History: No changes posted

The objective of this study was to confirm if two formulations of escitalopram tablets are bioequivalent.

Test product was escitalopram (10 mg; GlaxoSmithKline) and reference product Lexapro® (10 mg escitalopram; Lundbeck). The single dosage was one tablet.

The study was prospective, open-label, randomized, crossover, single dose, with 02 treatments, 02 sequences and 02 periods, under fasting conditions.

The population was composed of 26 healthy volunteers, male adults between 18-50 years.

The comparative bioavailability of the two formulations was evaluated based in statistical comparisons of relevant pharmacokinetic parameters, obtained from data of drug concentrations in blood.
