Abstract The purpose of this study is to characterize controlled release matrix tablets of captopril and to find out the physicochemical properties that have an effect on the mucoadhesion process. The hydrophilic matrix tablets contain captopril, microcrystalline cellulose, barium sulfate, ascorbic acid, ethylcellulose N100, hydroxypropylmethylcellulose K15M, talc, magnesium stearate and colloidal silicon dioxide. The physicochemical properties of the formulations have been characterized using...
