Antihypotensive agent. An antihypotensive agent, also known as a vasopressor agent or pressor, is any medication that tends to raise reduced blood pressure.
Pressor Drugs for Treating Hypotension. Pressor drugs are used to treat hypotension resulting from cardiogenic shock, circulatory shock (including septic), hemorrhagic shock, and hypotension that sometimes occurs during surgical anesthesia.Arterial pressure can be raised by increasing cardiac output and by constricting the systemic vasculature.Most pressor drugs are sympathomimetic agents that mimic the effects of sympathetic adrenergic activation on the heart (cardiostimulatory drugs) and blood vessels (vasoconstrictor drugs).Some of these drugs increase heart rate and cardiac contractility by stimulating cardiac beta 1 -adrenoceptors (beta-agonists).ressor Drugs for Treating Hypotension.
