Butallylonal is a barbiturate derivative invented in the 1920s.[1] It has sedative properties, and was used primarily as an anaesthetic in veterinary medicine.[2] Butallylonal is considered similar in effects to pentobarbital but is longer in action, being considered an intermediate-acting barbiturate rather than short-acting.
