Rocuronium (Zemuron, Esmeron) is an aminosteroid non-depolarizing  neuromuscular blocker or muscle relaxant used in modern anaesthesia to facilitate endotracheal intubation by providing skeletal muscle relaxation, most commonly required for surgery or mechanical ventilation. It is used for both standard and rapid sequence induction  (RSI), although Suxamethonium chloride is usually selected for RSI given its shorter duration of action compared to rocuronium.
