WebMechanism : Succinylcholine is a depolarizing skeletal muscle relaxant. As does acetylcholine, it combines with the cholinergic receptors of the motor end plate to … WebMechanisms of fasciculation. Fasciculations have been attributed to a prejunctional depolarising action of succinylcholine, resulting in repetitive firing of the motor nerve terminals and antidromic discharges that manifest as uncoordinated muscle contractions [16, 17]. Studies have been undertaken to evaluate the prejunctional mechanism of ...

WebThe conformational mechanism of action of suxamethonium Marshall et al. [10] reported in 1990 that it takes two molecules of suxamethonium, as it takes two molecules of acetylcholine, to open one nicotinic channel. In other words, each half-molecule of suxamethonium acts like one acetylcholine, and each molecule of suxamethonium
