WebWhen given intravenously, etomidate is thus a potent suppressor of adrenal steroid synthesis, lowering cortisol levels in patients for 72 hours after one injection. In the early 1980s, etomidate began to be used as a replacement for benzodiazepine-type sedatives in intensive care units. Etomidate suppresses corticosteroid synthesis in the adrenal cortex by reversibly inhibiting 11β-hydroxylase, an enzyme important in adrenal steroid production; it leads to primary adrenal suppression. Using a continuous etomidate infusion for sedation of critically ill trauma patients in intensive care units has been associated with increased mortality due to adrenal suppression. Continuous intravenous administration of etomidate leads to adrenocortical dysfunction. The mo…
