Cholinergic Receptor Inhibitors Class/mechanism Flashcards
Atropine
Tertiary amine antimuscarinic
blocks muscarinic receptors
scopolamine (transderm-scop)
Tertiary amine antimuscarinic
blocks muscarinic receptors
Dicyclomine (Bentyl)
Tertiary amine antimuscarinic
blocks muscarinic receptors
Tropicamide (mydriacyl)
Tertiary amine antimuscarinic
blocks muscarinic receptors
Tolterodine (detrol)
Tertiary amine antimuscarinic
blocks muscarinic receptors
Benztropine (Cogentin)
Tertiary amine antimuscarinic
blocks muscarinic receptors
Ipratropium (Atrovent)
Quaternary amine antimuscarinic
blocks muscarinic receptors
Tiotropium (spiriva)
Quaternary amine antimuscarinic
blocks muscarinic receptors
Hexamethonium (Methium)
Ganglionic blocker
blocks ganglionic Nn/N2 receptor and sympathetic tone
Mecamylamine
ganglionic blocker (Crosses BBB) blocks ganglionic Nn/N2 receptor and sympathetic tone
Succinylcholine (Anectine)
Depolarizing blocker
overstimulation of nicotinic receptor, leading to desensitization of muscle unit to further ACh stimulation
Tubocurarine (Curare)
Nondepolarizing blocker
blocks nicotinic Nm/N1 receptor
Mivacurium (Mivacron)
Nondepolarizing blocker
blocks nicotinic Nm/N1 receptor
Botulinum toxin A (Botox)
Local paralytic
Blocks vesicle fusion and ACh release on presynaptic terminal by degrading SNAP-25
