- Protein binding
Variable. Plasma protein binding of rapacuronium was studied in vitro for human plasma by equilibrium dialysis. The protein binding was variable and ranged between 50% and 88%, which was at least partly due to hydrolysis of rapacuronium bromide to its 3-hydroxy metabolite. The specific plasma protein to which rapacuronium binds is unknown. Plasma protein binding of the 3-hydroxy metabolite was not determined.
- Metabolism
Hydrolyzed to active metabolites (Cytochrome P450 system is not involved).
