The current principles of rheumatoid arthritis treatment are to slow down the progression of the disease, reduce complications, and protect joint function. Since rheumatoid arthritis is a heterogeneous disease, the severity of the disease varies from person to person, with some patients experiencing only a few swollen and painful joints, while others have internal organ damage in addition to multiple swollen and painful joints. The mechanism and characteristics of different types of drugs for rheumatoid joints are also different. This also results in differences in the responsiveness of different patients to therapeutic drugs. Therefore, in the treatment of rheumatoid arthritis, there is no such thing as the “best” or “best” drug, but only the most suitable drug for the patient. Therefore, once the diagnosis of rheumatoid arthritis is clear, patients should complete all the tests as soon as possible under the guidance of a rheumatologist, develop a suitable treatment plan, and adjust the dosage and type of medication according to the changes in their condition. The dose and type of medication should be adjusted according to the change of the disease.
