Biodegradable Polymer Use in  Drug Delivery Systems: A Comprehensive Review

Biodegradable polymers have revolutionized the field of drug delivery systems, offering a promising solution to the limitations of traditional drug administration techniques. These polymers can be designed to degrade at specific rates, releasing therapeutics in a controlled and sustained manner, thereby improving bioavailability and reducing side effects. This review provides an overview of biodegradable polymers, including natural polymers like collagen, albumin, and gelatin, as well as synthetic polymers like polyesters, polyorthoesters, and polyphosphoesters. Here discuss the types of biodegradable polymers, their mechanisms, and benefits in drug delivery systems, including controlled release, targeted release, transdermal delivery, gene delivery, and tissue engineering. The review also highlights the future prospects and trends in biodegradable polymers, including the development of new polymers, blends, and nanoparticles.
