説明

Rocuronium bromide is a short-acting nondepolarizing steroidal neuromuscular blocker introduced in the U.S.A as Zemuron and in the United Kingdom as Esmeron. k is indicated for use as an adjunct to general anesthesia to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation. Rocuroniurn bromide has a significantly more rapid onset than other intermediate acting neuromuscular blockers, comparable to succinylcholine but with a very stable cardiovascular profile and has an improved side effect profile. It has been reported that good to excellent intubation conditions were achieved only one minute after a bolus dose of 600μg/kg of rocuronium bromide. It has a short duration of action, therefore, is useful for rapid sequence intubation without unacceptable delays in the spontaneous recovery of neuromuscular function.

定義

ChEBI: Rocuronium bromide is the organic bromide salt of a 5alpha androstane compound having 3alpha-hydroxy-, 17beta-acetoxy-, 2beta-morpholino- and 16beta-N-allyllyrrolidinium substituents. It has a role as a neuromuscular agent and a muscle relaxant. It is an organic bromide salt and a quaternary ammonium salt. It contains a rocuronium. It derives from a hydride of a 5alpha-androstane.

生物学の機能

Rocuronium bromide (Zemuron) is a recently approved amino steroid neuromuscular blocking agent. It has a rapid onset of action (1 minute), but its duration of action is intermediate (55 minutes), about that of vecuronium. On rare occasions, it may release histamine and cause cardiac irregularities. Rapacuronium bromide (Raplon) is the most recent neuromuscular blocking agent approved by the United States Food and Drug Administration (FDA). It is an analogue of vecuronium and is thus categorized as an amino steroid. It has a rapid onset of action (1.5 minutes) and a short to intermediate duration of action (20 minutes).This makes it a suitable alternative to mivacurium or succinylcholine for short procedures. It is eliminated mainly by the liver.Adverse effects are dose dependent; they include tachycardia, hypotension, and bronchospasm. These effects may be related to the ability of the drug to release a small amount of histamine.
