Rheumatoid arthritis treatment using hydroxychloroquine and methotrexate co-loaded nanomicelles: In vivo results. Academic Article uri icon


  • Rheumatoid arthritis (RA) is the most common inflammatory rheumatic disease, affecting almost 1% of the world population. It is a long-lasting autoimmune disease, which mainly affects the joints causing inflammation and swelling of the synovial joint. RA has a significant impact on the ability to perform daily activities including simple work and household chores. Nonetheless, due to the long periods of pain and the continuous use of anti-inflammatory drugs, RA can debilitate the quality of life and increases mortality. Current therapeutic approaches to treat RA aim to achieve prolonged activity and early and persistent remission of the disease, with the gradual adoption of different drugs available. In this study, we developed a novel hydroxychloroquine and methotrexate co-loaded Pluronic F-127 nanomicelle and evaluated its therapeutic effects against RA. Our results showed that drug-loaded nanomicelles were capable of modulating the inflammatory process of RA and reducing osteoclastogenesis, edema, and cell migration to the joint. Overall, compared to the free drugs, the drug-loaded nanomicelles showed a 2-fold higher therapeutic effect.
