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 endotracheal intubation and rapid sequence induction (RSI), although Suxamethonium chloride is usually selected for RSI given its faster onset of action compared to rocuronium.[1]
Pharmacology[edit]
Mechanism of action[edit]
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 a rapid onset and intermediate duration of action.[2] 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).[3]
The γ-cyclodextrin derivative sugammadex (trade name Bridion) has been recently introduced as a novel agent to reverse the action of rocuronium.[4] Sugammadex has been in use since 2009 in many European countries; however, it was turned down for approval twice by the US FDA due to concerns over allergic reactions and bleeding,[5] but finally approved the medication for use during surgical proceedures in the United States on December 15, 2015.[6] Neostigmine can also be used as a reversal agent of rocuronium but is not as effective as sugammadex. Neostigmine is often still used due to its lower cost compared to sugammadex.[7]
Society and Culture[edit]
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.[citation needed]
On 3rd October, 2016, the U.S. state of Ohio announced that it would resume executions on January 12, 2017, using a combination of of midazolam, rocuronium bromide, and potassium chloride. Prior to this, the last execution in Ohio was in January 2014.[8]
