Acectylcholinesterase inhibitors (AchEI; aka anticholinesterase agents) are pharmacological substances that affect the autonomic nervous system by inhibiting acetylcholinesterase, causing acetylcholine to accumulate at cholinergic receptor sites.

Acetylcholinesterase inhibitors work by binding to the anticholinesterase molecule to prevent it from binding of Acetylcholine. " effects are equivalent to stimulation of cholinergic receptors throughout central (if the AchEI crosses the blood brain barrier) and peripheral nervous system " AchE inhibitors can be classified into three different groups:
