摘要: 目的:评价坎地沙坦酯片、胶囊与进口参比制剂在健康人体内的药代动力学及其生物等效性。方法:采用三制剂三周期二重3×3 拉丁方设计, 18 名健康男性志愿者交叉单剂量口服受试制剂坎地沙坦酯片、胶囊和参比制剂坎地沙坦酯片各16 mg 后, 采用高效液相色谱—荧光法测定不同时间血浆中主要代谢产物坎地沙坦浓度, 用DAS 药动学程序进行药代动力学参数的计算及生物等效性评价。结果:受试制剂坎地沙坦酯片、胶囊和参比制剂坎地沙坦酯片的主要药代动力学参数:tmax 分别为(4.6±0.9)、(4.6±1.3)和(4.4±0.9)h, t1/2分别为(8.8±1.9)、(8.3±1.9)、(8.5±1.8)h, Cmax 分别为(170±61)、(155±75)和(171±77)ng/mL,AUC0-36分别为(1762±576)、(1684±600)和(1808±662)ng°mL-1°h, AUC0-∞ 分别为(1886± 616)、(1776± 600) 和(1913±694)ng°mL-1°h。两种受试制剂的相对生物利用度分别为97.8%和93.1%。结论:两种受试制剂和参比制剂具有生物等效性。

Abstract: AIM: To investigate the pharmacokinetics and bioequivalence of candesartan cilexetic tablets, capsules and imported tablets in healthy volunteers.METHODS: A single oral dose 16 mg of three formulations was randomly given to 18 healthy volunteers in a three cycle duplex 3×3 latin square crossover design.The concentration of candesartan in plasma, which is a major metabolite of candesartan cilexetic, was determined by HPLC-FLD at different times. The pharmacokinetics parameters were calculated and the bioequivalence of three formulations were evaluated by DAS program.RESULTS: The main pharmacokinetic parameters of candesartan cilexetic tablets, capsules and imported tablets were as follows:tmax were (4.6±0.9), (4.6±1.3)and (4.4±0.9)h, t1/2 were(8.8±1.9), (8.3±1.9), (8.5±1.8)h, Cmax were(170±61), (155±75)and (171±77)ng°mL, AUC0-36 were(1762±576), (1684±600)and (1808±662)ng°mL-1 °h, AUC0-∞ were (1886±616), (1776±600)and (1913±694)ng°mL-1 °h.The relative bioavailability of tested tablets and capsules were 97.75% and 93.11%.CONCLUSION: The two tested formulations are bioequivalent with reference formulation.
