T he bioavailability of two 500 mg Azithromycin tablet formulations was compared; using generic tablets (Azivol?) as test formulation and the originator product as reference formulation. Twenty-four subjects were included in this single-dose, open label, randomized two way crossover design following an overnight fasting. Two weeks wash out period was applied. Blood samples were drawn up to 120 h following drug administration. Plasma concentration of azithromycin was determined by liquid- chromatography-tandem mass spectrometry method with TurboIonSpray mode. Pharmacokinetic parameters AUC0-t, AUC0- ∞, Cmax and t1/2 were determined and used for bioequivalence evaluation after log-transformation, whereas tmax ratio were evaluated non-parametrically. The estimated point and 90% confidence intervals (CI) for AUC0-t, AUC0-∞ and Cmax were 94.63% (86.27-103.81%), 95.35% (87.15-104.31%), 94.16% (80.31-110.41%), respectively. These result indicated that the two formulations of azithromycin were bioequivalent; therefore they may be prescribed interchangeably
