aprobarbital

Also known as Alurate, Allypropymal, 5-Isopropyl-5-allylbarbituric acid, 5-Allyl-5-isopropylbarbituric acid, 5-(1-Methylethyl)-5-(2-propenyl)-2,4,6(1H,3H,5H)-pyrimidinetrione, 5-Allyl-5-isopropylpyrimidine-2,4,6(1H,3H,5H)-trione

Aprobarbital (or aprobarbitone), sold under the brand names Oramon, Somnifaine, and Allonal, is a barbiturate derivative invented in the 1920s by Ernst Preiswerk. It has sedative, hypnotic, and anticonvulsant properties, and was used primarily for the treatment of insomnia. Aprobarbital was never as widely used as more common barbiturate derivatives such as phenobarbital and is now rarely prescribed. It has been largely replaced by newer drugs with a better safety margin.
