摘要 目的:分析加替沙星胶囊的人体药代动力学,为临床用药提供指导。方法:52例下呼吸道感染患者随机自身前后交叉给药,分别单剂口服2种加替沙星片,以HPLC测定血药浓度,应用DAS软件计算两者的药代动力学,并且观察治疗疗效。结果:两者的血药浓度经时变化符合一级消除动力学特征,主要药代动力学参数,滞后时间:(1.23±0.42)d和(1.12±0.36)d;半衰期:(10.26±1.31)d和(9.16±1.28)d;峰时间:(1.59±0.42)d和(1.23±0.36)d;峰浓度:(4.02±0.59)μg/ml和(3.96±0.49)μg/ml;两组治疗有效率均较高,但差异无统计学意义。结论:加替沙星胶囊口服吸收迅速,血药浓度高,组织分布广,消除半衰期长,尿药浓度高,治疗下呼吸道感染有效。
