摘要 目的:研究2种舒他西林片剂的药动学及相对生物利用度,并评价其生物等效性。方法:采用随机交叉试验设计,18名受试者单剂量口服750 mg受试制剂和参比制剂,以高效液相色谱法(HPLC)测定血药浓度。结果:受试制剂和参比制剂中的氨苄西林主要药动学参数t_(max),c_(max),t_(1/2)和AUC_(0-8)分别为:(1.1±s0.3)和(1.2±0.4)h;(10±5)和(11±6)mg·L^(-1);(1.8±0.5)和(1.6±0.4)h;(22±15)和(22±15)mg·h·L^(-1)。受试制剂中氨苄西林对参比制剂氨苄西林的相对生物利用度F为(100±10)%。受试制剂和参比制剂中的舒巴坦主要药动学参数t_(max),c_(max),t_(1/2)和AUC_(0-8)分别为:(1.2±0.3)和(1.3±0.4)h;(5.5±1.2)和(5.6±1.1)mg·L^(-1);(1.5±0.3)和(1.46±0.28)h;(10.6±2.1)和(10.2±1.6)mg·h·L^(-1)。受试制剂中舒巴坦对参比制剂舒巴坦的相对生物利用度F为(102±11)%。结论:2种舒他西林制剂具有生物等效性。 AIM: To study the phamacokinetics and correlative bioavailability and evaluate the bioequivalence of two kinds of suhamicillin tablets. METHODS: A random crossover trial was designed. Plasma concentrations were determined by HPLC method following a single oral dose 750 mg of two different brands suhamicillin tablets. RESULTS: The ampicillin pharmacokinetic parameters of the test tablets and the reference tablets in plasma were as following: tmax were(1.1 ± s 0.3) vs (1.2 ±0.4) h; cmax were(10 ± 5) vs (11 ± 6) mg·L^-1; tmax were (1.8 ± 0.5) vs (1.6 ± 0.4) h; AUC0-8 were (22 ± 15) vs (22 ± 15) mg·h·L^-1, respectively. The ampicillin bioavailability of the test tablets was(100 ± 10) % in correlative with the reference tablets. The sulbactam pharmacokinetic parameters of the test tablets and the reference tablets in plasma were as following: tmax were (1.2 ± 0.3) vs (1.3 ± 0.4) h; cmax were (5.5 ± 1.2) vs (5.6 ± 1.1) mg·L^-1; t1/2 were (1.5 ± 0.3) vs (1.46 ± 0.28) h; A UC0-8 were (10.6 ± 2.1 ) vs (10.2 ± 1.6) mg· h· L^-1, respectively. The sulbactam bioavailability of the test tablets was (102 ± 11) % in correlative with the reference tablets. CONCLUSION: The two kinds of suhamicillin tablets are bioequivalent.
