摘要 目的:研究重庆科瑞制药有限公司生产的青霉素V钾片(以下称试验药)的人体生物等效性。方法:20名健康男性志愿者随机分为A、B两组,每组10人,采用随机交叉试验设计,单剂量口服青霉素V钾片试验药或对照药750mg,高效液相色谱法测定血清中药物浓度,3P97计算机软件计算药动学参数。结果:试验药扣对照药的cmax分别为(10.23±4.81)μg/mL和(10.05±4.49)μg/mL;Tmax分别为(0.44±0.16)h和(0.54±0.13)h;t1/2(β)分别为(0.59±0.4)h和(0.51±0.28)h;AUC(0-∞)分别为(9.15±3.34)μg/(h·mL)和(9.71±4.04)μg(h·mL);AUC(0-T)分别为(8.97±3.43)μg(h·mL)和(9.54±3.96)μg/(h·mL)。试验药的人体相对生物利用度为(94.02±16.31)%。结论:青霉素V钾片试验药与市售药比较具有生物等效性。 Objective: To study the bioequivalence of phenoxymethylpenicillin potassium tablets. Methods: A single oral dose of 750 mg phenoxymethylpenicillin potassium tablet was given to 20 healthy male volunteers in an open randomized cross-over test. The plasma levels of phenoxymethylpenicillin potassium were determined by HPLC with ultraviolet detection. Results: The pharmacokinetic parameters of tested and phenoxymethylpenicillin potassium tablets were as follows, Cmax was (10.23 ± 4.81 )μg/mL and (10.05 ± 4.49)μg/mL; Tmax was (0.44 ± 0.16)h and (0 .Y4 ±0.13)h; t1/2(β) was (0.59 ± 0.4)h and (0.51 ± 0.28)h; AUC(0-∞) was (9.15 ± 3.34)μg/(h·mL) and (9.71 ± 4.04)μg/(h·mL); AUC(0-T) was (8.97 ± 3.43)μg/(h· mL) and (9.54 ± 3.96)μg/(h·mL). The relative bioavailability of phenoxymethylpenicillin potassium tablet was (94.02 ± 16.31)%. Conclusions: This study shows that the two kinds of preparations are bioequivalent.
