Methotrexate is pronounced meth-oh-TREK-sayt (/ˌmɛθoʊˈtɹɛˌkseɪt/). It has four syllables (Me-tho-tre-xate), with the stress on "tre". Methotrexate is a cytotoxic antineoplastic and antimetabolite medication used to treat certain cancers and autoimmune diseases by inhibiting dihydrofolate reductase. It interferes with DNA synthesis and cell replication, often administered in high-dose regimens or as part of combination therapies. Physicians monitor dosing closely due to potential toxicity and interactions with other drugs.

"The oncologist prescribed methotrexate as part of the chemotherapy protocol."
"In rheumatoid arthritis, low-dose methotrexate is commonly used to reduce joint inflammation."
"Methotrexate can cause liver enzyme elevations, so regular blood tests are required."
Pronounce as muh-THO-trek-sate, with primary stress on the second syllable. IPA US: /ˌmɛθəˈtrɛksˌeɪt/; UK: /ˌmiːθəˈtrɛksˌeɪt/; AU: /ˌmiːˈθɒtrɛksˌeɪt/. Break it into three parts: mes- and meth- start with a soft 'm', 'tho' like 'tho' in 'though', and 'trex' like 'treks', trailing 'ate' as in 'eight'.
Common errors: stressing the wrong syllable (placing primary stress on the first or third syllable), mispronouncing 'trex' as 'treaks' with a long 'a', and flattening the final 'ate' to an 'at' sound. Correct by practicing: /ˌmɛθəˈtrɛksˌeɪt/ or /ˌmiːˈθəˈtrɛksˌeɪt/ depending on variant, ensuring clear 'th' as /θ/ and final /eɪt/ rather than /eɪt/ with too-short vowel.
In US, the initial 'me-' often reduces to /mɛ/ with less emphasis on 'm', while the second syllable carries strong stress: /ˌmɛθəˈtrɛksˌeɪt/. UK tends to a clearer /miːθə/ onset with slightly longer vowel in 'me', but still strong on 'trex'. Australian pronunciations resemble UK with a potential diphthong shift in the final 'ate' to /eɪt/ and rhoticity less pronounced in non-rhotic speech, producing /ˌmiˈθɒtrɛksˌeɪt/ in some speakers.
The difficulty stems from the three-syllable, multi-consonant cluster with a soft 'th' (/θ/), the 'trex' cluster with 'tr' onset, and a multi-letter final syllable '/eɪt/'. The stress pattern can vary in clinical speech, and non-native readers may misplace the secondary stress or mispronounce the ‘x’ as /ks/ or /z/. Practice with IPA and mimic native rhythm to stabilize the sequence.
A distinctive aspect is the combination of a dental-alveolar fricative /θ/ (as in bath) followed by a moving 'tro' cluster, requiring a light middle vowel /ə/ before the strong /trɛk/. The final '/eɪt/' is a strong, tense diphthong that should not be reduced in rapid speech. Focusing on the 'trex' as a single unit helps avoid splitting it into 'tr-ex'.

Methotrexate derives from a combination of genetic roots and chemical naming conventions. The base 'meth-' suggests a methyl group, while '-otrexate' aligns with other antimetabolite drugs in which 'trex-' evokes a triadic or repetitive chemical substructure pattern seen in folate pathway inhibitors. The term was coined in the mid-20th century as synthetic folate antagonists were developed for cancer chemotherapy. It entered medical lexicon as a compound used to disrupt purine and thymidine synthesis, important for DNA replication. The first successful uses emerged in the 1950s and early 1960s in pediatric leukemia trials and later in broader oncology. The drug was marketed in various salt forms and brand names, with 'Methotrexate' becoming the standard generic descriptor across diverse therapeutic indications. The evolution of its pharmacologic identity is tied to the broader history of antifolates, where structural similarity to folic acid allows competitive inhibition of dihydrofolate reductase. Its challenging dosing regimens and toxicity profile have influenced the development of rescue protocols and monitoring guidelines in modern medicine.
