A mechanistic reaction-diffusion model is proposed for the simulation of drug delivery from PLGA microspheres. The model considers the effects of autocatalytic hydrolysis kinetics and the evolution of the pore network on microsphere-size-dependent drug release. Spatial and temporal variations in the intraparticle pH and the void fraction are reported.
