摘 要:以 HPMC为缓释材料 ,采用湿法制粒制备缓释片 ,用体外释放度试验研究了缓释片的释药机理及影响因素。结果表明 ,缓释片的释放符合 Higuchi方程 ,HPMC的粘度、用量、丙烯酸树脂 号的用量。Cefaclor sustained-release tablets were prepared with wet methods, the mechanism and the influencing factors on drug release were studied through the releasing tests. The results showed that the drug releasing rate from the tablets followed Higuchi equation and the effects of HPMC viscosity, content, Eudragit L100 content, pressure on cefaclor release were significant.
