Brallobarbital (Vesparax) is a barbiturate derivative invented in 1964. It has sedative and hypnotic properties, and was used for the treatment of insomnia. Brallobarbital was primarily sold as part of a combination product called Vesparax, composed of 150 mg secobarbital, 50 mg brallobarbital and 50 mg hydroxyzine.[1] The long half-life of this combination of drugs tended to cause a hangover effect the next day,[2] and Vesparax fell into disuse once newer drugs with less side effects had been developed.[3]
