Rapacuronium
Rapacuronium is a rapid-onset, short-acting non-depolarizing aminosteroid neuromuscular blocking agent that competitively antagonizes acetylcholine at the nicotinic receptor at the neuromuscular junction, producing rapid neuromuscular blockade suitable for tracheal intubation. It was withdrawn from clinical use due to a significantly higher than expected incidence of severe bronchospasm, particularly in patients with asthma.
