IPA: //ˌmɛθəʊˈtrɛkseɪt//
KK: /mɛθəˈtrɛkseɪt/
A medication that is used to treat certain types of cancer, severe skin conditions, and inflammatory diseases by blocking the action of folic acid in the body.
The doctor prescribed methotrexate to help manage her rheumatoid arthritis symptoms.
Methotrexate is formed from "meth" (derived from "methyl", meaning a chemical group derived from methane), "o" (a linking vowel), and "trexate" (from "trex", a variant of "trexate", which is derived from "antimetabolite", meaning a substance that interferes with metabolic processes). The word refers to a drug that interferes with the metabolism of cells, particularly in the treatment of cancer and autoimmune diseases.
Think of 'methyl' as a chemical group that plays a role in metabolism, and 'trexate' as a substance that disrupts metabolic processes — together, they describe a drug that affects cell metabolism.
