Atracurium is a medication classified as a non-depolarising neuromuscular blocking agent. It is used in anaesthesia to induce muscle relaxation. Atracurium works by blocking the action of acetylcholine at the neuromuscular junction, preventing the transmission of nerve impulses to muscle cells.

Suxamethonium is a medication classified as a neuromuscular blocking agent or a depolarising muscle relaxant. It acts by mimicking the neurotransmitter acetylcholine at the neuromuscular junction. It initially depolarises the muscle membrane, causing a brief muscle contraction, and then it prevents repolarisation due to constant depolarization that results in desensitisation, resulting in sustained muscle relaxation.

A 55-year-old obese female patient presents with a life-threatening asthma attack and develops acute respiratory failure. She requires the insertion of an endotracheal tube. She is going to be given a muscle relaxant to aid with the insertion of the endotracheal tube.

Which muscle relaxant is a depolarising blocker?
a
