Disease-moifying antirheumatic drugs (DMARDs) is a category of drugs used in many autoimmune disorders to slow down disease progression. Their use was first propagated in rheumatoid arthritis (hence their name) but has come to include many other diseases, such as Crohn's disease, lupus erythematosus (SLE), idiopathic thrombocytopenic purpura (ITP), myasthenia gravis and various others.
