This study was conducted in order to compare the bioavailability of two modified release tablets containing 35 mg of trimetazidine. Twenty-four subjects were enrolled in a single center, randomized, single dose, open label, two-way crossover study with a one-week washout period. Plasma samples were collected up 48 hours following drug administration and trimetazidine was determined by liquid chromatography-tandem mass spectrometry (LC- MS/MS) method with turboionspray mode. Pharmacokinetic parameters used for bioequivalence assessment were AUC 0-t , AUC 0- ∞ and C max . The 90% confidence intervals obtained by analysis of variance for AUC 0-t , AUC 0- ∞ and C max were 94.89-105.15%, 94.85-105.23%, 93.31-107.36%, respectively. These results were all within the range of 80.00-125.00%. Bioequivalence between formulations was concluded both in terms of rate and extent of absorption.
