Volume 31 Issue 2 April 2008 pp 159-167 Polymers
Interpenetrating polymer network (IPN) beads consisting of chitosan–glutamic acid were prepared for
in vitro study of controlled release of chlorpheniramine maleate (CPM). A viscous solution of chitosan–glutamic acid was prepared in 2% acetic acid solution, extruded as droplets through a syringe to alkali–methanol solution and the precipitated beads were crosslinked using glutaraldehyde solution. Swelling and drug release studies were carried out. Transport of release medium through the semi-IPN depended upon its pH and extent of crosslinking. The structural and morphological studies of beads were carried out by using a scanning electron microscope (SEM). The larger surface area of beads as well as their ease of handling makes them ideal agents of controlled release.
