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).
Midodrine, sold under the brand names ProAmatine and Orvaten among others, is a vasopressor or antihypotensive medication used to treat orthostatic hypotension (low blood pressure when standing) and urinary incontinence. [3] [5] [1] It is taken by mouth. [3] [1]
EMCrit is an American medical collective and publishing group made up of physicians in the field of critical care and emergency medicine. [ 1 ] [ 2 ] The group publishes a number of digital resources to equip physicians, clinical pharmacists, nurses , paramedics and researchers .
Although both vasopressors, vasopressin and epinephrine differ in that vasopressin does not have direct effects on cardiac contractility as epinephrine does. [18] Thus, vasopressin is theorized to be of increased benefit over epinephrine in cardiac arrest due to its properties of not increasing myocardial and cerebral oxygen demands. [18]

Vasopressin (antidiuretic hormone, ADH) is another vasopressor often used in combination with norepinephrine [10] Certain vasopressors ( ephedrine , norepinephrine ). Norepinephrine (Levophed) is the most common first-line vasopressor for people who don't respond well to other hypotension treatments such as fluid resuscitation.
Septic shock, especially septic shock where treatment is delayed or the antimicrobial drugs are ineffective, however has a mortality rate between 30% and 80%; cardiogenic shock has a mortality rate of up to 70% to 90%, though quick treatment with vasopressors and inotropic drugs, cardiac surgery, and the use of assistive devices can lower the ...
This concept does not exclude therapy by means of i.v. fluid, inotropes or vasopressors, the only restriction is to avoid completely normalizing blood pressure in a context where blood loss may be enhanced. [2] When a person starts to bleed (big or small) the body starts a natural coagulation process that eventually stops the bleed.
