Trial overview

Official title: Open, two periods, two treatments, two sequences, cross-over, randomized study with single dosage of two oral preparations containing 1 g of Cephalexin (GlaxoSmithKline México, S.A. de C.V. vs. Keflex® 1g, Eli Lilly y Compañía de México, S.A. de C.V.) in fasting healthy volunteers.
Trial description: The objective of this study was to confirm if two formulations of cephalexin tablets are bioequivalent.
Test product was Ceporex® (1 g Cephalexin; GlaxoSmithKline) and reference product Keflex® (1 g Cephalexin; Eli Lilly). 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, both genders, adults between 18-40 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.
