Reading

Cardiovascular Drugs

Cardiovascular drugs may be divided into three groups: drugs that affect the heart; drugs that affect blood pressure; and drugs that prevent blood clotting.

Drugs that affect the heart. Drugs may affect the heart in two major ways: changing the rate and forcefulness of the heartbeat.

The most common drugs used to change the rate and forcefulness of the heartbeat are the digitalis glycosides (cardiac glycosides). These drugs are used to treat patients in heart failure (when the heart is not contracting with sufficient force). Most of the digitalis glycosides are obtained from the leaf of the digitalis (foxglove) plant. The important effects of the digitalis glycosides are the strengthening of the myocardium (heart muscle) and the slowing of the rate of the heart contraction. Examples of digitalis are digoxin, and digitoxin.

Other drugs, which belong to the general class of sympathomimetics are used to increase heart rate and the force of contraction. These include isoproterenol and epinephrine.

Drugs used to correct abnormal heart rhythm are called antiarrhythmics. Examples of these drugs are quinidine, procainamide, lido-caine and propranolol.

Drugs that affect blood pressure. Vasodilators are drugs which relax the muscles of vessel walls. Blood flows more freely and blood pressure falls as blood vessels open and become dilated. Examples of nitrite drugs are nitroglycerin and amylnitrite. Nitroglycerin dilates all smooth muscles in the body including the muscles of the coronary blood vessels. The pain (angina pectoris) caused by a lack of adequate blood flow to the heart is relieved by placing nitroglycerin under the tongue.

A third type of drugs used to lower blood pressure is called a diuretic, an agent which promotes excretion of fluid. An example of this type of drug is chlorothiazide (Diuril).

Vasoconstrictors are drugs which constrict muscle fibers around blood vessel opening. Vasoconstrictors are needed to raise blood pressure, increase the force of heart action and stop local bleeding. Examples of vasoconstrictor drugs are epinephrine (adrenaline), vasopressin and aramine (metaraminol).

Drugs that prevent blood clotting. These drugs are called anticoagulants. They are used to prevent the formation of clots in veins and arteries. Heparin is an anticoagulant chemical substance. When given intravenously, heparin prevents the formation of clots within vessels. Aspirin is the most widely used anticoagulant.
