The term "amyl nitrite" encompasses several isomers.In older literature, the common non-systematic name amyl was often used for the pentyl group, where the amyl group is a linear or normal (n) alkyl group, and the resulting amyl nitrite would have the structural formula CH 3 (CH 2) 3 CH 2 ONO, also referred to as n-amyl nitrite.
Brunton's clinical use of amyl nitrite to treat angina was inspired by earlier work with the same reagent by Arthur Gamgee and Benjamin Ward Richardson. Brunton reasoned that the pain and discomfort of angina could be reduced by administering amyl nitrite to open the coronary arteries of patients. In 1874, Brunton was made a Fellow of the Royal ...
A nitrovasodilator is a pharmaceutical agent that causes vasodilation (widening of blood vessels) by donation of nitric oxide (NO), [1] and is mostly used for the treatment and prevention of angina pectoris. This group of drugs includes nitrates (esters of nitric acid), which are reduced to NO in the body, as well as some other substances.
Another frequently encountered nitrite is amyl nitrite (3-methylbutyl nitrite). Alkyl nitrites were initially, and largely still are, used as medications and chemical reagents, a practice which began in the late 19th century. In their use as medicine, they are often inhaled for relief of angina and other heart
Amyl nitrites were part of some kits used to treat cyanide poisoning, containing amyl nitrite, sodium nitrite, and sodium thiosulfate. The nitrites were administered to produce methemoglobin and induce vasodilation. [40] [41] Amyl nitrites were discontinued in 2012 in standard cyanide kits. [42] Cyanide kits now use hydroxocobalamin. [43]
In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [1] It is a powerful vasodilator with a half-life of a few seconds in the blood. Standard pharmaceuticals such as nitroglycerine and amyl nitrite are precursors to nitric oxide.

In 1863, he made known the peculiar properties of amyl nitrite, a drug which was largely used in the treatment of breast-pang (angina pectoris), and he introduced the bromides of quinine, iron and strychnia, ozonized ether, styptic and iodized colloid, peroxide of hydrogen, and ethylate of soda, substances which were soon largely used by the ...
