Abstract:A pharmacokinetic study of atracurium besylate was performed in the pig after a single i.v. bolus injection of 2 mg/kg, the dose needed to produce surgical neuromuscular blockade. The plasma concentration values were obtained by high performance liquid chromatography. Using a two-compartment pharmacokinetic model, the elimination half life was found to be 28.6 +/- 6.3 min (mean +/- SEM), the total volume of distribution 341 +/- 56 ml/kg and the plasma clearance 8.7 +/- 1.1 ml/min/kg. Although the doses require… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
