atropine
Low-FrequencyTechnical/Medical
Definition
Meaning
A poisonous crystalline alkaloid extracted from plants like deadly nightshade (Atropa belladonna), used medically to dilate pupils, treat certain heart conditions, and as an antidote to some poisons.
A highly potent anticholinergic drug that blocks the action of the neurotransmitter acetylcholine, leading to effects such as increased heart rate, reduced secretions, and pupil dilation. Its use has evolved from a classic poison to a critical medication in emergency and anaesthetic settings.
Linguistics
Semantic Notes
Primarily a technical term from pharmacology and toxicology. In non-specialist contexts, it may be vaguely associated with 'poison' or 'eye drops'. It is a hyponym (specific type) of 'anticholinergic' or 'mydriatic'.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'тропинка' (a path).
- The Russian term 'атропин' is a direct cognate, but ensure correct technical context is maintained.
- In everyday Russian, it might be known as 'капли для глаз' (eye drops), losing the specific drug name.
Common Mistakes
- Misspelling as 'atropin' (dropping the 'e').
- Confusing it with 'atropine sulfate' (the salt form) as if they were different drugs.
- Using it as a countable noun (e.g., 'an atropine') – it is a mass noun.
- Pronouncing it /eɪˈtrəʊpaɪn/ (like 'Atropa' + 'pine') instead of the standard /ˈætrəpiːn/.

FAQ
Frequently Asked Questions
No. Belladonna is the common name for the plant Atropa belladonna. Atropine is the specific, isolated alkaloid compound found in that plant.
Yes. In sufficient doses, atropine is highly toxic and can be fatal, causing delirium, tachycardia, and respiratory failure. Historically, it was indeed used as a poison.
It dilates the pupil (mydriasis) by paralyzing the iris sphincter muscle, allowing the ophthalmologist a better view of the retina.
Yes, but in specific contexts. It remains a critical drug in emergency medicine for symptomatic bradycardia, in anaesthesia as a premedication, and as an antidote for nerve agent and organophosphate poisoning.
