General description

Etomidate is an imidazole derivative, which functions as an nonbarbiturate hypnotic agent. It is used in speech and memory test. Etomidate regulates hemodynamic stability by preserving sympathetic outflow and autonomic reflexes. It inhibits adrenal steroidogenesis.

Biochem/physiol Actions

Etomidate is a general anesthetic; potentiates GABAA transmission. The possible neuroprotective effect of etomidate against streptozotocin-induced (STZ-induced) hyperglycaemia were investigated in the rat brain and spinal cord. Etomidate treatment demonstrated neuroprotective effect on the neuronal tissue against the diabetic oxidative damage

Etomidate is an imidazole-derived hypnotic agent preferentially used for rapid sequence induction of anaesthesia because of its favourable haemodynamic profile. However, 11β-hydroxylase inhibition causes adrenal insufficiency with potentially fatal consequences in specific populations. We review the arguments against the liberal
