Description |
A potent vasodilator which decreases preload by increasing venous capacity, pooling venous blood pressure in the peripheral veins, reducing ventricular filling pressure and decreasing arterial BP. Because of this cascade it also causes vasodilation in coronary arteries that are in spasm and may assist in the redistribution of blood flow along the collateral channels in the heart |
