Thiamylal (Surital) is a barbiturate derivative invented in the 1950s. It has sedative, anticonvulsant, and hypnotic effects, and is used as a strong but short acting sedative. Thiamylal is still in current use, primarily for induction in surgical anaesthesia[1] or as an anticonvulsant to counteract side effects from other anaesthetics.[2] It is the thiobarbiturate analogue of secobarbital.
