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.
Keywords: Biodegradable polymers, Controlled drug delivery, Drug release method, Polymers.
