 NYesY (what is this?)  

Nitroglycerin, also known as glyceryl trinitrate (GTN) is a medication used for heart failure, high blood pressure, and to treat and prevent chest pain from not enough blood flow to the heart. This includes chest pain due to cocaine and from a heart attack. It is taken by mouth, under the tongue, applied to the skin, and by injection into a vein.

Common side effects include headache and low blood pressure. The low blood pressure can be severe. It is unclear if use in pregnancy is safe for the baby. It should not be used together with medications within the sildenafil family. Nitroglycerin is in the nitrate family of medications. While it is not entirely clear how it works, it is believed to function by dilating blood vessels.

Nitroglycerin was written about as early as 1846 and came into medical use in 1878. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world for the pills that go under the tongue is about 0.06 to 0.22 USD per dose. It is the same substance as the chemical nitroglycerin used for explosives.

Nitroglycerin is used for the treatment of angina,acute myocardial infarction, severe hypertension, and acute coronary artery spasms.
