A steroid-based neuromuscular blocker reversing agent; selectively reverses rocuronium-induced neuromuscular blockade over that induced by mivacurium or atracurium in anesthetized rhesus monkeys; prevents formation of postoperative peritoneal adhesions in rats; increases the total number of neurons in the hippocampus compared to control and improves motor coordination in a beam walking test in a rat model of ischemia-reperfusion injury (16 and 100 mg/kg)
