英文摘要

A HPLC method with on-line solid phase extraction (SPE) and DAD detection was developed for the simultaneous determination of nitrendipine and hydrochlorothiazide in spontaneously hypertensive rat (SHR) plasma. Plasma samples (100 mu L) were injected directly onto a CAPCELL MF C(8) SPE column. High-abundance proteins and most matrixes in plasma were removed by on-line SPE technology, while nitrendipine and hydrochlorothiazide trapped on the SPE column were effectively separated on a C(18) analytical column. The column temperature was maintained at 20 degrees C. The optimal detection wavelength was 237 nm for NTDP and 271 nm for HCTZ. The total analytical run time was 34 min. The proposed method was linear over the range 5-500 ngmL(-1) for nitrendipine and 10-1000 ng mL(-1) for hydrochlorothiazide. The lower limit of detection (LLOD) was 0.5 and 0.6 ng mL(-1) for nitrendipine and hydrochlorothiazide, respectively. The sensitivity and precision of the method were within acceptable limits during validation period. The method was successfully used to investigate the pharmacokinetic characteristics of nitrendipine and hydrochlorothiazide in spontaneously hypertensive rats. (C) 2011 Elsevier B.V.
