A shortage in tetrahydrofolic acid (FH4) can cause megaloblastic anemia. [2] [3] [4] Methotrexate acts on dihydrofolate reductase, like pyrimethamine or trimethoprim, as an inhibitor and thus reduces the amount of tetrahydrofolate made. This may result in megaloblastic anemia.
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.
Red blood cells normally survive an average of about 120 days, becoming damaged (their oxygen-carrying capacity becomes compromised) as they age.
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.
