Ethyl cellulose, hydroxy propyl methyl cellulose, Methaceylic acid were investigated as a sustained release matrix. Theophylline is used as a model drug for evaluating sustained release drug delivery system. Ethyl cellulose, hydroxyl propyl methyl cellulose, methaceylic acid were used in different concentration i.e. 2%, 3%, 5%, 7.5%, 10% w/w, along...
