Aminorex, sold under the brand names Menocil and Apiquel among others, is a weight loss (anorectic) stimulant drug.^[2]^[3] It was withdrawn from the market after it was found to cause pulmonary hypertension (PPH).^[3]^[4] In the United States, aminorex is a Schedule I controlled substance.

Aminorex, in the 2-amino-5-aryloxazoline group, was developed by McNeil Laboratories in 1962.^[5] It is closely related to 4-methylaminorex (4-MAR). Aminorex has been shown to have locomotor-stimulant effects, lying midway between dextroamphetamine and methamphetamine. Aminorex effects have been attributed to the release of catecholamines.^[6] It can be produced as a metabolite of the deworming medication levamisole, which is sometimes used as a cutting agent of illicitly produced cocaine.^[7]^[8]
