呋喃苯胺酸缓释片的溶出试验及其药效学研究
DISSOLUTION TEST IN VITRO AND PHARMACO-DYNAMIC STUDIES ON SUSTAINED RELEASE TABLET OF FUROSEMIDE
-
摘要: 呋喃苯胺酸缓释片在人工胃液中2小时的累积释放率由普通呋喃苯胺酸片的23%降低至4%,而在人工肠液中100%释放时间则由10分钟延长至8小时。药效学试验的结果表明,普通片与缓释片的总利尿量相仿,但缓释片平稳持久地维持较适宜的利尿作用,时间延长至9小时左右,且降低了普通片所致的毒副作用。Abstract: Based on the theories of orthogonal design and by means of pharma- ceutical technology a sustained release tablet of furosemide was designed. By comparison with conventional tablets,the dissolution ratio in 2 h period in simulated gastric liquid was reduc
