Abstract

Drug therapy plays a major role in the management of any cardiac disease. Cardiac drugs encompass a large number of prescription medications that are used to control heart disease. It includes a complicated group of drugs with many being used for multiple heart condition. This chapter covers the cardiac glycosides, vasodilators, adrenergic blocking agents, calcium channel blockers, antidysrhythmia medication, anticoagulants, inotropic medications, angiotensin-converting enzyme, diuretics, adrenergic agonists, and cholesterol-lowering medications. Cardiac glycosides are a class of medications used to treat failing heart. It augments the strength and speed of myocardial contractions. It inhibits sodium-potassium pump and increase intracellular calcium, which causes an effective contraction to heart muscles and produce a positive inotropic effect. Vasodilators as the name implies, this drugs relax the smooth muscles in blood vessels, which causes the vessels to dilate. Antidysrhythmia drugs are used to treat abnormal heart rhythm resulting from irregular electrical activity of the heart.
