The aim of this study was to prepare, using taste masked granules, rapidly disintegrating tablets of chlorpheniramine maleate, a bitter drug. The taste masked granules were prepared using aminoalkyl methacrylate copolymers (Eudragit E-100) by the extrusion method. In vitro release profile obtained at pH 6.8 indicate that perceivable amount of drug will not be released in saliva while high percent release (more than 80% in 30 min) would be obtained at acidic pH 1.2 of the stomach. These taste masked granules were directly compressed into tablets using sodium starch glycolate as a super-disintegrant. The prepared tablets containing the taste masked granules having sufficient strength of 3.5 kg/cm were evaluated for taste by both spectrophotometric method and through panel testing. Panel testing data collected from 20 healthy volunteers indicate successful formulation of oral fast disintegrating tablets which had good taste and disintegrated in the oral cavity within 30s.
