HOW DO VASODILATORS WORK?
Vasodilators are drugs used for relaxing the muscles of the blood vessels to treat severe conditions.
Vasodilators may either act directly on the arteries or veins to relax them or act via different mechanisms to produce dilation. Severe hypertension or angina is caused due to increased resistance of blood flow in the blood vessels. Thus, vasodilators dilate the blood vessels to increase blood flow and relieve pressure.
