4 syllables: hy, dra, la, zine. Stress on la.
/haɪdɹəˈleɪziːn/
Say it backHydralazine is a vasodilator medication used to treat high blood pressure. The word is of scientific/medical origin and is pronounced with a three-syllable structure, stressing the second syllable. It combines the hydra- prefix indicating water-related chemistry with the drug suffix -zine, reflecting its pharmacological class, and is typically used in clinical and pharmacological contexts.
"The patient was prescribed hydralazine to control severe hypertension."
"Hydralazine must be monitored for reflex tachycardia and fluid retention."
"In the pharmacology lecture, we discussed hydralazine’s mechanism of arterial dilation."
Hydralazine is pronounced /ˌhaɪ.drəˈleɪ.zɪn/ in US practice, with stress on the third syllable. The initial 'hy' sounds like 'high,' followed by a relaxed 'drah' before the primary stress on 'LEI' and the final 'zine' sounding like 'zin.' In UK usage, it is often /ˌhaɪ.drəˈliː.zɪn/, with a longer 'lee' vowel in the second-to-last syllable. Mouth position: start with a light 'h' followed by a clear 'high' cluster, then a schwa-like 'drə' before the stressed 'leɪ' or 'liː,' and end with 'zin'.
Common errors include stressing the wrong syllable (placing emphasis on 'drah' or 'zine') and mispronouncing the middle vowel cluster. To correct: ensure the primary stress lands on the third syllable 'leɪ' (US) or 'liː' (UK), and pronounce the final '-zine' as /-zɪn/. Avoid turning the r into a rolled or silent consonant; keep it as a light American/neutral /ɹ/ or /ɾ/ depending on dialect. Practice the sequence: /ˌhaɪ.drəˈleɪ.zɪn/ (US) and /ˌhaɪ.drəˈliː.zɪn/ (UK).” ,
In US English, the pronunciation is /ˌhaɪ.drəˈleɪ.zɪn/, with the stressed syllable on -leɪ-. In UK English, it shifts to /ˌhaɪ.drəˈliː.zɪn/, with a longer 'ee' vowel in the second-to-last syllable. Australian English closely mirrors UK, often favoring /ˌhaɪ.drəˈliː.zɪn/ but with a slightly flatter vowel in the second-to-last syllable due to Australian vowel breadth. The rhoticity and vowel quality differences influence the central vowel in the second syllable and the length of the penultimate vowel.
The difficulty comes from the multi-syllabic, medical-chemical construction and the consonant cluster around the mid syllable. The combination of ‘hydra-’ with the ending ‘-zine’ creates potential stress confusion and vowel length variation. You’ll hear tension around the /ˈleɪ/ vs /ˈliː/ in the penultimate syllable, and the final /zɪn/ can be misspoken as /zən/ or /zɪn/. Practice the exact syllable break and stress to stabilize pronunciation.
A hydralazine nuance is the placement of primary stress on the third syllable, yielding /ˌhaɪ.drəˈleɪ.zɪn/ (US) or /ˌhaɪ.drəˈliː.zɪn/ (UK/AUS). The middle vowel can influence listener perception if rushed: ensure /drə/ is a weak, unstressed syllable and that the nucleus of the stressed syllable uses a clear diphthong /eɪ/ or /iː/ depending on dialect. Using a brief pause before the stressed syllable can help accuracy in rapid speech.

US: pronounce with rhotic /ɹ/ and a clear /eɪ/ in the stressed nucleus; mid vowels are reduced. UK: non-rhotic accent; keep /r/ silent, and lengthen the penultimate vowel to /iː/. AU: similar to UK but with a slightly broader, flatter vowel in the second-to-last syllable; maintain the /iː/ or /eɪ/ differentiation depending on speaker. IPA references: US /ˌhaɪ.drəˈleɪ.zɪn/; UK/AU /ˌhaɪ.drəˈliː.zɪn/.
Hydralazine derives from the hydra- element, related to water or liquid in many scientific terms, and the -al- infix linking to chemophysical naming patterns, followed by the -zine suffix common in many aromatic amine drugs. The word likely originated in the mid-20th century as pharmaceutical nomenclature expanded to include synthetic vasodilators. Its immediate linguistic ancestors are rooted in Latinized chemical naming conventions, with hydra- echoing water-derived prefixes and -zine aligning with existing drug nomenclature (e.g., antihistamines and related compounds). The first known uses appear in pharmacology texts and drug development literature from the 1950s–1960s, when new arterial dilators were being identified and named systematically to reflect their chemical class and mechanism. Over time, hydralazine settled into common pharmacological usage, particularly in clinical guidelines and medical discussions about hypertensive management. The term is now widely recognized in medical literature, with pronunciation standardized across English-speaking professional environments, though casual mispronunciations can occur among non-specialists due to its multi-syllabic construct and unfamiliar phoneme cluster. In summary, hydralazine represents a precise, class-based chemical name that entered medical lexicon in the era of modern synthetic vasodilators and has remained a staple in discussions of antihypertensive therapy.
