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[2] or as an anticonvulsant to counteract side effects from other anaesthetics.

[3] It is the thiobarbiturate analogue of secobarbital.
