摘要

建立了同时测定人血浆中磺胺甲恶唑(SMZ)和甲氧苄啶(TMP)含量的高效液相色谱法。血浆中TMP和SMZ的检出限分别为5和10ng mL−1。两种化合物的平均回收率约为96%。日间和日间的变异系数小于8%。该方法简便、灵敏,适用于磺胺甲恶唑和甲氧苄啶的药动学研究。

Simultaneous High‐Performance Liquid Chromatographic Determination of Sulphamethoxazole and Trimethoprim in the Plasma of Man
An HPLC method has been developed for simultaneous analysis of sulphamethoxazole (SMZ) and trimethoprim (TMP) in plasma from man. The detection limits for TMP and SMZ in plasma were 5 and 10ng mL−1, respectively. The average recovery for both compounds was 96% (approx.). The inter- and intra-day coefficients of variation of the assay were found to be less than 8%. The method is simple, sensitive and suitable for pharmacokinetic studies of sulphamethoxazole and trimethoprim.
