Apronal

Apronal (brand name Sedormid), or apronalide, also known as allylisopropylacetylurea or allylisopropylacetylcarbamide, is a hypnotic/sedative drug of the ureide (acylurea) group synthesized in 1926[1] by Hoffmann-La Roche that is no longer used except in Japan (See Japanese article). Though it is not a barbiturate, apronalide is similar in structure to the barbiturates (being an open-chain carbamide instead of having a heterocyclic ring).[2] In accordance, it is similar in action to the barbiturates, although considerably milder in comparison (formerly used as a daytime sedative at doses of 1 to 2 grams every 3 to 4 hours).[2] Upon the finding that it caused patients to develop thrombocytopenic purpura, apronalide was withdrawn from clinical use.[3]
