中文摘要
目的建立测定人血浆中氯雷他定浓度的方法,研究氯雷他定的片剂及胶囊在人体内的相对生物利用度。方法23例健康男性志愿者随机三交叉自身对照,分别单剂po受试制剂氯雷他定片剂和胶囊及参比片剂各40 mg后,HPLC测定血浆中氯雷他定的浓度,运用3p97程序计算有关药动学参数。结果氯雷他定的体内过程符合二室模型,受试片剂和胶囊及参比片剂的AUC0-12分别为147.00±102.75、135.41±94.24、139.76±94.76 ng.ml-1.h,Cmax分别为68.20±37.47、57.52±39.17、66.49±41.41 ng.ml-1,Tmax分别为0.78±0.22、0.98±0.24、0.98±0.37 h。受试片剂与参比片剂的相对生物利用度(F)为110.0%±40.0%,胶囊为98%±23%。结论结果显示,受试氯雷他定片剂及胶囊与参比制剂均生物等效。
