MAXTREX is a brand name for methotrexate, a medication widely used in the treatment of various medical conditions, including certain types of cancer, rheumatoid arthritis, and psoriasis. Methotrexate belongs to a class of drugs known as antimetabolites, which work by inhibiting the metabolism of cells, thereby slowing or stopping their growth. In the context of cancer treatment, it targets rapidly dividing cancer cells to prevent their proliferation. For autoimmune diseases like rheumatoid arthritis and psoriasis, methotrexate helps to reduce inflammation and slow down the progression of the disease by modulating the immune system. It is available in various forms, including tablets and injections, and its use must be closely monitored by a healthcare provider due to its potential for causing serious side effects.
