Adrenocorticotropic hormone–stimulated plasma adrenocortical steroid concentrations following administration of vehicle (V), etomidate (E), or dimethoxy-etomidate (D-E) in rats. Intravenous doses of etomidate and dimethoxy-etomidate were 0.3 mg/kg (A–D) or 3 mg/kg (E–H). Each bar represents the mean ± S.E.M. obtained from four rat experiments. *P < 0.05.
