Cholinesterase (ChE) is a family of enzymes present in the central nervous system, particularly in nervous tissue, muscle and red cells, which catalyze the hydrolysis of the neurotransmitter acetylcholine into choline and acetic acid, a reaction necessary to allow a cholinergic neuron to return to its resting state after activation. It is one of many important enzymes needed for the proper functioning of the nervous systems of humans.

There are two types: acetylcholinesterase (AChE, acetylcholine hydrolase) and butyrylcholinesterase (BChE, acylcholine acylhydrolase), also known as nonspecific cholinesterase or pseudocholinesterase. AChE is primarily found in the blood on red blood cell membranes, in neuromuscular junctions, and in neural synapses, while BChE is produced in the liver and found primarily in plasma. The difference between the two types of cholinesterase is their relative preferences for substrates: AChE hydrolyzes acetylcholine faster while BChE hydrolyzes butyrylcholine faster.

    Echothiopate chloride
    		Inhibitor
    Echothiophate (Echothiophate) chloride is a highly effective, long-lasting cholinesterase inhibitor employed as a miotic for managing glaucoma. Echothiopate chloride forms a covalent bond with the serine residue at the active site of cholinesterase through its phosphate group, rendering the enzyme permanently inactive and necessitating the synthesis of new enzymes by the cell. Given its irreversible binding to cholinesterase and the extremely slow rate of hydrolysis, the effects of echothiophate can persist for a week or longer. Echothiopate chloride is utilized as an ocular antihypertensive agent in the treatment of chronic glaucoma and, in certain cases, accommodative esotropia.
