Stimuli‐accelerated polymeric drug delivery systems

The controlled delivery of active pharmaceutical ingredients to the site disease represents a major challenge in drug therapy. Particularly when drugs have be transported across biological barriers, suitable systems are importance. In recent years responsive been developed which enable release depending on internal or external stimuli such as changes pH, redox environment light and temperature. some studies with reactivity against two different were established either enhance response by synergies broaden window possible trigger events. present review numerous exciting developments pH-, light- redox-cleavable polymers for preparation smart described. discusses that can used polymer-based systems. It puts focus described stimuli-sensitive systems, their techniques well stimuli-responsive degradation. © 2022 Authors.
