Nitroglycerin (medication)

Nitroglycerin (pronounced: /ˌnaɪtroʊˈɡlɪsərɪn/), also known as glyceryl trinitrate (GTN), is a medication primarily used for the treatment of angina pectoris and heart failure. It is a potent vasodilator, expanding blood vessels and increasing blood flow.

Etymology

The term "Nitroglycerin" is derived from the Greek words "nitron" (meaning "native soda") and "glykys" (meaning "sweet"). It was first synthesized in 1847 by Italian chemist Ascanio Sobrero.

Medical Uses

Nitroglycerin is used to prevent chest pain (angina) caused by heart disease. It works by relaxing and widening blood vessels so blood can flow more easily to the heart. Nitroglycerin is also used to treat congestive heart failure, to help prevent additional heart attacks in patients with a history of these conditions, and to relieve pain caused by anal fissures and piles.
