Nonlinearities in Drug Release Process from Polymeric Microparticles: Long‐Time‐Scale Behaviour

This is the authors' abstract. We don't add key points for this paper.

A theoretical model of the drug release process from polymeric microparticles (a particular type of polymer matrix), through dispersive fractal approximation of motion, is built. As a result, the drug release process takes place through cnoidal oscillations modes of a normalized concentration field. This indicates that, in the case of long‐time‐scale evolutions, the drug particles assemble in a lattice of nonlinear oscillators occur macroscopically, through variations of drug concentration. The model is validated by experimental results.
