药物在特定时间内释放，减少服药次数，体内血药浓度平稳，从而保证了患者服药期间体内血药浓度平稳而有效，从根本上提高了药物的安全性和有效性和患者的顺应性。

Nicardipine or its physiologically acceptable salt bilayer osmotic pump controlled release drug composition

The invention discloses a double salt osmotic pump barnidipine or physiologically acceptable controlled-release pharmaceutical composition, it comprises a double tablet core and coating, pharmaceutical excipients double-layer tablet core contains effective dose of barnidipine or physiologically acceptable salts and pharmaceutically acceptable coating. The film is a semi permeable membrane containing hole making agent. Double salt osmotic pump prepared by the invention of barnidipine or physiologically acceptable controlled-release drug composition, can effectively control the drug release in a certain period of time, reduce the frequency of administration, the blood concentration in vivo is stable, so as to ensure patient medication during blood concentration in vivo is stable and effective, and fundamentally improve the adaptation of the safety and efficacy of drugs and patients.
