Trial overview

Official title: Open, two periods, two treatments, two sequences, cross-over, randomized study with single dosage of two oral preparation of Cephalexin 250 mg/5mL (Ceporex®, GlaxoSmithKline México, S.A. de C.V. vs. Keflex® , 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 suspension are bioequivalent.
Test product was Ceporex® (250 mg Cephalexin / 5 ml; GlaxoSmithKline) and reference product Keflex® (125 mg Cephalexin / 5 ml; Eli Lilly). The single dosage was 10 ml of suspension for Ceporex and 20 ml of suspension for Keflex® .
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 28 healthy volunteers, both genders, 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.
