Enhancement of Dissolution of Telmisartan by Surface Solid Dispersion Technique

open access: yesJournal of Pharmaceutical Research, 2012
Telmisartan is an Angiotensin Receptor Blocker (ARB) used for the treatment of hypertension. It belongs to BCS class-II i.e. low solubility and high permeability and exhibits variable bioavailability. The objective of the present study was to prepare surface solid dispersions of telmisartan to improve its aqueous solubility and dissolution rate.
