ISBN 978-0-444-52166-8. Cholinomimetics or cholinergic drugs are those drugs that cause effects similar to those resulting from introduction of acetylcholine, or simulation of ganglions of the parasympathetic nervous system. These drugs imitate action of endogenously released acetylcholine.
A parasympathomimetic drug, sometimes called a cholinomimetic drug[ 1] or cholinergic receptor stimulating agent, [ 2] is a substance that stimulates the parasympathetic nervous system (PSNS). [ 3][ 2] These chemicals are also called cholinergic drugs because acetylcholine (ACh) is the neurotransmitter used by the PSNS. [ 1][ 4] Chemicals in ...
Cholinergic blocking drugs are a group of drugs that block the action of acetylcholine (ACh), a neurotransmitter, in synapses of the cholinergic nervous system. [1] They block acetylcholine from binding to cholinergic receptors, namely the nicotinic and muscarinic receptors. These agents have broad effects due to their actions in nerves located ...
Neuromuscular-blocking drugs, or Neuromuscular blocking agents ( NMBAs ), block transmission at the neuromuscular junction, [ 1] causing paralysis of the affected skeletal muscles. This is accomplished via their action on the post-synaptic acetylcholine (Nm) receptors. In clinical use, neuromuscular block is used adjunctively to anesthesia to ...
Cholinesterase inhibitors (ChEIs), also known as anti- cholinesterase, are chemicals that prevent the breakdown of the neurotransmitter acetylcholine or butyrylcholine. This increases the amount of the acetylcholine or butyrylcholine in the synaptic cleft that can bind to muscarinic receptors, nicotinic receptors and others.
Flaccid paralysis resulting from cholinergic crisis can be distinguished from myasthenia gravis by the use of the drug edrophonium (Tensilon), as it only worsens the paralysis caused by cholinergic crisis but strengthens the muscle response in the case of myasthenia gravis. (Edrophonium is a cholinesterase inhibitor, hence increases the ...
Nicotinic antagonist. A nicotinic antagonist is a type of anticholinergic drug that inhibits the action of acetylcholine (ACh) at nicotinic acetylcholine receptors. These compounds are mainly used for peripheral muscle paralysis in surgery, the classical agent of this type being tubocurarine, [ 1] but some centrally acting compounds such as ...
The muscarine cholinergic receptor activates a G-protein when bound to extracellular ACh. The alpha subunit of the G-protein activates guanylate cyclase (inhibiting the effects of intracellular cAMP) while the beta-gamma subunit activates the K-channels and therefore hyperpolarize the cell. This causes a decrease in cardiac activity.
