The treatment methods for rheumatoid arthritis mainly fall into three categories: The first category is anti-inflammatory analgesics, which include non-steroidal analgesic drugs such as slow-release diclofenac sodium. For patients with especially high inflammatory indicators, low-dose corticosteroids may also be considered. The second category of drugs includes slow-acting drugs commonly used in the treatment of rheumatoid arthritis, such as methotrexate and leflunomide, which are immunosuppressants. If the patient does not respond well to non-steroidal analgesic drugs or immunosuppressants, biological agents can be considered as a treatment option. Common biological agents include tumor necrosis factor antagonists. (Specific medications should be taken under the guidance of a physician.)
