Polymers: Backbone of Controlled Drug Delivery

The concept of a drug-delivery system (DDS) is not entirely new. Recent years have undoubtedly seen notable advancements in the identification and management of several illnesses. Medication administration to affected areas is an important part of DDS. A sufficient number of drug carriers are required to deliver an adequate amount of drug to the lesion. Polymers that expand and condense in reaction to pH levels outside of the body are being studied by researchers. The investigation is being carried out at a breakneck pace all over the world. Not only are advances in traditional technologies being made but innovations are also being developed and tested. The purpose of this chapter is to discuss a few of the polymer compounds that are utilized in controlled medication delivery systems. Both newcomers and scientists working in this fascinating field of applied polymer research will find the paper to be a valuable resource.
