Health - addiction - illegal drugs - amyl nitrite - The chemical compound amyl nitrite (here referring to isoamyl nitrite) is an alkyl nitrite. It has a characteristic penetrating odour, and produces marked effects on the human body when its vapour is inhaled. It acts as a vasodilator (expanding blood vessels and thus lowering blood pressure) and finds applications in medicine in the treatment of heart disease such as angina. Amyl nitrite is also used to treat cyanide poisoning. It induces the formation methemoglobin which binds cyanide into non-toxic cyanomethemoglobin. When used recreationally, doses of it are often called poppers. See alkyl nitrites for more information on its recreational use as an inhalant. The effects of amyl nitrite are thought to be due to the action of nitric oxide in the body.- 固opFoto
