Diazepam was microencapsulated with ethyl cellulose (EC), gelatin and calcium alginate by complex emulsion methods and the microcapsules were studied. Controlled drug release which depended on per cent coat material in the microcapsules and good linear relationships between per cent coat material and T50 values were observed with EC and gelatin. No such controlled release was observed with calcium alginate.
