<unk>  (sold under the trade name Exelon among others) is a cholinesterase inhibitor used for the treatment of mild to moderate Alzheimer's disease.

The drug is eliminated through the urine, and appears to have relatively few drug-drug interactions. It was patented in 1985 and came into medical use in 1997.
