Candocuronium is bisquaternary aza steroid derivative with neuromuscular blocking, ganglion blocking, and vagolytic activities. Its potential adjunctive use in anesthesia to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation was briefly evaluated in clinical studies in India, but further development discontinued because of attendant cardiovascular effects, primarily tachycardia that was no worse than but also not an improvement over the clinically established pancuronium bromide.
