Abstract

Losartan potassium is a non-peptide molecule and selective competitive angiotensin II type 1 receptor (AT1) receptor antagonist which is mainly used as a first line treatment for the patients suffering from hypertension. In the present research work Losartan potassium loaded microcapsules were fabricated by using modified double emulsion solvent evaporation method and further more they were incorporated into mucoadhesive gastro retentive tablets. The release kinetic of the prepared tablets was evaluated by using PCP Disso V3® software and it selected ‘zero order’ model as the best fitting model, supporting the sustained release property of the final oral dosage forms which was the primary objective of the present study. Final formulations were subjected to comparison with three different marketed conventional dosage forms on the basis of dissolution property and it showed better release pattern than the rest.
