Introduction:
Methotrexate 5 mg is a medication that belongs to the class of drugs known as antimetabolites. It is commonly used in the treatment of various conditions, including cancer, autoimmune diseases, and ectopic pregnancy. Methotrexate works by interfering with the growth of certain cells in the body, particularly those that are rapidly dividing.
Active Ingredients:
The active ingredient in Methotrexate 5 mg is methotrexate itself. Methotrexate is a folic acid antagonist, which means it inhibits the metabolism of folic acid in the body. This disruption in folate metabolism ultimately leads to the suppression of cell growth and replication.
Pharmacological Properties:
Methotrexate exerts its pharmacological effects by inhibiting the enzyme dihydrofolate reductase, which is essential for the synthesis of DNA, RNA, and proteins. By interfering with these crucial processes, Methotrexate effectively halts the proliferation of rapidly dividing cells, such as cancer cells or cells of the immune system in autoimmune diseases.
