Trexan 2.5mg Imported Tablets, commonly associated with the active ingredient Methotrexate, is a highly potent prescription medication used in the treatment of several serious medical conditions including cancer, autoimmune diseases, rheumatoid arthritis, and severe psoriasis. It is classified as an antimetabolite and immunosuppressant drug, meaning it works by interfering with the growth and multiplication of rapidly dividing cells in the body.
In Pakistan, this medicine is available in different imported and local brands under various names such as Trexan, Metrex, Unitrexate, and others, all containing Methotrexate as the active ingredient.
Because of its strong effects on cell growth and immune function, Trexan 2.5mg is not an over-the-counter medication and must only be used under strict medical supervision.
What is Trexan 2.5mg?
