Vasopressors: Types, Purpose and Side Effects - Cleveland Clinic
2022年6月10日 · What is a vasopressor? A vasopressor is a drug that healthcare providers use to make blood vessels constrict or become narrow in people with low blood pressure. Often, these are people in shock who are unable to get enough blood to their vital organs. Without oxygen-rich blood, your organs can’t function, which can be fatal.
Use of vasopressors and inotropes - UpToDate
2023年12月8日 · Vasopressors are a powerful class of drugs that induce vasoconstriction and thereby elevate mean arterial pressure (MAP). Vasopressors differ from inotropes, which increase cardiac contractility; however, many drugs have both vasopressor and inotropic effects.
List of Vasopressors - Drugs.com
Vasopressors are medicines that constrict (narrow) blood vessels, increasing blood pressure. They are used in the treatment of extremely low blood pressure, especially in critically ill patients.

2020年2月20日 · Milrinone inhibits intracellular adenylyl cyclase, thereby increasing intracellular cyclic AMP levels. Primary effect is positive inotropy, with positive chronotropy as well. Secondary effect is peripheral vasodilation. Cardiac output is increased due …
Vasopressors — ICU One Pager
Shock comes in many flavors and so do vasopressors. Here’s a #OnePager summarizing my approach to pressors including when to start, which ones to use, how to administer them, and when to increase or wean. Includes my favorite pedagogical device for vasopressor: the pressor-speedometer from beta to alpha adrenergic effects..
Antihypotensive - Wikipedia
An antihypotensive, also known as vasopressor, is an agent that raises blood pressure by constricting blood vessels, thereby increasing systemic vascular resistance. This is different from inotropes which increase the force of cardiac contraction. Some substances do both (e.g. dopamine, dobutamine).

2008年9月2日 · Inotropic and vasopressor agents have increasingly become a therapeutic cornerstone for the management of several important cardiovascular syndromes.
Pressors 101 – Sinai EM
2022年10月23日 · Pressors, by and large, attempt to improve blood pressure by altering the cardiac output and/or the systemic vascular resistance (BP = CO x SVR). Be aware, however, that perfusion is not as straightforward as a simple math problem.
Medical Definition of Pressor - RxList
A pressor substance is any substance that elevates arterial blood pressure. For example, prostacyclin (also known as prostaglandin PGI2) is a potent pressor agent. The word "pressor" comes from the French verb "presser" meaning "to exert pressure" or "to squeeze."

Exciting to vasomotor activity; producing increased blood pressure; denoting afferent nerve fibers that, when stimulated, excite vasoconstrictors, which increase peripheral resistance.
