摘要
目的:研究头孢克肟胶囊在健康人体内的药动学及生物等效性。方法:以18名健康志愿者为试验对象,采用同体交叉试验方法,分别单剂量口服受试制剂或参比制剂各400mg,采用HPLC法测定血浆中药物浓度。结果:参比制剂和受试制剂的tmax分别为(3.39±0.50)和(3.39±0.50)h,cmax分别为(2.33±0.33)和(2.27±0.25)μg/mL,t1/2分别为(3.92±0.85)和(4.41±0.68)h,AUC0~16分别为(14.61±2.67)和(14.82±2.02)μg·h·mL^-1,AUC0~∞分别为(16.00±3.13)和(16.81±2.62)μg·h·mL^-1。结论:受试制剂与参比制剂生物等效,受试制剂的相对生物利用度为(98.69±13.13)%。
Objective: To study the pharmacokinetics and bioequivalence of cefixime capsules in healthy human. Methods:A single oral dose of 400 mg cefixime was given to 18 healthy volunteers in a randomized,cross-over study. Serum concentrations of cefixime were determined by HPLC method. Results:The main pharmacokinetic parameters of the reference and test capsules were as follows: tmax(3.39±0.50)and(3.39±0.50)h ,cmax (2.33±0.33) and (2.27±0. 25)μg/mL,t1/2 (3.92±0. 85) and (4. 41±0.68) h,AUC0-16 (14. 61 ±2.67) and (14.82±2.02)μg· h · mL^-1 ,AUC0-∞ (16.00±3.13) and (16.81±2. 62) μg · h · mL^- 1. Conclusion:The two formulations were bioequivalent. The relative bioavailability of test capsules is (98.69±13.13)%.
