An Overview of Polymers Used in Innovative Drug Delivery Systems

Abstract

Polymers are used to make novel drug delivery methods. Pharmaceuticals are protected from physiological conditions by polymers, and their stability is increased by extending their release periods. Diffusion, swelling, and breakdown allow the drug to escape the polymer. The use of several polymers in novel drug delivery systems is being investigated. These include polymeric hydrogel, microencapsulation, adhesive biomaterial, nanoparticle, polymeric implant, polymeric micelles, liposome, ethosomes, and polymer in therapeutic gene therapy. The concept of drug distribution is intimately linked to the administration technique and dosage form. The goal of the innovative drug delivery system is to create the ideal medication with selective targeting to the site of action and regulated delivery. Innovative medication delivery methods use polymer-based tools to alter New medications contain polyethylene oxide, sometimes known as Polyox, a multipurpose polymerIt is the release of a medicine from a controlled release mechanism. Predefined drug delivery rates can be achieved by using natural polymers. Since biodegradable polymers are known to be biocompatible and biodegradable, they have been employed extensively in biomedical applications. Long-term service is expected from polymers, which are typically utilised as implants in the biomedical field. These advancements help to reduce adverse effects and other issues for patients while also increasing the effectiveness of medical care. Polymers' primary functions include shielding medications from physiological environments and extending their release to increase their stability. Diffusion, breakdown, and swelling allow the medication to be released from the polymer. Furthermore, this review outlines the properties and actions of mucoadhesive and plant-derived polymers that are being employed in drug delivery.
