摘　　要：应用多元线性回归方法考察卡波姆 934、丙烯酸树脂 II、硬脂酸对盐酸地尔硫释放的影响 ,通过调整各辅料的用量比例 ,制备在不同溶出介质中具有相同释药曲线且能维持 2 4 h释药的地尔硫粘附胶囊。根据各个释放模型拟合的 AIC值、计算值与实测值的相对误差来研究其释药规律。根据 Peppas方程特征参数判断其释药机制主要为药物扩散。A multiple linear regression equation was applied to investigate effects of Carbomer 934, Eudragit II and stearic acid on release rate of diltiazem hydrochloride. The 24 h sustained release capsules of diltiazem hydrochloride had the same release rate curve in three different mediums by adjusting the proportion of excipients. According to the value of AIC and relative errors between calculated and measured values, the release rule was determined. The values of characteristic parameter of Peppas equation indicated that release mechanism of diltiazem was diffusion release.
