Nanostructured lipid carriers in Rheumatoid Arthritis: treatment, advancements and applications.

Rheumatoid arthritis (RA) is a chronic autoimmune disease that affects the joints and causes pain, swelling, and deformity. Current treatments, including nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and disease-modifying antirheumatic drugs, often have limited efficacy and adverse side effects. Nanostructured lipid carriers (NLCs) are promising drug delivery agents for treating RA.
