Formulation parameters and release mechanism of theophylline loaded ethyl cellulose microspheres

Formulation parameters and release mechanism of theophylline loaded ethyl cellulose microspheres

Altering the combined hydrophilic-lipophilic balance (CHLB), by varying the ratio of dual surfactants, on formulation parameters and in vitro drug release of ethyl cellulose microspheres was examined. Theophylline, a xanthine bronchodilator was used to model controlled release owing to its narrow th...
