Very lowTechnical/Scientific/Medical
Definition
Meaning
An antiretroviral drug used in the treatment of HIV/AIDS.
A thymidine analogue that inhibits the replication of the human immunodeficiency virus (HIV) by interfering with the viral enzyme reverse transcriptase, thereby slowing disease progression. It is a nucleoside reverse transcriptase inhibitor (NRTI).
Linguistics
Semantic Notes
Almost exclusively used within medical and pharmacological contexts. It has a proprietary name ('Retrovir') and the chemical name 'azidothymidine' (AZT). The term denotes a specific chemical entity rather than a general class.

Examples
By CEFR Level
- Zidovudine is an important medicine for HIV.
- The doctor explained that zidovudine can have some side effects, like nausea or headache.
- AZT, also known as zidovudine, was a breakthrough in AIDS treatment in the 1980s.
- The clinical trial compared the efficacy of the new protease inhibitor against a backbone regimen containing zidovudine.
- Resistance to zidovudine develops through specific mutations in the HIV reverse transcriptase gene.
Learning
Memory Aids
Mnemonic
Think: 'ZIDs Over VUdine' – a ZID (like a rapid action) overcomes the VU (Virus) in a medicinal 'dine' (like medicine). It's AZT, the first AZTack on HIV.
Conceptual Metaphor
A BLOCKER/SHIELD: The drug is conceptualized as a chemical agent that blocks or inhibits the virus's replication machinery.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with general terms like 'препарат' or 'лекарство'. It is specifically 'зидовудин'.
- The abbreviation 'AZT' (азидотимидин) is also used in Russian medical contexts.
- Avoid literal translation of parts of the word; it is an established international nonproprietary name (INN).
Common Mistakes
- Mispronunciation: stressing the first syllable (ZI-dovudine) is common but incorrect; stress is typically on the second syllable.
- Misspelling: 'zidovudin' (missing final 'e'), 'zidovudina'.
- Using it as a general term for all HIV medication.
