Abstract

AIMS

To compare raloxifene pharmacokinetics between renally impaired and healthy subjects.

METHODS

Raloxifene 120 mg was administered to 10 males with renal impairment (creatinine 2-4 mg dl(-1)) and to 10 healthy males. Data were analysed by two noncompartmental and one compartmental nonlinear regression methods.

RESULTS

The medians (95% confidence interval) of the area under the curves (AUC) were 35.1 (25.8, 74) and 20.5 (16.8, 28.0) h ng ml(-1) per mg kg(-1), P < 0.01, and of the clearances (CL/F) were 28.5 (13.5, 38.8) and 48.8 (35.8, 59.4) l h(-1) kg(-1), P < 0.01, in renally impaired and healthy subjects, respectively. 95% Confidence intervals on the differences for AUC and CL/F were 6.5-44.1 and -35.1 to -7.9, respectively.

CONCLUSION

Exposure to raloxifene was twice as high in males with renal impairment compared with healthy subjects.

摘要

目的

比较肾功能受损受试者与健康受试者之间雷洛昔芬的药代动力学。

方法

对10名肾功能受损男性(肌酐2 - 4mg dl⁻¹)和10名健康男性给予120mg雷洛昔芬。采用两种非房室和一种房室非线性回归方法分析数据。

结果

曲线下面积(AUC)的中位数(95%置信区间)在肾功能受损受试者和健康受试者中分别为35.1(25.8,74)和20.5(16.8,28.0)h ng ml⁻¹ per mg kg⁻¹,P < 0.01;清除率(CL/F)的中位数(95%置信区间)分别为28.5(13.5,38.8)和48.8(35.8,59.4)l h⁻¹ kg⁻¹,P < 0.01。AUC和CL/F差异的95%置信区间分别为6.5 - 44.1和 - 35.1至 - 7.9。

结论

与健康受试者相比,肾功能受损男性对雷洛昔芬的暴露量高两倍。
