In vitro release of chlorpheniramine maleate (CPM) from formaldehyde rigidized gelatin micropellets was studied. The dissolution profile correlated well with the requirements for drug release from sustained release dosage forms. The resulting formulations significantly prolong the drug release and not more than 41 percent of the embedded drug released within the first 30 minutes of in vitro dissolution study.
