Rocuronium (Zemuron, Esmeron) is an aminosteroid non-depolarizing neuromuscular blocker or muscle relaxant used in modern anaesthesia, to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation. Suxamethonium chloride is better than rocuronium in making it easy to intubate. ==Development== It was designed to be a weaker antagonist at the neuromuscular junction than pancuronium; hence its monoquaternary structure and its having an allyl group and a pyrrolidine group attached to the D ring quaternary nitrogen atom. Rocuronium has rapid onset, and intermediate duration of action. It was introduced in 1994, and is marketed under the trade name of Zemuron in the United States and Esmeron in most other countries. There is considered to be a risk of allergic reaction to the drug in some patients (particularly those with asthma), but a similar incidence of allergic reactions has been observed by using other members of the same drug class (non-depolarizing neuromuscular blocking drugs). The γ-cyclodextrin derivative sugammadex (trade name Bridion) has been recently introduced as a novel agent to reverse the action of rocuronium. Sugammadex has been in use since 2009 in many European countries, however it has been turned down for approval twice by the US FDA and is currently unavailable for use in the US due to concerns over allergic reactions and bleeding. On July 27, 2012, the U.S. state of Virginia replaced pancuronium bromide, one of the three drugs used in execution by lethal injection, with rocuronium. It is colloquially referred to as "the rock." == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Rocuronium bromide」の詳細全文を読む スポンサード リンク
