Abstract

The effect of the concentration of a cross-linking agent (gelatin hardener) on gelatin microspheres was evaluated. A concentration increase of the gelatin hardener (formaldehyde) produced a decrease of drug loading, swelling degree and drug release rate. The cross-linking agent concentration affected also the kinetics of water absorption and drug release. This paper suggests a decreasing significance of the diffusion-type mechanism of drug release as the concentration of the cross-linking agent increased.
