摘要:

本文建立了简单、快速的HPLC方法测定利巴韦林在人血浆中的含量, 并研究了健康受试者体内利巴韦林片剂的药代动力学。HPLC方法选择C18色谱柱(250 mm×4.6 mm, 5 μm), 超纯水为流动相, 柱温为25 °C, 检测波长为207 nm。在50.4-2016.0 ng/mL范围内线性关系良好(r = 0.9998), 最低检测浓度为15 ng/mL。低、中、高三个浓度的相对回收率大于90%, 日内精密度小于10%, 日间精密度小于15%。用药代动力学软件WinNonlin进行房室模型分析的结果显示: 二室模型能更好地模拟利巴韦林在体内的过程。计算得到的AUC0-t 、CL/F和Cmax分别是10807.8 h∙ng/mL、 64879.5 mL和 525.1 ng/mL。这些结果为药剂工作者开发利用利巴韦林剂型提供了参考。

Abstract:

The clinical pharmacokinetics of ribavirin after a single oral dose of 600 mg ribavirin tablets in healthy Chinese volunteers was studied. A rapid and simple high performance liquid chromatography (HPLC) method was developed to determine the ribavirin concentration in human plasma. C18 column was used for separation with a column temperature of 25 °C, the mobile phase was ultrapure water adjusted to pH 3 with acetic acid at the flow rate of 1 mL/min, and the detection wavelength was set at 207 nm. The linear range of the standard curves was 50.4-2016.0 ng/mL and the lower limit of quantification (LLOQ) was 50.4 ng/mL. The relative recoveries of ribavirin were more than 90% in plasma. The RSD of the intra-day precision was less than 10% and that of inter-day was less than 15%. The pharmacokinetic parameters of ribavirin were calculated by WinNonlin. Results indicated that the two-compartment model was a better model for describing the pharmacokinetics profile of ribavirin than one-compartment model. The AUC0-t was 10807.8 h∙ng/mL, the CL/F was 64879.5 mL, and the Cmax was 525.1 ng/mL. These results provided the experimental data for the development of ribavirin dosage form.
