Dexamyl
（重定向自Drinamyl）
Dexamyl (or Drinamyl in the UK) is the brand name of a combination drug composed of amobarbital (previously called amylbarbitone) and dextroamphetamine.
First introduced in 1950 by Smith, Kline and French, Dexamyl was marketed as an antidepressant medication that did not cause agitation, and also as an anti-anxiety drug and diet drug. Amphetamine alone had previously been marketed as an antidepressant (under the Benzedrine Sulfate brand) beginning around 1938. The amphetamine in Dexamyl was intended to elevate mood, while the barbiturate was added to counter the side effects of the amphetamine. Its name is a portmanteau of dextroamphetamine and amylbarbitone.
