Sugammadex is a novel neuromuscular blocking reversal agent. Its mechanism of action is the encapsulation of rocuronium and vecuronium molecules. Numerous studies show a potential role of magnesium in reducing anesthetic requirements, sympathetic response to surgical trauma, antinociceptive action and neuroprotective effects. However, its use is limited because magnesium potentiates non-depolarizing neuromuscular blocking agents.
