Rocuronium, sold under a number of brands, is a medication used to paralyze muscles for endotracheal intubation, including rapid sequence induction (RSI). It may also be used to relax muscles during surgery and when people are on a ventilator. It is given by injection into a vein. A single dose begins working after about 45 to 120 seconds and lasts for 25 to 90 minutes.
Common side effects include low blood pressure and high blood pressure. Other serious side effects may include anaphylaxis and prolonged muscle weakness. While not well studied in pregnancy, no harms have been found. Breastfeeding shortly following use is likely okay. Rocuronium is a neuromuscular blocker of the non-depolarizing type.
Rocuronium was approved for medical use in the United States in 1994. It is avaliable as a generic medication. In the United States it costs about 40 USD for 500 mg as of 2020. In the United Kingdom this amount costs the NHS about 25 pounds. Rocuronium is stable at room temperature for about 12 weeks.
Rocuronium is used to paralyze muscles for endotracheal intubation, including rapid sequence induction (RSI).
It should only be used with appropriate sedation.
The typical dose for rapid sequence intubation is 1.2 mg per kg. Repeat doses of 0.6 mg per kg may be used. An infusion of 10 to 12 micrograms per kg per min may also be used.
In those who are obese doses should be based on ideal body weight rather than actual body weight.
The dosage does not need to be changed in those with kidney problems. Though lower doses may be required in those with liver problems with prolonged use. Larger doses may be needed in people with large area burn and those with liver problems.
It is an aminosteroid non-depolarizing neuromuscular blocker.
Mechanism of action
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.
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 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 was turned down for approval twice by the US FDA due to concerns over allergic reactions and bleeding, but finally approved the medication for use during surgical procedures in the United States on December 15, 2015. 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 low cost compared with sugammadex.
It was introduced in 1994, and is marketed under the trade name of Zemuron in the United States and Esmeron in most other countries.
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 bromide.
On 3 October 2016, the U.S. state of Ohio announced that it would resume executions on January 12, 2017, using a combination of midazolam, rocuronium bromide, and potassium chloride. Prior to this, the last execution in Ohio was in January 2014.
On August 24, 2017, the U.S. state of Florida executed Mark James Asay using a combination of etomidate, rocuronium bromide, and potassium acetate.
