naloxone

n. nonaddictive synthetic drug used to treat effects of drug overdose and detect a drug addiction (Pharmacology)

Naloxone is a drug used to counter the effects of opioid overdose, for example heroin or morphine overdose. Naloxone is specifically used to counteract life-threatening depression of the central nervous system and respiratory system. It is marketed under various trademarks including Narcan, Nalone, and Narcanti, and has sometimes been mistakenly called "naltrexate." It is not to be confused with Naltrexone, another opioid receptor antagonist with qualitatively different effects, used for dependence treatment rather than emergency overdose treatment.
