Methotrexate inhibits cell division and is particularly toxic to fast dividing cells, such as rapidly dividing cancer cells and the progenitor cells of the immune system. Folate supplementation is beneficial in patients being treated with long-term, low-dose methotrexate for inflammatory conditions, such as rheumatoid arthritis (RA) or ...
Low doses of methotrexate can deplete folate stores and cause side-effects that are similar to folate deficiency. Both high-folate diets and supplemental folic acid may help reduce the toxic side-effects of low-dose methotrexate without decreasing its effectiveness.
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 several cancers, including solid tumours of breast, head and neck, lung, bladder, as well as acute lymphocytic leukemias, non-Hodgkin's lymphoma, osteosarcoma, and choriocarcinoma and other trophoblastic neoplasms.
Symptoms of allergic reaction to mercaptopurine include rash, itching, swelling, dizziness, trouble breathing, and inflammation of the pancreas. In some cases, mercaptopurine may suppress the production of blood cells, both white blood cells and red blood cells. It may be toxic to bone marrow. Quarterly blood counts are necessary for people on ...
Maintenance chemotherapy is a repeated low-dose treatment to prolong remission. [5] [6]: 55–59 Salvage chemotherapy or palliative chemotherapy is given without curative intent, but simply to decrease tumor load and increase life expectancy. For these regimens, in general, a better toxicity profile is expected. [6]: 55–59
Symptoms like insomnia can be mediated by making a few smart adjustments to your routine. For example, if you’re prone to insomnia, try taking escitalopram in the morning.
Experimentally, a low dose of methotrexate or cyclosporin and omalizumab (a monoclonal anti-IgE antibody) has been used. Treatment of autoimmune disorders (e.g., SLE) include one or a combination of NSAIDs and hydroxychloroquine, azathioprine, methotrexate, mycophenolate, cyclophosphamide, low dose IL-2, intravenous immunoglobulins, and belimumab.
In conventional chemotherapy, a dose close to the maximum tolerated dose is administered in a bolus manner to achieve cytotoxic effects on tumor cells. [5] However, the side effects are often significant as the cytotoxic agents also kill the fast-dividing cells normally present in the body, such as bone marrow cells and epithelial cells of the gastrointestinal tract.
