SUMMARY

Pharmacokinetic variables of etomidate were determined after iv administration of etomidate (3.0 mg/kg of body weight). Blood samples were collected for 6 hours. Disposition of this carboxylated imidazole best conformed to a 2- (n = 2) and a 3- compartment (n = 4) open pharmacokinetic model. The pharmacokinetic values were calculated for the overall best-fitted model, characterized as a mixed 2- and 3-compartmental model. The first and most rapid distribution half-life was 0.05 hour and a second distribution half-life was 0.35 hour. Elimination half-life was 2.89 hours, apparent volume of distribution was 11.87 ± 4.64 L/kg, apparent volume of distribution at steady state was 4.88 ± 2.25 L/kg, apparent volume of the central compartment was 1.17 ± 0.70 L/kg, and total clearance was 2.47 ± 0.78 L/kg/h.
