Methaqualone is a sedative-hypnotic medication that was widely prescribed during the mid-20th century. It was marketed under various brand names, including Quaalude ( ) and Sopor, typically containing 300 mg of methaqualone per tablet. A combination drug known as Mandrax was sold primarily in Europe, containing 250 mg of methaqualone and 20 mg of diphenhydramine in a single tablet.
Methaqualone belongs to the quinazolinone class of compounds. Its commercial production was discontinued in many countries during the mid-1980s due to widespread misuse, addiction, and associated public health concerns.
