Brallobarbital was abarbiturate developed in the 1920s.[1] It hassedative andhypnotic properties, and was used for the treatment ofinsomnia. Brallobarbital was primarily sold as part of a combination product calledVesparax, composed of 150 mgsecobarbital, 50 mg brallobarbital and 50 mghydroxyzine.[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. Vesparax reportedly was the drug that musician Jimi Hendrix supposedly overdosed on and led to his untimely death. It is no longer made.[4]
