Etomidate, an ultrashort-acting non-barbiturate sedative derived from imidazole, exerts potent inhibitory effects on the central nervous system. It is commonly employed for the induction of intravenous general anaesthesia or assisted anaesthesia. Recently, etomidate has emerged as an alternative to narcotics and novel psychoactive substances, leading to an increasing trend of abuse.

From chemical point of view these compounds belong to structurally diverse categories, such as barbiturates - thiopental (Sodium pentothal®, Trapanal®, Pentothal®), methohexital (Brevital®), and hexobarbital (Evipan®, Hexenal®, Citopan®, Tobinal®); non-barbiturate derivatives - ketamine (Ketalar® Ketaset®), esketamine (Ketanest®), and etomidate (Amidate®, Hypnomidate®), phenolic derivatives - propofol (Diprivan®); steroid derivatives - mixture of alfadolone and alfaxalone (Althesin® in human and Saffan® in veterinary anesthesia); and derivatives of phenylacetic acid - propanidid (Epontol®, Sombrevin®). Most of these compounds are chiral, with the exception of propofol and propanidid.

Introduction: Complex spikes (CSs) activity of cerebellar Purkinje cells plays critical roles in motor coordination and motor learning by transferring information to cerebellar cortex, which is an accessible and useful model for neurophysiological investigation. Etomidate is an ultrashort-acting nonbarbiturate intravenous anesthetic, which inhibits the spontaneous activity of cerebellar Purkinje cells through activation of GABAA and glycine receptors in vivo in mice. However, the effect of etomidate on the spontaneous CSs activity of cerebellar Purkinje cells in living mouse is not clear.
