摘要: 制备曲马多药物树脂缓释混悬剂，以市售普通胶囊剂为对照，研究了缓释混悬剂的药物动力学和生物利用度。采用ＨＰＬＣ法测定两制剂血药浓度，结果表明，４种健康志愿者单剂量口服缓释混悬剂１０ｍｌ一，达峰时间明显后移，峰浓度显著降低，以血药浓度经时曲线下面积计算相对生物利用度为１０３．５％，两制剂生物等效。Abstract: s Tramadol resinate sustained release suspension was prepared. Compared with normal tramadol capsule, the pharmacokinetics of sustained release suspension was evaluated. The serum concentration of tramadol was deternined by HPLC method. The results r
