摘要:
A rapid and specific liquid chromatographic-tandem mass spectrometric method is described for simultaneous analysis of valsartan (VAL) and hydrochlorothiazide (HCTZ) in human plasma. VAL and HCTZ were chromatographed on a C-8 column with 75:15:10 (v/v) acetonitrile-methanol-0.001% aqueous ammonia as mobile phase. VAL and HCTZ were eluted at 0.69 min and 1.22 min, respectively, and, after electrospray ionization (ESI), detected in selected-reaction-monitoring mode. The precursor to product-ion transitions m/z 434.32 -> 179.22 and m/z 295.85 -> 204.86 were used to quantify VAL and HCTZ, respectively. Recovery by solid-phase extraction was > 90% for both analytes and the internal standard. The method was suitable for application to a pharmacokinetic study after oral administration of tablet containing 160 mg VAL and 25 mg HCTZ to 18 healthy volunteers.
