Rheumatoid arthritis is a rheumatic immune disease that can cause pain and swelling in multiple joints throughout the body, and can even cause deformation of the joints. Rheumatoid arthritis mainly manifests as chronic wandering joint swelling and pain, mainly in small joints such as fingers and toes, but in severe cases it affects multiple joints throughout the body, and the symptoms worsen after weather changes, exposure to cold, and exertion. It is often accompanied by stiffness and weakness of the hands and feet in the morning, and the symptoms improve with activity. The disease is often recurrent and gradually worsens, gradually leading to joint deformation. Blood tests may reveal elevated rheumatoid factor, anti-cyclic citrulline, blood sedimentation, C-reactive protein and other indicators. Currently, the following types of medications are commonly used: 1, anti-inflammatory and pain-relieving drugs: such as Cilpro, Fotarim, ibuprofen, etc. These drugs can quickly reduce inflammation and pain and relieve symptoms; 2, immunosuppressive drugs: the traditional immunosuppressive drugs include: methotrexate, leflunomide, salazosulfapyridine, raglan, etc. These drugs can stop the occurrence of joint deformation, but the effect is slow (usually takes 3 months to be more effective), and the side effects are more 3, biological agents: in fact, can be defined as a new type of immunosuppressant, the therapeutic effect of this type of drugs compared with traditional drugs has a qualitative leap, not only can quickly and effectively control the disease, and less side effects, but the price is high. Commonly used drugs are: etanercept, infliximab, adalimumab, etc. Patients who have the condition should use them early.
