DISEASE-MODIFYING ANTIRHEUMATIC DRUG (DMARD)
Methotrexate is a prescription drug approved by the Food and Drug Administration (FDA) to treat severe cases of psoriasis, rheumatoid arthritis, and some types of cancer. Methotrexate is sometimes prescribed off-label to treat spondylitis. A 2013 review concluded that there is not enough evidence that Methotrexate provides benefits for people with spondylitis. Methotrexate does not improve symptoms in cases of axial spondyloarthritis (axSpA) and is not recommended. However, combining Methotrexate and Adalimumab (Humira) has been associated with long-term maintenance in axSpA. Methotrexate is sold under the brand names Rheumatrex and Trexall.
Methotrexate is an immunomodulator, or drug that modifies the immune system. Methotrexate is a type of disease-modifying antirheumatic drug (DMARD). Methotrexate is believed to suppress the immune system in several ways, reducing the activity of T cells, B cells, interleukins, and enzymes that play a role in autoimmune attacks.
