4 syllables: an, as, tro, zole. Stress on as.
uh-NAS-troh-zohl
/ənˈæs troʊ zoʊl/
anastrozole is pronounced uh-NAS-troh-zohl (/ənˈæs troʊ zoʊl/). It has four syllables (an-as-tro-zole), with the stress on "as". Anastrozole is a nonsteroidal aromatase inhibitor used in hormone-responsive breast cancer treatment. It suppresses estrogen production by blocking the aromatase enzyme, helping to slow or halt tumor growth. In medical contexts, it’s discussed with clinicians, pharmacists, and patients regarding dosing, side effects, and treatment planning.

- You: 2-3 phonetic challenges: 1) Middle consonant cluster 'str' can blur into 'nas-tr' or 'nas-tro' depending on pace. 2) Final vowel length: avoid shortening /zoʊl/ to /zol/ or dropping the terminal vowel entirely. 3) Stress drift: prevent shifting primary stress to the first syllable; keep it on the second. Corrections: 1) Practice the exact cluster /str/ with a quick, crisp release; 2) hold the final vowel longer when saying 'zole'; 3) rehearse the second syllable with a steady emphasis while keeping the rest neutral.
"The patient was prescribed anastrozole as part of adjuvant therapy."
"In clinical trials, anastrozole showed comparable efficacy with fewer adverse events than some chemotherapies."
"Pharmacists double-check prescriptions to ensure correct anastrozole dosing and interactions."
US: ə-ˈnæs-tro-ˌzɔl; UK: ə-ˈneɪ-strə-ˌzəʊl; AU: ə-ˈnæs-trə-ˌzɔːl. It places primary stress on the second syllable-ish segment “nas/stra” with a clear zw- or str- onset after the initial “ə” vowel. Mouth positions: start with a neutral schwa, then a short a as in cat, then a soft “stro” cluster, finally “zol” with the z sound and a rounded o. Think: uh-NAS-tro-zole. Audio reference: consult Cambridge or Forvo for speaker variants.
Common errors: misplacing stress on the first or last syllable; mispronouncing the ‘str’ cluster as separate sounds (uh-NAS-truh-zawl vs. uh-NAS-tro-zol); softening the final ‘-zole’ to ‘-zone’ or ‘-zol’ without clear z. Corrections: place primary stress on the second syllable roughly ‘nas’; keep the ‘stro’ as a single cluster; ensure the final –zole ends with a voiced z and long o, not a tense ‘oh-l’.
US pronunciation tends to /əˈnæstrəˌzoʊl/ with a clear schwa then ‘nas’ and long o. UK often uses /əˈneɪstrəˌzəʊl/, with a longer first vowel in the second syllable and a non-rhotic r-like effect. Australian similarly reduces the 'a' to a near-schwa, but vowels can be broader; final vowel tends toward a closed 'oʊl' or 'əʊl' depending on speaker. In all variants, the /z/ is voiced; the key variance is the middle vowel quality and the final vowel length.
Two main challenges: the multi-consonant stem “nastro” with the /str/ cluster can trip learners; and the final -zole has a long vowel and a voiced z that must stay clearly separate from the following syllable. Another challenge is maintaining correct stress across fast speech. Focusing on the mid syllable vowel and keeping the final /zɔl/ or /zəʊl/ intact helps reduce mispronunciations.
A useful tip: think of it as a three-part structure: a-schwa + NAS cluster + tro + zol, with the nucleus often slightly reduced in rapid speech. The central syllable often carries the perceptual weight; ensure the /z/ in -zole remains voiced and the final vowel isn’t dropped in casual speech. IPA guides show the core phonemes: /əˈnæstrəˌzoʊl/ (US) or /əˈneɪstrəˌzəʊl/ (UK).

- US: /əˈnæstrəˌzoʊl/ – rhotic-free R, shorter 'ə' and 'æ' clarity. - UK: /əˈneɪstrəˌzəʊl/ – non-rhotic, more diphthong in the second vowel, final /əʊl/. - AU: /əˈnæstroʊzɔːl/ or /əˈneɪstrəˌzɔːl/ – vowel shifts but keep final long o or ɔː depending on speaker. Tips: practice minimal pairs to hear vowel shifts: a vs æ, æ vs eɪ, oʊ vs ɔː. Use IPA as your guide, and record yourself.
Anastrozole is derived from the stem an- (neutral or lacking) and -astro- (relating to stars or a reference to aromatase’s enzyme names) combined with -zole, a chemical suffix used in azole antifungals and related aromatase inhibitors. The term reflects its class (azole derivatives) and function (enzyme inhibition). The word emerged in pharmaceutical literature in the 1990s as selective aromatase inhibitors were developed for postmenopausal breast cancer therapy. It was coined to differentiate from older diets and steroids, emphasizing targeted inhibition rather than broad cytotoxicity. First known usage appears in drug development reports and clinical trial publications around mid-to-late 1990s, with steady adoption in medical practice since the turn of the century. Over time, “anastrozole” became a standard generic name governed by the International Nonproprietary Names (INN) system, distinct from trade names like Arimidol or Arimidex. The etymology thus tracks a confluence of pharmacology taxonomy (azole class) and therapeutic mechanism (aromatase inhibition) rather than any literal linguistic roots in common language.
