GtoPdb Ligand ID: 4004

Synonyms: Quelicin® | suxamethonium
succinylcholine is an approved drug (FDA (1952))
Compound class: Synthetic organic
Comment: Succinylcholine (sux) is a short-acting depolarizing neuromuscular blocker. It acts as an acetylcholine agonist at nicotinic acetylcholine receptors at neuromuscular junctions, resulting in persistent depolarization of the motor end plate.

Summary of Clinical Use
Skeletal muscle relaxant used in surgical procedures where a rapid onset and brief duration of muscle relaxation is required.
Mechanism Of Action and Pharmacodynamic Effects
Succinylcholine mimics the effects of acetylcholine but without being rapidly hydrolysed by acetylcholinesterase, leading to persistent depolarisation of the neuromuscular junction leading to desensitisation.
