Nitroglycerin (commonly called just nitro) is a vasodilator, meaning it’s a medicine that opens blood vessels to improve blood flow. It is used to treat angina pectoris symptoms, such as pressure or chest pain that occurs when there is not enough blood flowing to the heart.
To improve the blood flow, Nitro opens up the coronary arteries (arteries in the heart), which improves symptoms, reduces pain, and reduces how hard the heart has to work.
Nitroglycerin comes in long-acting and quick-acting forms. Quick-acting forms are used to relieve angina pectoris or before activities that often cause troubles with angina. The quick-acting forms are tablets or oral sprays. The tablets are placed under the tongue or between the cheek and gum. The spray is most commonly used under the tongue, but it can be sprayed on the tongue too.
If you suffer from heart issues, please keep nitroglycerin near, it saved many lives before and it could save your life too.
