Methotrexate
Methotrexate is a critical pharmaceutical compound renowned for its potent antineoplastic and immunosuppressant properties. It plays a pivotal role in treating a wide spectrum of cancers, including acute leukemia, breast cancer, lung cancer, lymphoma, and osteosarcoma, by inhibiting the growth of rapidly dividing cells. Beyond its oncological applications, Methotrexate is a cornerstone in managing autoimmune diseases such as rheumatoid arthritis, psoriasis, and Crohn's disease by modulating the immune system and reducing inflammation. Its efficacy stems from its mechanism as an antifolate, specifically inhibiting dihydrofolate reductase, which is essential for DNA synthesis and cell replication.
- Effective in treating various cancers, including leukemia and breast cancer, by interfering with cancer cell division.
- Manages autoimmune diseases like rheumatoid arthritis and psoriasis by suppressing the immune system's overactivity.
- Utilizes an antifolate mechanism, inhibiting dihydrofolate reductase to disrupt DNA and RNA synthesis.
- Can be administered via multiple routes, including oral, intravenous, intramuscular, and intrathecal injections, offering flexibility in treatment.
