摘要
21名男性健康受试者三交叉口服托烷司琼受试制剂(胶囊A、片剂B)和参比制剂(胶囊C),进行药物动力学及生物等效性研究。采用HPLC/MS/MS测定血浆中托烷司琼浓度。A、B和C三者的Cmax分别为(44.6±17.7)、(43.9±14.9)和(39.1±13.6)ng/ml,AUC0→48h分别为(673.9±511.3)、(668.6±479.8)和(597.1±462.3)ng·h·ml-1。A、B的相对生物利用度分别为(114.1±20.9)%、(114.8±9.0)%,三者具有生物等效性。
The pharmacokinetics and bioequivalence of test preparations (capsule A, tablet B) and reference preparation (capsule C) of tropisetron were investigated in 21 healthy male volunteers, according to a three-way cross-over design. The concentrations of tropisetron in plasma were determined by HPLC/MS/MS method. The pharrnacokinetics parameters of A, B and C were Cmax (44.6 ± 17.7), (43.9±14.9) and (39.1 ± 13.6) ng/ml, A UC0→48h (673.9 ±511.3), (668.6±479.8) and (597.1 ± 462.3) ng·h·ml^-1,respectively, The relative bioavailability of A and B were (114.1 ± 20.9) % and (114.8 ± 9.0) %, respectively, Three preparations were bioequivalent.
