Drugs for Angina Treatment

Angina pectoris
Angina pectoris is a painful cardiac condition that occurs when the work load on the heart and the onsequent oxygen demand of the myocardium exceed the ability of the cardiovascular system to meet that demand. The pain may vary from a relatively mild ache to a crushing chest pain which may radiate to the left shoulder and left arm and other areas. It is often triggered off by exertion, and usually subsides rapidly with rest. It is basically a stress response to factors that increase cardiac demand and output, and is often linked with an atheromatous narrowing of the coronary arteries.
Treatment of angina is with coronary vasodilator drugs that reduce cardiac drive and lower the myocardial oxygen demand (many of which are also used in the treatment of hypertension. They include the time-honoured glyceryl trinitrate (which can be given by several routes), other nitrates, calcium channel blocking agents, beta-adrenergic receptor blocking agents and potassium channel activators. Glyceryl trinitrate is of particular value when a rapid response is required. The following Table gives an indication of the wide range of anti-anginal products currently available.
