Abstract: BACKGROUND: In recent years, hydrogels have become an important research direction in the treatment of rheumatoid arthritis due to their excellent biocompatibility, controllable drug release performance, and advantages in multiple drug delivery routes.
OBJECTIVE: To systematically review the application of hydrogel-based materials as drug delivery carriers in the treatment of rheumatoid arthritis, and explore the impact of different administration routes on the therapeutic effect. 
METHODS: Using “hydrogel, rheumatoid arthritis, smart hydrogel system, injectable hydrogel, intra-articular injection, transdermal drug delivery” as Chinese and English search terms, we searched PubMed, Web of Science, CNKI, WanFang Data, and VIP. Based on the inclusion criteria, 62 articles were finally included for review.
RESULTS AND CONCLUSION: Hydrogels, leveraging their three-dimensional network structures and tunable physicochemical properties, not only allows drugs to accurately reach the lesion area but also significantly prolongs the retention time of drugs in the joint cavity, making them an ideal carrier in the field of drug delivery. The drug release mechanisms of hydrogels mainly include diffusion, chemical regulation, and swelling-mediated release; in addition, stimulus-responsive hydrogels can dynamically regulate drug release behavior based on environmental conditions (such as pH, temperature, enzyme concentration, etc.). In the treatment of rheumatoid arthritis, common administration routes for hydrogel drug delivery systems include parenteral administration, oral administration, transdermal administration, and intra-articular injection, which significantly reduce systemic adverse reactions, improve drug absorption efficiency, and enhance patient compliance. Although hydrogel systems as drug delivery carriers have shown significant application potential in the treatment of rheumatoid arthritis, long-term safety, biodegradability, and large-scale production still need to be addressed to promote the clinical translation of hydrogel drug delivery carriers.
