WebBackground: Cholinesterases are a group of serine hydrolases that split the neurotransmitter acetylcholine (ACh) and terminate its action. Of the two types, butyrylcholinesterase and acetylcholinesterase (AChE), AChE plays the key role in ending cholinergic neurotransmission. Cholinesterase inhibitors are substances, either natural or man … WebRivastigmine. Rivastigmine (sold under the trade name Exelon among others) is a cholinesterase inhibitor used for the treatment of mild to moderate Alzheimer's disease. [1] The drug can be administered orally or via a transdermal patch; the latter form reduces the prevalence of side effects, [2] which typically include nausea and vomiting.
