Mechanism of action of suxamethonium

WebJul 11, 2024 · Mechanism of Action Cisatracurium, like the other NMBDs, binds to the nicotinic cholinergic receptor at the muscle motor end-plate but is not capable of inducing the conformational change necessary for ion channel opening. Because acetylcholine cannot bind to its receptors, no end-plate potential can develop. WebThe plasma concentration of suxamethonium was adequately represented by a single compartment model. The mean half-life of elimination was 47 s with a 95% confidence interval of 24 to 70 s; that of effect compartment equilibration, 211 s with a 95% confidence range of 139 to 282 s. The average slope exponent was 6.4 and its 95% confidence range ...
