4 syllables: lo, pi, na, vir. Stress on pi.
loh-PIN-uh-vur
/loʊˈpɪnəvɚ/
lopinavir is pronounced loh-PIN-uh-vur (/loʊˈpɪnəvɚ/). It has four syllables (lo-pi-na-vir), with the stress on "pi". Lopinavir is an antiretroviral protease inhibitor used in combination therapy for HIV treatment. It functions by blocking the HIV protease enzyme, thereby preventing viral maturation. This term appears mainly in medical contexts, pharmacology discussions, and clinical guidelines, often paired with ritonavir to boost efficacy.

"The patient was prescribed lopinavir/ritonavir as part of their antiretroviral regimen."
"Pharmacists noted a potential drug interaction between lopinavir and certain statins."
"Clinical trials assessed lopinavir exposure in relation to liver enzyme levels."
Pronounce as lo-PIN-ah-veer, with primary stress on the second syllable. IPA: US / loʊˈpiː.nə.vɜːr /, UK / lɒˈpɪ.nə.vɪə /, AU / ˈləʊ.pɪ.nə.vɜː /. Focus on a clear ‘lo’ initial, a strong secondary cluster in ‘pi’ and a light, two-consonant end '-vir' that touches a light 'r' in many accents. For audio reference, imagine slow, deliberate medical diction and imitate a pharmacist reading drug labels.
Common errors: (1) Stress misplacement, placing main stress on the first syllable (lo-PIN-a-vir vs LO-pi-NA-vir). (2) Vowel quality in the first syllable where 'lo' is pronounced like 'low' rather than a clipped 'lo' sound. (3) Final '-vir' pronounced as 'veer' vs a clipped 'vir' with a softer 'r' in non-rhotic accents. Corrections: keep primary stress on the second syllable, use a short 'o' in 'lo', and end with a clear 'vir' without overemphasizing the 'r' in non-rhotic contexts.
US speakers tend to a clear 'lo-PEE-nə-vir' with a strong 'r' at the end in rhotic contexts. UK speakers may reduce the vowel in the first syllable and stress the second: 'LO-pi-nə-və' or 'lo-PIN-uh-veer' depending on speaker. Australian English generally features a clearer 'v' followed by a more centralized or non-rhotic 'r'—'LOH-pi-nuh-veer' or 'loh-PEE-nuh-veh' with slight vowel broadening. IPA guidance: US / loʊˈpiː.nə.vɜːr/, UK / lɒˈpɪ.nə.vɪə/, AU / ˈləʊ.pɪ.nə.vɜː /.
Two main challenges: the non-native-friendly consonant cluster ending '-nə-vir' blends quickly, and the second syllable 'pi' often carries the peak of the word’s rhythm, so speakers may misplace stress there. The resemblance to other '-navir' drugs tempts simplification, and the 'lo' vowel in some languages leans toward a lax vowel. Focus on the two-segment syllable with precise vowel height and the aspirated 'v' preceding the 'ir' end. IPA cues help anchor the sounds.
A common unique point is the potential confusion between the 'pi' and 'ni' sequences in fast speech. Ensure you articulate 'pi' with a long 'ee' quality in many transcriptions (as in 'pea') and then glide into the 'ni' with a light 'n' to avoid the 'vir' being swallowed. In careful medical speech, the word often splits into three clear syllables lo-PIN-a-vir, with peak stress on PIN. IPA references can help track the exact vowels across dialects.

Lopinavir derives from a systematic naming pattern for protease inhibitors, combining a stem that signals protease inhibition with a suffix that often evinces medicinal chemistry roots. The first part, 'lopin-,' does not have a transparent standalone meaning in the literature but aligns with other HIV protease inhibitors in conveying a medicinally active compound. The suffix '-navir' is common among protease inhibitors and is phonetically linked to the broader class names used by regulatory bodies and pharmacology texts. The term entered medical lexicon in the early 2000s as combination therapies were developed to enhance antiretroviral potency and reduce resistance. The naming pattern mirrors earlier HIV protease inhibitors like ritonavir and saquinavir, though lopinavir itself was formulated to optimize oral bioavailability when combined with ritonavir. The first known uses appear in clinical trial reports and drug labeling, where pharmacokinetics and interaction profiles with ritonavir were described to maximize therapeutic outcomes. Over time, lopinavir gained prominence in guidelines for antiretroviral therapy regimens, particularly in resource-limited settings, with ongoing research into dosing strategies, metabolic effects, and tolerability. The etymology reflects regulatory naming conventions and the pharmaceutical industry’s tendency to reuse the ‘-navir’ suffix to signal a protease-inhibiting mechanism.
