摘　　要：以羟丙甲纤维素和丙烯酸树脂为骨架材料 ,5 %乙基纤维素乙醇溶液作为粘合剂 ,采用湿法制粒压片 ,制备盐酸丁咯地尔缓释片 ,进行体外释放度试验 ,并与进口缓释片进行比较。结果表明 :研制缓释片的缓释效果良好 ,药物的释放符合一级动力学规律。With hydroxypropylmethylcellulose and Eudragit RS PO as carriers, and 5% ethanolic ethylcellulose solution as adhesive, buflomedil hydrochloride sustained release tablets were prepared by wetting granulation method. The release rates of the tablets were determined and compared with imported sustained release tablets. The results indicated that the sustained release tablets had an expected sustained release quality, and the drug release pattern was in accorded with the first order kinetics.
