Bioequivalence Study of Montelukast 10 mg Tablets
Open, Two Periods, Two Treatments, Two Sequences, Cross-over, Randomized Study With Single Dosage of Two Oral Preparations Containing Montelukast 10 mg (Product of GlaxoSmithKline México, S.A. de C.V. vs. Singulair, Merck Sharp & Dohme de México, S.A. de C.V.)in Fasting Healthy Volunteers
The objective of this study was to confirm if two formulations of montelukast tablets are bioequivalent.
Test product was Montelukast (10 mg tablets; GlaxoSmithKline) and reference product Singulair (10 mg tablets; Merck Sharp & Dohme). 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 32 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.
