ANTI ANGINAL

An antianginal is a drug used in the treatment of angina pectoris, a symptom of ischaemic heart disease. So, medicinal agents used for relieving or preventing pathological conditions associated with coronary insufficiency and the related ischemic heart diseases are referred to as antianginal drugs.
Also substances that suppress adrenergic systems of the heart such as β-adrenoblockers and Ca2+ channel blockers, as well as a few older drugs such as papaverine and dipyridamole, are also used for this purpose. Nitrites and nitrates exhibit direct relaxant effects on vascular, smooth musculature, which results in general dilation of vessels.
