Sensitive and Rapid Method to Determine Trimetazidine in Human Plasma by Liquid Chromatography/Tandem Mass Spectrometry
Abstract:A simple, sensitive, and rapid liquid chromatographic/tandem mass spectrometric (LC/MS/MS) method, using electrospray ionization, was developed and validated to quantify trimetazidine in human plasma using propranolol hydrochloride as an internal standard (IS). Samples were prepared by solid-phase extraction and analyzed without drying and reconstitution. The analyte and IS were chromatographed on a C18 reversed-phase column under isocratic conditions using 2 mM ammonium acetate (pH 3.5) acetonitrile (40 + 60, v/v) as the mobile phase with a run time of 2.0 min. Quantitation was done on a triple-quadrupole mass analyzer API-3000, equipped with turbo ion spray interface and operating in multiple reaction monitoring mode to detect parent product ion (m/z 267.2 181.4) transition. The method was validated for sensitivity, accuracy and precision, linearity, recovery, matrix effect, and stability. Linearity in plasma was observed over the concentration range of 1.5300 ng/mL. Lower limit of quantification achieved was 1.5 ng/mL with precision <10 using 10 L injection volume. The mean relative recovery of analyte (97.36) and IS (99.93) was consistent and reproducible. Interbatch and intrabatch precision was <8.0 and the accuracy determined was within 8 in terms of relative error.
