Methotrexate (MTX), formerly known as amethopterin, is a chemotherapy agent and immune system suppressant. It is used to treat cancer, autoimmune diseases, ectopic pregnancy, and for medical abortions. Types of cancers it is used for include breast cancer, leukemia, lung cancer, lymphoma, and osteosarcoma. Types of autoimmune diseases it is used for include psoriasis, rheumatoid arthritis, and Crohn's disease. It can be given by mouth or by injection.Common side effects include nausea, feeling tired, fever, increased risk of infection, low white blood cell counts, and breakdown of the skin inside the mouth. Other side effects may include liver disease, lung disease, lymphoma, and severe skin rashes. People on long-term treatment should be regularly checked for side effects. It is not safe during breastfeeding. In those with kidney problems, lower doses may be needed. It acts by blocking the body's use of folic acid.

Medical uses

Chemotherapy
Methotrexate was originally developed and continues to be used for chemotherapy, either alone or in combination with other agents. It is effective for the treatment of a number of cancers, including: breast, head and neck, leukemia, lymphoma, lung, osteosarcoma, bladder, and trophoblastic neoplasms.

Autoimmune disorders
It is used as a disease-modifying treatment for some autoimmune diseases, including rheumatoid arthritis, juvenile dermatomyositis, psoriasis, psoriatic arthritis, lupus, sarcoidosis, Crohn's disease, eczema and many forms of vasculitis.Although originally designed as a chemotherapy drug (using high doses), in low doses, methotrexate is a generally safe and well tolerated drug in the treatment of certain autoimmune diseases. Because of its effectiveness, low-dose methotrexate is now first-line therapy for the treatment of rheumatoid arthritis. Weekly doses are beneficial for 12 to 52 weeks duration therapy, although discontinuation rates are as high as 16% due to adverse effects. Although methotrexate for autoimmune diseases is taken in lower doses than it is for cancer, side effects such as hair loss, nausea, headaches, and skin pigmentation are still common. Use of low doses of methotrexate together with NSAIDS such as aspirin or paracetamol is relatively safe in people being treated for rheumatoid arthritis, if adequate monitoring is done.

Recently, use of methotrexate in combination with anti-TNF agents has been shown to be effective for the treatment of ulcerative colitis.

Methotrexate has also been used for multiple sclerosis.

Abortion
Methotrexate is an abortifacient and is commonly used to terminate pregnancies during the early stages, generally in combination with misoprostol. It is also used to treat ectopic pregnancies, provided the fallopian tube has not ruptured.

Molar pregnancy
Methotrexate with dilatation and curettage is used to treat molar pregnancy.

Dosage

Methotrexate can be given by mouth or by injection (intramuscular, intravenous, subcutaneous, or intrathecal).Doses by mouth are usually taken weekly, not daily, to limit toxicity.Routine monitoring of the complete blood count, liver function tests, and creatinine are recommended. Measurements of creatinine are recommended at least every 2 months.

Side effects

The most common adverse effects include: hepatotoxicity (liver damage), ulcerative stomatitis, leukopenia and thus predisposition to infection, nausea, abdominal pain, fatigue, fever, dizziness, acute pneumonitis, rarely pulmonary fibrosis, and kidney failure. Methotrexate is teratogenic (harmful to a fetus) and hence is not advised for either the prospective father to take it before or for the mother to take it before or during pregnancy (pregnancy category X) and for a period after birth.Methotrexate may increase the risk of certain cancers (lung cancer and melanoma for example), and the risk is believed to be higher for this drug than other disease-modifying anti-rheumatic drugs (DMARDS)).

Central nervous system reactions to methotrexate have been reported, especially when given via the intrathecal route (directly into the cerebrospinal fluid), which include myelopathies and leucoencephalopathies. It has a variety of cutaneous side effects, particularly when administered in high doses.

Another little understood but serious possible adverse effect of methotrexate is neurological damage and memory loss. Neurotoxicity may result from the drug crossing the blood-brain barrier and damaging neurons in the cerebral cortex. People with cancer who receive the medication often nickname these effects "chemo brain" or "chemo fog".

Drug interactions

Penicillins may decrease the elimination of methotrexate, so increase the risk of toxicity. While they may be used together, increased monitoring is recommended. The aminoglycosides, neomycin and paromomycin, have been found to reduce gastrointestinal (GI) absorption of methotrexate. Probenecid inhibits methotrexate excretion, which increases the risk of methotrexate toxicity. Likewise, retinoids and trimethoprim have been known to interact with methotrexate to produce additive hepatotoxicity and haematotoxicity, respectively. Other immunosuppressants like ciclosporin may potentiate methotrexate's haematologic effects, hence potentially leading to toxicity.NSAIDs have also been found to fatally interact with methotrexate in numerous case reports.Nitrous oxide potentiating the haematological toxicity of methotrexate has also been documented. Proton-pump inhibitors such as omeprazole and the anticonvulsant valproate have been found to increase the plasma concentrations of methotrexate, as have nephrotoxic agents such as cisplatin, the GI drug colestyramine, and dantrolene.
