Final answer:
Rocuronium is a muscle relaxant used in anesthesia, with a dosing range of 0.6 to 1.2 mg/kg and hast onset times of 1 to 2 minutes. It has an intermediate duration of 30 to 40 minutes and is metabolized primarily by the liver.
Step-by-step explanation:
Rocuronium is often considered in the context of Anesthesiology as a non-depolarizing neuromuscular blocking agent used to facilitate tracheal intubation and provide muscle relaxation during surgery or mechanical ventilation. Normal dosing for rocuronium in an adult varies, with an intubating dose typically ranging from 0.6 to 1.2 mg/kg. Rocuronium has a rapid onset of action, usually within 1 to 2 minutes after administration, and has an intermediate duration of action, lasting approximately 30 to 40 minutes. Metabolism of rocuronium is primarily hepatic, with some involvement of renal pathways, and it is excreted mostly in bile and urine.
