(contracted from N-methyl-alpha-methylphenethylamine
) is a strong central nervous system (CNS) stimulant that is mainly used as a recreational drug. Methamphetamine hydrochloride
is approved by the United States Food and Drug Administration (USFDA) under the trade name Desoxyn
for attention deficit hyperactivity disorder
and obesity in adults and children, and is sometimes prescribed off label for narcolepsy
and idiopathic hypersomnia. It is rarely prescribed due to concerns involving human neurotoxicity and its high potential for recreational use, among other concerns, and the availability of safer substitute drugs with comparable treatment efficacy.
