Bioequivalence Study for Terbinafine 250 mg

The objective of this study was to confirm if two formulations of terbinafine (tablets) are bioequivalent.

Test product was Xilatril® 250 mg (Laboratorios Dermatológicos Darier) and reference product Lamisil® 250 mg (Novartis). One tablet was the single dosage.

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 30 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.
