Acetylcholinesterase inhibitors: Reversible:1.Physostigmine -Miotic, cycloplegic and reduces IOT 0.25-0.5 % drops -Atropine, and antidepressant poisoning with predominant CNS manifestations (crosses BBB) 2.Neostigmine-Doesnt cross BBB, hence good for d.tubocurare muscle blockade -Myasthenia -Post op ileus -Decurarisation 3.Pyridostigmine-Similar but less potent and long acting than neostigmine. Better tolerated in myasthenic patients 4.Edrophonium -Dx of myasthenia -Cobra bites 5.Rivastigmine -Alzhiemers(?) Irreversible: -Mostly pesticides DFP,Malathoin,Parathoin,Sarin, Soman (Nerve gas) -Metrifonate(Antihelminthic drug)
What else can I help you with?
Mechanism of action of neostigmine?
There are 3 different types of acetylcholinesterase inhibitors - short-acting, medium-duration and irreversible inhibitors, which differ in their interactions with the active site of acetylcholinesterase.=Neostigmine is a medium-duration acetylcholinesterase inhibitor that enhances cholinergic transmission in the central nervous system, autonomic nervous system and at neuromuscular junctions. Acetlycholinesterase inhibitors are an established therapy for Alzheimer's disease and dementia .=
A chemical that keeps food from spoiling is a example of?
it is an example of a inhibitor
What is the mechanism of AchE inhibitor side effects of weakness?
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.
How is acetylcholine (ACh) removed from the synaptic cleft?
Acetylcholine is degraded by acetylcholinesterase
What destroys ACh?
Acetylcholinesterase (AChE) is an enzyme that breaks down acetylcholine (ACh) into choline and acetate, thus destroying ACh. This process helps in regulating the levels of ACh at the synaptic cleft and terminating its action.
Is there a sentence which includes the word acetylcholinesterase if so what is it?
"Acetylcholinesterase" production results in the production of a glucosteroid inhibitor.

What is a Acetylcholinesterase inhibitor?
Acetylcholinesterase inhibitors, of course! These include ambinonium (Mytelase), physostigmine, neostigmine (Prostigmin, Vagostigmin), galantamine (Razadyne, Reminyl, Nivalin), pyridostigmine, Tacrin (Cognex), donepezil (Aricept), edrophonium (Tensilon, Enlon, Reversol) and rivastigmine (Exelon), and others.
Can you identify of what kind of drug is physostigmine?
Physostigmine is an inhibitor of acetylcholinesterase which breaks down acetylcholine in the synaptic cleft of the neuromuscular junction. It is used in the treatment of Alzheimer's and memory loss.
What is an example of a MAO-B inhibitor?
Selegiline is an MAO-B inhibitor
What is the antidote of pyridostigmine?
The antidote for pyridostigmine, which is a reversible acetylcholinesterase inhibitor, is atropine. Atropine works by blocking the effects of excess acetylcholine at muscarinic receptors, alleviating symptoms of cholinergic toxicity. In severe cases, pralidoxime may also be administered to help restore normal function of acetylcholinesterase if there is significant inhibition.
A chemical that keeps food from spoiling is a example of?

What is an example of a penicillin mixed with a beta-lactamase inhibitor?
The drug Augmentin, for example, contains a combination of amoxicillin and a betalactamase inhibitor, clavulanic acid.
What is the mechanism of AchE inhibitor side effects of weakness?

Can acetylcholinesterase inhibitor kill you?
Yes it can. Rather painfully too. AChEI is one of the formulations for chemical weaponry, as well as offering some therapeutic effects in treating neurologic disorders.However, it's pretty dangerous and, what's more, painful in overdose.
How do you pronounce acetylcholinesterase?
Acetylcholinesterase is pronounced uh-SEET-uhl-KOH-lin-ES-ter-ays.
What is the name of enzyme which is used for inactivation of neurotransmitter?
There are a number of neurotransmitter deactivators. For example acetylcholinesterase and anticholinesterases. These are 2 of the most important ones.
