Treats and prevents angina pectoris (chest pain) by improving blood flow to the heart muscle. May also be used in certain cardiac conditions where coronary blood flow needs to be improved.
Contains nitroglycerin, which converts to nitric oxide in the body. This relaxes vascular smooth muscle, causing vasodilation primarily in veins (reducing preload) and also in coronary arteries, thereby decreasing myocardial oxygen demand and increasing oxygen supply.
May cause headache, dizziness, or flushing. Contraindicated with PDE-5 inhibitors. Do not take with alcohol. Keep away from heat and open flames. If angina pain persists after 3 doses in 15 minutes, seek emergency medical attention. Store at room temperature away from moisture.
