idoxuridine
C2Technical, Medical
Definition
Meaning
A synthetic antiviral drug used primarily to treat herpes simplex virus infections of the eye.
A nucleoside analogue (a type of antiviral medication) that inhibits viral DNA replication by being incorporated into the viral DNA chain, causing termination of synthesis. It is specifically used topically for herpes keratitis.
Linguistics
Semantic Notes
This is a highly technical pharmaceutical term. Its use is restricted almost entirely to ophthalmology, virology, and pharmacology contexts. It is not a general-purpose medical term.

Learning
Memory Aids
Mnemonic
Think: "I DO XYlophone URIDINE" - it's an iodine-modified version of uridine (a nucleoside) that you might 'do' as a treatment.
Conceptual Metaphor
A MOLECULAR IMPOSTOR / A SPY IN THE CODE (It mimics a building block of viral DNA but sabotages the replication process).

Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation (идексуридин) would not be recognized by non-specialists. Use the standard international term 'idoxuridine' or the Cyrillic transliteration only in specialist contexts.
- It is not a common over-the-counter drug, so the term has no everyday equivalent.
Common Mistakes
- Misspelling: idoxuridin, idoxyuridine, idxouridine.
- Mispronunciation: placing primary stress on the first syllable (/ˈaɪdɒk.../). Correct stress is on the third syllable.

FAQ
Frequently Asked Questions
It was historically used topically for skin herpes infections, but its primary modern use is for eye infections (keratitis). For cold sores, other antivirals like aciclovir are more common.
No, it is a prescription-only medication in most countries.
It is a nucleoside analogue. The virus mistakenly incorporates it into its DNA during replication, which halts the process and prevents the virus from multiplying.
Local irritation at the site of application (e.g., eye stinging, redness, eyelid swelling) is common. Prolonged use can cause corneal toxicity.
