A Review on the Role of Polymers in Pharmaceutical Drug Delivery System

Abstract

Abstract : This review article focuses on polymers of therapeutic agents used in pharmaceuticals. These dosage forms include e.g tablets, patches, tapes, films, semi-solids and powders. As such, polymers are the backbone of pharmaceutical drug delivery systems check the release of the drug from the device. Biodegradable polymers draw attention to its use because they can degrade Based on a biodegradable polymer, non-toxic monomers and, most importantly, a constant drug release rate can be achieved. controlled release device. Natural polymers can be used as a tool to achieve predetermined drug release rates and these Physicochemical properties and easy availability create a platform for its use as a polymer in drug delivery systems. Biodegradable polymers have been widely used in biomedical applications due to their known biocompatibility and biodegradability In the biomedical field, polymers are often used as implants and are expected to function for a long time. These improvements improve the effectiveness of treatment and minimize side effects and other types harm to patients. The main function of the polymer is to protect the drug from the physiological environment and prolong the release of the drug improve its stability. The drug is released from the polymer by diffusion, degradation and swelling. In addition to this review presents Properties and behavior of plant-based and mucoadhesive polymers currently used for drug delivery.
