What are the different types of antianginal drugs?
different types of antianginal drugs most often include nitroglycerin, beta-blockers and calcium channel blockers. Antianginal drugs are used to treat angina pectoris , a medical term for chest pain. These drugs can be used separately, in combination or together with other medicines.
Angina pectoris , often simply called "angina", causes discomfort in the chest, which can be felt like pressure, tightness, pressing or feeling of difficulty. The pain can radiate the neck, jaws, back, arms and teeth. Angina pectoris is caused by a reduced supply of oxygen in the blood to a part of the heart, which is often the result of narrow or clogged arteries. Other symptoms may include digestion, nausea, sweating and convulsions.

Beta-blockers are usually used in combination with other types of antianginal drugs and usually only after other medicines do not work.
