Description |
Methotrexate is classified as an antimetabolite drug, which means it is capable of blocking the metabolism of cells. As a result of this effect, it has been found helpful in treating certain diseases associated with abnormally rapid cell growth, such as cancer of the breast and psoriasis.
Recently, methotrexate has been shown to be effective in inducing miscarriage, for example in patients with ectopic pregnancy. This effect of methotrexate is attributed to its action of killing the rapidly growing cells of the placenta. It has also been found very helpful in treating rheumatoid arthritis, although its mechanism of action in this illness is not known. It seems to work, in part by altering aspects of immune function which may play a role in causing rheumatoid arthritis.
