When an acetylcholinesterase (AChE) inhibitor binds with acetylcholinesterase, regardless of whether it is reversible or irreversible, it prevents the ability of AChE to bind with acetylcholine (ACh) and break it down. Therefore, ACh accumulates in the synaptic gap, causing the postsynaptic neuron or muscle cell to fire/contract repeatedly. As this happens, a fatigue effect is reached due to depletion of chemical energy stores (ATP, etc.), and weakness results from the reduced ability of neurons/muscles to respond to further stimulation.
The mechanism of acetylcholinesterase (AChE) inhibitor side effects such as weakness is due to excessive accumulation of acetylcholine at cholinergic synapses. This leads to overstimulation of muscarinic and nicotinic receptors, causing symptoms like muscle weakness. The excess acetylcholine can also affect neuromuscular junction function, contributing to weakness.

Yes. Sometimes his stomach hurts.
What will happen if lack of acetylcolinesterase in the synaptic cleft?
Neurotransmitters would continue to bind and rebind with the postsynaptic receptors, which would continue induction of a signal in the postsynaptic neurons, which would repropagate the initial signal. The case in drugs that block reuptake transporters (such as in serotonin reuptake inhibitor and norepinephrine reuptake inhibitor antidepressants, and dopamine reuptake inhibition found with cocaine and methylphenidate). This is also seen in cases where drugs block the breakdown of neurotransmitters at the synapse: - monoamine oxidase inhibitors (MAOIs) - Nardil, Parnate, selegiline - which prevent the breakdown of serotonin, norepinephrine, and dopamine - acetylcholinesterase inhibitors (AChE inhibitors) - organophosphase pesticides, nerve gas, racetams

This typically happens in old and gold people. Children do not get it. They continue to play during fever also.

How can a cholinesterase inhibitor improve mental function in Alzheimers disesae?
Essentially a lot of the pathways affected in AD are run by AceylCholine so a central ACHE inhibitor would allow increased ACH in the CNS and bypass the damage that may be inhibiting the synaptic transmission. This is all theoretical of course. Kevin
What is the role of acetylcholinesterase to acetylcholine?
The acetylcholinesterase (AChE) essentially works against acetylcholine (ACh). AChE will break up the ACh into its two main groups, acetate and choline so that it is not able to do its job. (In the case of certain diseases, like Alzheimer's, AChE can result in negative effects, and drugs are given to prevent the action of AChE.)

How is neostigmine chemically used to treat myasthenia gravis?
Neostigmine is a competitive irreversible inhibitor of Acetylcholinesterase (AChE), an enzyme responsible for breaking down acetylcholine (ACh). Myasthenia gravis is caused by the body producing too little ACh receptors. As stimulating the ACh receptors is needed for nervous transmission, the nerve signals cannot be transmitted causing muscle weakness and fatigue. Neostigmine is hence used to inhibit AChE so that less ACh gets broken down. This leads to more ACh binding to the ACh receptors causing muscular contraction.
