Biodegradable ethyl cellulose (EC) based microcapsules for controlled delivery of Argy Wormwood solution (AWS) was prepared in this study by emulsion-solvent evaporation method using ethyl acetate as solvent. Effects of emulsifier, AWS concentration, EC concentration and ratios of core to shell on the size of the microcapsules, encapsulation efficiency (EE) and drug content were also examined in this study. The increase in the AWS or EC concentrations resulted in enlargement of the microcapsules'. The drug loading increased from 23% to 48% as the AWP concentration was changed from 2 wt% to 10 ...
