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 ...

There are many classes of antihypertensives, which lower blood pressure by different means. Among the most important and most widely used medications are thiazide diuretics, calcium channel blockers, angiotensin-converting enzyme inhibitors (ACE inhibitors), angiotensin II receptor blockers or antagonists (ARBs), and beta blockers.
Angiotensin-converting-enzyme inhibitors (ACE inhibitors) are a class of medication used primarily for the treatment of high blood pressure and heart failure. [1] [2] This class of medicine works by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart.
ARBs are blocking the last part of the renin–angiotensin pathway and block the pathway more specifically than ACE inhibitors. [1] The AT 1 receptor mediates Ang II to cause increased cardiac contractility, sodium reabsorption and vasoconstriction which all lead to increased blood pressure. By blocking AT 1 receptors, ARBs lead to lower blood ...
Angiotensin-converting enzyme (EC 3.4.15.1), or ACE, is a central component of the renin–angiotensin system (RAS), which controls blood pressure by regulating the volume of fluids in the body. It converts the hormone angiotensin I to the active vasoconstrictor angiotensin II .
An ACE inhibitor and thiazide combination is a drug combination used to treat hypertension (high blood pressure). They are given by mouth.ACE inhibitors reduce the activity of angiotensin-converting enzyme (ACE) which produces angiotensin II, a hormone that constricts blood vessels.
It was also proposed that ACE binds by hydrogen bonding to the terminal, non scissile, peptide bond of the substrate. [3] But since ACE is a dipeptide carboxypeptidase, unlike carboxypeptidase A, the distance between the cationic carboxyl-binding site and the zinc atom should be greater, by approximately the length of one amino acid residue.
