摘要 目的研究氯沙坦对家兔环孢素A(CsA)药代动力学的影响。方法采用荧光偏振免疫法(FPIA法)测定6只家兔合用氯沙坦前后CsA的血药浓度,并对2组(单用CsA组和合用氯沙坦组)药代动力学参数进行分析。结果合用氯沙坦组的CsA峰浓度(Cmax)、曲线下面积(AUC0→24)均显著升高(P<0.01),血浆清除率(CL)及表观分布容积(V)均显著降低(P<0.05或P<0.01),其余药动学参数无显著性变化(P>0.05)。结论合用氯沙坦可升高CsA的血药浓度,临床上其与CsA合用需监测CsA的血药浓度,保证治疗的安全有效。 Objective To study the influnce of losartan on pharrnacokinetics of cyclosporin A (CsA) in rabbit. Methods By fluorescence polarization immunoassay( FPIA method) , determined blood concentration of CsA of six rabbits before and after combined losartan, and analysed pharmacokinetic parameters of two groups ( single combination with CsA group and losartan group). Resnlts The peak concentration ( Cmax ) of CsA of losartan group significantly increased, area under the curve ( AUCν0-24 ) increased significantly( P 〈 0.01 ), plasma clearance(CL) and decreased and apparent volume of distribution ( V ) .significantly decreased (P 〈 O. 05 or P 〈 0.01 ), the remaining pharmacokinetic parameters had no significant change( P 〉 0.05 ). Conclusion Combineing losartan can increase CsA blood concentration,it combineing CsA must monitor CsA concen- tration in blood, and ensure safe and effective treatment.
