Brallobarbital is a barbiturate developed in the 1920s.[1] 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.[2] The long half-life of this combination of drugs tended to cause a hangover effect the next day,[3] and Vesparax fell into disuse once newer drugs with lesser side effects had been developed.[4]
