FOLITREX 2.5 MG

About

Methotrexate (as in FOLITREX) is an antimetabolite and antifolate drug widely used in various medical fields. In oncology, it functions by interfering with DNA synthesis and cell replication, making it effective against certain cancers. At lower doses, it acts as an immunosuppressant and anti-inflammatory agent, primarily by inhibiting dihydrofolate reductase, which leads to the accumulation of adenosine, a potent anti-inflammatory molecule.

This dual action makes methotrexate a cornerstone in the treatment of autoimmune diseases like rheumatoid arthritis, psoriasis, and psoriatic arthritis, where it helps to modulate the immune response and reduce inflammation. Its clinical application requires careful monitoring due to its potential for systemic side effects, necessitating regular blood tests to assess liver function, kidney function, and blood counts.
