Abstract
This review explores the potential of polymeric nanoparticles (PNPs) as targeted drug delivery systems for arthritic treatment, overcoming the limitations of the present therapy. A thorough literature search was conducted on the databases PubMed, Scopus, and Web of Science to find published articles on the use of polymeric nanoparticles in the treatment of arthritis. This includes synthesis methods, mechanisms in drug delivery, and applications of PNPs. Polymeric nanoparticles showed excellent promise in the management of arthritis through enhanced stability of drugs, controlled and sustained drug release, and reduced systemic side effects. Some of the highlighted biocompatible and targeting capabilities of natural and synthetic polymers include chitosan, hyaluronic acid, and PLGA. Bioactive compounds such as curcumin and resveratrol delivered by PNPs enhanced therapeutic efficacy in preclinical arthritis models. Despite their promise, challenges such as rapid clearance and manufacturing scalability remain critical barriers. Polymeric nanoparticles offer a transformative approach to arthritis management by enabling targeted, sustained, and safe drug delivery. Translation into clinical applications would thus require developments in nanoparticle design, personalized medicine, and scalable production techniques.
