摘  要:目的研究复方缬沙坦(抗高血压药)在中国健康受试者体内的药代动力学特征,并评价其生物等效性。方法采用双周期、两制剂交叉试验设计,20名健康男性受试者随机交叉、先后单次交叉口服国产复方缬沙坦(每片含缬沙坦80 mg/氢氯噻嗪12.5 mg)(被试制剂)和进口复方缬沙坦(每片含缬沙坦80 mg/氢氯噻嗪12.5 mg)(参比制剂)各1片,用液相色谱-串联质谱法(LC/MS/MS)同时测定血浆中的缬沙坦和氢氯噻嗪浓度。结果被试制剂和参比制剂的药代动力学参数,缬沙坦:Cmax分别为(2.39±1.28),(2.61±1.23)μg.mL-1;tmax分别为(3.1±1.4),(3.4±0.7)h;t1/2分别为(7.5±1.8),(7.4±1.6)h;AUC0-t分别为(16.95±8.85),(18.14±9.06)μg·mL-1·h。氢氯噻嗪:Cmax分别为(0.40±0.18),(0.42±0.15)μg·mL-1;Tmax分别为(2.6±1.6),(2.2±1.0)h;t1/2分别为(9.6±1.4),(9.8±1.8)h;AUC0-t分别为(2.85±1.05),(2.80±0.89)μg·mL-1·h。国产复方缬沙坦中缬沙坦和氢氯噻嗪的相对生物利用度分别为(93.9±20.3)%和(102.1±22.2)%。结论 2种制剂具有生物等效性。Objective To study the bioequivalence of compound valsartan tablets in Chinese healthy volunteers after single oral administration.Methods Twenty male healthy volunteers were enrolled in a randomized two-way crossover study.The plasma concentrations of valsatarn and hydrochlorothiazide were determined by the sensitive LC/MS/MS method.Results To valsartan,the main pharmacokinetic parameters of test and reference formulations were as follows: Cmax were(2.39±1.28),(2.61±1.23) μg·mL-1;tmax were(3.1±1.4),(3.4±0.7) h;t1/2 were(7.5±1.8),(7.4±1.6) h;AUC0-t were(16.95±8.85),(18.14±9.06) μg·mL-1·h.To hydrochlorothiazide,the main pharmacokinetic parameters were as follows: Cmax were(0.40 ±0.18),(0.42±0.15) μg·mL-1;Tmax were(2.6±1.6),(2.2±1.07) h;t1/2 were(9.6±1.4),(9.8±1.8) h;AUC0-t were(2.85±1.05),(2.80±0.89) μg·mL-1·h.The relative bioavailability of valsatarn and hydrochlorothiazide were(93.9±20.3)% and(102.1±22.2)%,respectively.Conclusion The result demonstrated that two formulations were bioequivalent by analysis of variance,two one-side t test and 90% confidence interva1.
