          Abstract

          Dentro del proceso global de la liberación de un fármaco, la disolución constituye el paso más importante pues se encuentra íntimamente relacionada con los procesos de absorción, determinantes en la biodisponibilidad de un medicamento administrado por vía oral. En el presente trabajo se realizaron los perfiles de disolución de 3 lotes de Zantac® (GlaxoWellcome), medicamento líder del principio activo ranitidina (DCI) y de 3 lotes de ranitidina 150 mg de producción nacional. Para el estudio de disolución se utilizó el método descrito en la USP 23. Los datos de porcentaje de principio activo liberado contra tiempo fueron sometidos a un estudio de ajuste a 4 modelos comunes a perfiles de disolución mediante el programa CurveExpert. Todos los lotes estudiados cumplen con los criterios de la Food and Drug Administration (FDA) para los estudios de bioequivalencia in vitro.

          Translated abstract

          Dissolution is the most important step in the global release process of a drug , since it is closely related to the absorption processes, which are determinant in the bioavailability of a drug administered by oral route. The dissolution profiles of 3 batches of Zantac® (Glaxo Wellcome), a leading drug of the ranitidine active principle (DCI), and of 3 batches of ranitidine 150 mg of national production were performed. The method described in the USP 23 was used for the dissolution test. The percentage data of the active principle released against time were subjected to a study of adjustment of 4 models to common disssolution profiles by the CurveExpert program. All the studied batches fulfilled the criteria of the Food and Drug Administration (FDA) for the in vitro bioequivalence studies.
