DMARDs are used to delay the progression of rheumatoid arthritis. DMARDs have different mechanisms of action and are often used in combination therapy. Although the mechanism of action varies, they have a similar impact on the disease process. Biologic response modifiers are genetically engineered and work by interrupting a patient’s immune system signals that are responsible for tissue damage. Most of these medications attempt to interfere with the activity of tumor necrosis factor. Glucocorticoids are used to reduce inflammation and also to curb the autoimmune activity. They are often used in conjunction with DMARDs. NSAIDs can aid with pain control, swelling, and inflammation, but do not affect slowing the disease process. Analgesics are used to control pain only.
