Losartan, the first ARB. Angiotensin II receptor blockers (ARBs), formally angiotensin II receptor type 1 (AT 1) antagonists, [1] also known as angiotensin receptor blockers, [2] [3] angiotensin II receptor antagonists, or AT 1 receptor antagonists, are a group of pharmaceuticals that bind to and inhibit the angiotensin II receptor type 1 (AT 1) and thereby block the arteriolar contraction and ...
Other serious side effects may include kidney problems, low blood pressure, and angioedema. [8] Use in pregnancy may harm the baby and use when breastfeeding is not recommended. [9] It is an angiotensin II receptor antagonist and works by blocking the effects of angiotensin II. [8] Valsartan was patented in 1990, and came into medical use in ...
All of the physiological effects of angiotensin II, including the release of aldosterone, are antagonized in the presence of losartan. Reduction in blood pressure occurs independently of the status of the renin–angiotensin system. As a result of losartan dosing, plasma renin activity increases due to the removal of the angiotensin II feedback.
Angiotensin-2 receptor blockers (ARBs). These drugs also help your blood vessels relax and open up. ... They can also walk you through the potential side effects and what you can expect.
[5] [9] Serious side effects may include kidney problems, low blood pressure, and angioedema. [5] Use in pregnancy may harm the baby and use when breastfeeding is not recommended. [10] It is an angiotensin II receptor antagonist and works by blocking the effects of angiotensin II. [5] Irbesartan was patented in 1990, and approved for medical ...
Telmisartan is the only ARB that can cross the blood–brain barrier and can therefore inhibit centrally mediated effects of Ang II, contributing to even better blood pressure control. [1] All of the ARBs have the same mechanism of action and differences in their potency can be related to their different pharmacokinetic profiles.
Angioedema, one of the rare side effects of ACEI and ARB. Some side effects of ACEI include hypotension, renal insufficiency, and hyperkalemia. [7] Dry cough is also a common side effect believed to be associated with decreased bradykinin breakdown. Angioedema is another possible but rare complication due to elevated levels of bradykinin.

The choice between the drugs is to a large degree determined by the characteristics of the patient being prescribed for, the drugs' side effects, and cost. Most drugs have other uses; sometimes the presence of other symptoms can warrant the use of one particular antihypertensive.
