Definition
Meaning and Definition
A substance that inhibits the enzyme cholinesterase, thereby increasing levels of the neurotransmitter acetylcholine.
Any agent, either pharmaceutical drug or chemical, used to block the action of cholinesterase enzymes, leading to increased parasympathetic nervous system activity. Used medically (e.g., for myasthenia gravis, glaucoma) and as toxic nerve agents.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Potential minor spelling preference in derived terms (e.g., 'organisation' vs. 'organization' in institutional names).
Connotations
Identical technical connotations in both varieties.
Frequency
Equally rare and confined to identical specialized fields (neurology, pharmacology, toxicology) in both regions.

Common Mistakes When Using “anticholinesterase”
- Mispronunciation: stressing 'cho' as in 'chocolate' instead of 'ko' as in 'choline'.
- Misspelling: 'anticholinersterase' (missing 'e'), 'anticholineseterase' (transposed letters).
- Using as a verb (e.g., 'to anticholinesterase') – it is almost exclusively a noun.
FAQ
Frequently Asked Questions
No, they are opposites. An anticholinesterase INCREASES acetylcholine (by stopping its breakdown). An anticholinergic BLOCKS acetylcholine receptors, decreasing its effect.
Almost never in standard professional usage. It is predominantly a noun (the agent) or an attributive adjective (e.g., anticholinesterase effect). Using it as a verb is highly non-standard.
No. Their effect depends on dose, specific compound, and context. Some are life-saving medicines (e.g., for myasthenia gravis), while others are lethal nerve agents. The term describes the biochemical action, not the intent or overall toxicity.
Donepezil (Aricept), used in the treatment of Alzheimer's disease, is a common, clinically important example of a reversible anticholinesterase.
A substance that inhibits the enzyme cholinesterase, thereby increasing levels of the neurotransmitter acetylcholine.
Anticholinesterase is usually technical/medical/scientific in register.
Anticholinesterase: in British English it is pronounced /ˌæntiˌkəʊlɪˈnɛstəreɪz/, and in American English it is pronounced /ˌæntiˌkoʊlɪˈnɛstəreɪs/ˌˌæntaɪ-/. Tap the audio buttons above to hear it.

Mnemonic
Think: ANTI-CHOLINE-ESTERASE. It's ANTI (against) CHOLINE (part of acetylcholine) ESTERASE (the enzyme that breaks it down). So, it fights the thing that breaks down an important nerve signal.
Conceptual Metaphor
ENZYME INHIBITOR AS A PLUG/BLOCKER: The anticholinesterase is conceptualized as an object that jams or blocks the active site of the enzyme, preventing it from working.
