**4. Conclusion and future trends**

The topic of stimuli-sensitive polymeric materials is quickly evolving, with evidence of its pharmacokinetic and therapeutic usefulness in the delivery of drugs. Stimuli-sensitive polymeric materials, which constitute an adaptive delivery strategy, have been proven to effectively respond in the required manner to the associated stimuli and are interesting prospects as a specific drug delivery option. Despite the fact that most of these polymeric' multifunctionality qualities enable for a variety of health uses, stimuli sensitive polymeric substances have limited therapeutic potential due to cytocompatibility and toxicity concerns. The enormous progress and different benefits and prospects of stimuli-sensitive polymeric materials have been highlighted in this chapter. Despite the various options that are already available, additional research into healthier and much more biocompatible delivery mechanisms has still been needed.
