About

Methotrexate is an antimetabolite and antifolate drug that works by inhibiting dihydrofolate reductase, an enzyme essential for DNA synthesis, repair, and cellular replication. This action primarily affects rapidly dividing cells, making it effective in treating various cancers, including certain leukemias, lymphomas, and solid tumors. Beyond oncology, methotrexate is also widely used as an immunosuppressant and anti-inflammatory agent in the management of severe autoimmune diseases such as rheumatoid arthritis, psoriasis, and psoriatic arthritis. Its mechanism in these conditions involves modulating immune cell function and reducing inflammatory responses. Due to its potent effects, methotrexate requires careful dosing and monitoring to manage potential toxicities and ensure patient safety.
