Abstract In this review the current knowledge of protein degradation during preparation, storage and release from poly(lactic-co-glycolic acid) (PLGA) microparticles is described, as well as stabilization approaches. Although we have focussed on PLGA microparticles, the degradation processes and mechanisms described here are valid for many other polymeric release systems. Optimized process conditions as well as stabilizing excipients need to be used to counteract several stress factors that compromise the integrity of protein structure during preparation, storage, and release. The use of various stabilization approaches has rendered some success in increasing protein stability, but, still, full preservation of the native protein structure remains a major challenge in the formulation of protein-loaded PLGA microparticles.
