Serious Side Effects Of Vasodilators

A vasodilator is a type of medication that dilates or opens up blood vessels. Vasodilators work through a mechanism that causes changes in the muscles inside of the venous and arterial walls. This mechanism allows an individual's blood to flow more effortless through the blood vessels so the heart does not have to work so hard. There are three types of this medication: venous dilators, arterial dilators, and mixed dilators. Vasodilators are prescribed to individuals who have high blood pressure, pulmonary hypertension, preeclampsia, angina, or heart failure that require treatment. Vasodilators are not the preferred or first method of treating these diseases and conditions because they are known to be very potent. Vasodilators are used in cases where a patient's condition or disease is not able to be controlled through other means.
