Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	AChR
In vitro	Rocuronium bromide (RB), an aminosteroid type neuromuscular blocking agent, acts by reducing or inhibiting the depolarising effect of acetylcholine on the terminal disc of the muscle cell. Rocuronium interacts with human liver microsomal cytochromes P450 (CYP) by binding to the substrate site. Rocuronium has caused inhibition of both reactions by 20 and 15%, respectively.
In vivo	Rocuronium is an ideal muscle relaxant with a rapid onset, intermediate duration of action, nondepolarizing properties and lack of cardiovascular side effects. Rocuronium produces a dose-dependent duration of neuromuscular blockade in isoflurane anesthetized horses. Rocuronium bromide, is a relatively low potency, intermediate-acting agent with a rapid onset time of 98 seconds in dogs. Rocuronium is an effective nondepolarizing muscle relaxant in the cat under the clinical conditions of this study. Rocuronium has a rapid onset, a short duration of action. Rocuronium (0.6 mg/kg) results in a significant increase in heart rate one min after IV administration in the dog. Rocuronium (0.3 mg/kg and 0.6 mg/kg) produce a reliable neuromuscular block of 23–32 min duration, respectively. Rocuronium bromide paralyzes the internal laryngeal muscles keeping the vocal cords in an intermediate position (paramedial) 60 seconds after being administered in cats.
