Abstract
Semi-interpenetrating polymer network microspheres of chitosan with glycine have been prepared for encapsulation and controlled release of isoniazid (INH) as a model drug. The method involved the exposure of microspheres to the vapor of cross-linking agent to effect the cross-linking under mild conditions. The swelling behavior, hydrolytic degradation and loading capacity of microspheres for INH have been investigated. The prepared microspheres have shown 96% drug loading capacity, which suggested that these semi-interpenetrating polymer network microspheres are suitable to controlled release of drugs in an oral sustained delivery system.
