Succinylcholine Chloride

Succinylcholine is a short-acting depolarizing neuromuscular blocking agent approved by the FDA for co-administration with sedatives or hypnotics. By blocking acetylcholine, succinylcholine disrupts cholinergic receptors in the parasympathetic and sympathetic nervous systems, leading to skeletal muscle relaxation. This mechanism facilitates rapid endotracheal intubation, surgical procedures, and mechanical ventilation. Off-label use includes adjunctive therapy during electroconvulsive therapy to control electrically induced muscle contractions. This activity reviews succinylcholine’s indications, mechanism of action, pharmacokinetics, contraindications, and adverse effects. Administration strategies, monitoring parameters, drug interactions, and clinical toxicology are discussed to enhance understanding of safe and effective use. Emphasis is placed on optimizing patient outcomes through appropriate dosing and risk mitigation. The role of the interprofessional healthcare team in managing succinylcholine therapy is highlighted, ensuring coordinated and evidence-based patient care.
