METOJECT is a brand name for methotrexate, a medication primarily used in the treatment of certain types of cancer, such as leukemia, breast cancer, and lung cancer, as well as in the management of severe psoriasis and rheumatoid arthritis. Methotrexate belongs to a class of drugs known as antimetabolites, which work by inhibiting the metabolism of folic acid, necessary for cell replication. In the context of cancer treatment, it helps to slow or stop the growth of cancer cells. For autoimmune diseases like rheumatoid arthritis and psoriasis, methotrexate reduces inflammation and slows down the progression of the disease. METOJECT is administered via injection, offering an alternative for patients who may not tolerate oral forms of the medication or require a more direct delivery method for increased efficacy. As with any medication, it is important to use METOJECT under the guidance of a healthcare professional, due to potential side effects and the need for monitoring during treatment.
