Acetylcholinesterase inhibitor

An Acetylcholinesterase inhibitor (AChEI) is a type of medication that acts on the nervous system by blocking the enzyme acetylcholinesterase, thus increasing the amount of acetylcholine, a crucial neurotransmitter, in the body.

AChE Mechanism of Action and How phenserine inhibits it

Mechanism of Action

Acetylcholinesterase inhibitors work by binding to and inhibiting the function of acetylcholinesterase, an enzyme responsible for breaking down acetylcholine in the synaptic cleft. By blocking this enzyme, AChEIs increase the level and duration of action of acetylcholine, enhancing cholinergic neurotransmission.

Clinical Uses

Acetylcholinesterase inhibitors are used in the management of several medical conditions. They are most commonly used in the treatment of Alzheimer's disease, myasthenia gravis, and glaucoma. In each of these cases, the goal is to enhance or facilitate neural communication by prolonging the action of acetylcholine.

Side Effects

While acetylcholinesterase inhibitors are beneficial in managing various medical conditions, they may cause side effects. Common ones include nausea, vomiting, diarrhea, and anorexia. In more severe cases, they may cause muscle cramps, bradycardia, or even a severe allergic reaction.
