quazepam

n. a benzodiazepine used as a hypnotic agent. It is of medium potency and is highly lipid soluble, enabling rapid penetration of the blood–brain barrier and resulting in rapid onset of effects. Because its metabolic products are eliminated slowly, quazepam may accumulate in the body, leading to unwanted daytime sedation. U.S. trade name: Doral.
