Acetylcholine Acetylcholinesterase Acetylcholinesterase inhibition. Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, [1] inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, [2] thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ...
In 1900, Reid Hunt, a pharmacologist (1870-1948), realised a fall in blood pressure in rabbits after removing adrenaline (epinephrine) from adrenal glands extract. While he initially attributed this effect to choline, he later discovered acetylcholine was 100 000 times more potent in lowering blood pressure.
The term "anticholinergic" is typically used to refer to antimuscarinics which competitively inhibit the binding of ACh to muscarinic acetylcholine receptors; such agents do not antagonize the binding at nicotinic acetylcholine receptors at the neuromuscular junction, although the term is sometimes used to refer to agents which do so.

It’s a building block of acetylcholine, an important neurotransmitter that sends messages throughout the brain and nervous system. Studies have linked higher choline intake to better cognitive ...
The enzyme acetylcholine esterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions, in order to allow the muscle or organ to relax. The result of acetylcholine esterase inhibition is that acetylcholine builds up and continues to act so that any nerve impulses are continually transmitted and muscle ...
Acetylcholine is a choline molecule that has been acetylated at the oxygen atom. Because of the charged ammonium group, acetylcholine does not penetrate lipid membranes. . Because of this, when the molecule is introduced externally, it remains in the extracellular space and at present it is considered that the molecule does not pass through the blood–brain
It is therefore classified as an indirect acetylcholine antagonist. [1] Acetylcholine is synthesized from choline and a donated acetyl group from acetyl-CoA, by the action of choline acetyltransferase (ChAT). Thus, decreasing the amount of choline available to a neuron will decrease the amount of acetylcholine produced.
