摘　　要：研制阿昔洛韦缓释片 ,并对其体外释放特点和初步的体内过程进行了研究。分别采用紫外分光光度法和高效液相色谱荧光检测法对阿昔洛韦进行体外释放度和体内血药浓度测定。采用 4例志愿者单剂量口服缓释片和市售片 ,测定血药浓度并计算药动学参数。该缓释片在体外和体内均具有缓释作用 ,与参比制剂比较 ,服用缓释片组血药浓度较为平稳和持久 ,AUC增大 ,峰浓度降低 ,达峰时间延长。Acyclovir(ACV) sustained release tablets(SRT) were prepared. The releasing characteristics in vitro and the pharmacokinetics in vivo were studied primitively. UV method was established for assaying release of SRT in vitro . The HPLC fluorescence method was established to monitor plasma level in vivo . Four healthy volunteers were chosen to perform in vivo study, each two with single dose of ACV SRT and commercial tablets. Pharmacokinetics of the SRT was characterized preliminarily. It was concluded from the study of four healthy volunteers that T max and AUC increased, C max decreased, and the curve of plasma concentration versus time became more flat and extended longer compared with reference tablets.
