Rapacuronium bromide
Rapacuronium bromide is a rapidly acting, non-depolarizing aminosteroid neuromuscular blocker formerly used in modern anaesthesia, to aid and enable endotracheal intubation, which is often necessary to assist in the controlled ventilation of unconscious patients during surgery and sometimes in intensive care. As a non-depolarizing agent it did not cause initial stimulation of muscles before weakening them.
Due to risk of fatal bronchospasm it was withdrawn from the United States market by Organon on March 27, 2001, less than 2 years after its FDA approval in 1999.
