Inhalational amyl nitrite is available in generic form.
Amyl nitrite is a rapidly acting vasodilator administered by inhalation which is preferably used in the treatment of angina and cyanide poisoning. It is a clear, yellowish liquid having a peculiar ethereal, fruity odor.
It is volatile, even at low temperatures, and is flammable. Indeed, it works solely by relaxing smooth muscles of blood vessels (capacitance vessels) resulting in increased blood and oxygen supply to the heart by reducing its workload.
However, amyl nitrite is also used for other conditions including congestive cardiac failure and acute ischemic syndrome or myocardial infarction as determined by your doctor.
This drug has been used by some people to improve sex or to cause an intense rush, euphoria, and a sensation of excitement but such uses in this way are not recommended. Besides, amyl nitrite is responsible for some unwanted adverse effects if too much is inhaled.
In general, this medicine is known as 'poppers' and it is often used for certain non-medical purposes because of illegal availability on the street.
