Cardiovascular agents are drugs that affect the rate and intensity of cardiac contraction, blood vessel diameters, blood volume, blood clotting and blood cholesterol levels. [1] They are indicated to treat diseases related to the heart or the vascular system (blood vessels), such as hypertension , hyperlipidemia , coagulation disorders , heart ...
Vasoactive drug therapy is typically used when a patient has the blood pressure and heart rate monitored constantly. The dosage is typically titrated (adjusted up or down) to achieve a desired effect or range of values as determined by competent clinicians. Vasoactive drugs are typically administered using a volumetric infusion device (IV pump).
PDE3 inhibitors also have an impact on the smooth muscles found in our blood vessels. By increasing cAMP levels, these medications cause the smooth muscles to relax. [ 34 ] This relaxation has a significant benefit in our blood vessels as it leads to vasodilation , which means the blood vessels widen.
A vasoprotective is a medication which acts to alleviate or prevent conditions or diseases which affect the blood vessels.The term is used in the World Health Organization's Anatomical Therapeutic Chemical Classification System to encompass therapeutic agents used in the treatment of hemorrhoids or varicose veins.

When the blood vessels suddenly relax, it results in vasodilation. In vasodilatory shock, the blood vessels are too relaxed leading to extreme vasodilation and blood pressure drops and blood flow becomes very low. Without enough blood pressure, blood and oxygen will not be pushed to reach the body's organs.
A nitrovasodilator is a pharmaceutical agent that causes vasodilation (widening of blood vessels) by donation of nitric oxide (NO), [1] and is mostly used for the treatment and prevention of angina pectoris. This group of drugs includes nitrates (esters of nitric acid), which are reduced to NO in the body, as well as some other substances.

The narrowing of blood vessels leads to an increase in peripheral resistance, thereby elevating blood pressure. While vasoconstriction is a normal and essential regulatory mechanism for maintaining blood pressure and redistributing blood flow during various physiological processes, its dysregulation can contribute to pathological conditions.
