Brief summary: The objective of this study was to confirm if two formulations of nimesulide tablets are bioequivalent.

Test product was Eskaflam® (Nimesulide 100 mg tablets; GlaxoSmithKline) and reference product Mesulid® (Nimesulide 100 mg tablets; Syntex for Productos Roche). 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 28 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.
