Nitroglycerin, formally 1,2,3-propanetriol trinitrate, is a venerable explosive and, in small doses, a life-saving drug. After numerous accidents, the manufacture and distribution of the pure liquid was soon banned in many jurisdictions.
Audrey: My father has a heart condition. He needs his medication. Medical Use. In pharmaceutical form, nitroglycerin sometimes called glyceryl trinitrate, probably to prevent alarming patients is used as a heart medication, which is unlike its unstable counterpart, as it cannot be rendered even slightly explosive. Angina occurs when the coronary arteries become constricted ischemia and are incapable of carrying sufficient oxygen to the heart muscle, resulting in suffocating chest pain.
Nitroglycerin is converted to nitric oxide a natural vasodilator within the body, which in turn causes the coronary artery blood vessels surrounding the heart to dilate, increasing blood flow and thereby improving the oxygen supply to the heart. As a result chest pains subside as the blood pressure decreases and the heart rate increases. Although nitroglycerin only controls chest pains, it does not cure the condition i. Also it may lose effectiveness over long periods of use.
Nitroglycerin has the following side effects as the body adjusts to the medication:. Constricted artery leads to high blood pressure and an increased heart rate. After nitroglycerin administration. A rtery dilates, improving blood flow; alleviating chest pain. Go Back to Top of Page. Nitroglycerin has the following side effects as the body adjusts to the medication: Headaches Flushing Rapid heartbeat Restlessness.
