Low (Specialist)Technical/Medical
Definition
Meaning
A medication that inhibits the breakdown of acetylcholine, used primarily to treat myasthenia gravis and to reverse certain muscle relaxants in anaesthesia.
A synthetic anticholinesterase agent, often administered as a bromide or methylsulfate salt, which enhances neuromuscular transmission by prolonging the action of acetylcholine.

Examples
By CEFR Level
- The doctor gave her a new medicine.
- After the operation, they gave him a drug to help his muscles work again.
- The anaesthetist administered neostigmine to reverse the effects of the muscle relaxant.

Memory Aids
Mnemonic
Think of 'NEO' (new) and 'STIGMA' (mark). A new mark of improvement for muscle strength in myasthenia gravis.

Common Pitfalls
Translation Traps (for Russian speakers)
- May be transliterated directly as 'неостигмин', a precise equivalent. No false friends, but ensure correct anatomical/physiological context is understood.
Common Mistakes
- Misspelling as 'neostigmin' (dropping the final 'e').
- Mispronouncing with stress on the first syllable (/ˈniːoʊ/).
- Confusing it with 'physostigmine', a related but different alkaloid.

FAQ
Frequently Asked Questions
No, neostigmine is not an analgesic. It is an anticholinesterase medication used to improve muscle strength or reverse specific muscle relaxants.
Yes, it is available in oral tablet form (typically as the bromide salt) for the chronic management of conditions like myasthenia gravis.
Neostigmine's action increases acetylcholine levels throughout the body, which can cause undesirable side effects like bradycardia (slow heart rate) and excessive secretions. Atropine or glycopyrronium are anticholinergics given to block these muscarinic effects.
Common side effects are related to its cholinergic action and can include nausea, vomiting, diarrhoea, abdominal cramps, increased salivation, sweating, and muscle twitching.
