remains one of the leading causes of morbidity and mortality. The captopril and
losartan drugs are the first choice for treatment. In order to assess the conformity of
products and determine their biopharmaceutical equivalence, a total of 19 commercial
brands available in drug stores and pharmacies in four major cities of the country
(Bogotá, Cartagena, Cali and Barranquilla) were evaluated. To this end the physical,
chemical and biopharmaceutical characteristics of the tablets, such as weight variation,
hardness, disintegration, dissolution, dissolution profile, the dissolution efficiency
and value of the active substance were evaluated. This latter from optimized
and validated methodologies. Pharmacopeial assays were evaluated as provided in
USP 35 NF 30. The results obtained allowed to establish that all models tested
met the acceptance criteria in the Pharmacopoeia for each principle, and the biopharmaceutical
behavior of brands is very similar for both types of molecule. The
results of this work allows to propose the scientific community the determination
of the biopharmaceutical equivalence as support in making purchasing decisions
in the pharmaceutical service.
