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 ...
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.
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.
Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD.

Reflecting the critical role of zinc, ACE can be inhibited by metal-chelating agents. [14] ACE in complex with inhibitor lisinopril, zinc cation shown in grey, chloride anions in yellow. Based on PyMOL rendering of PDB 1o86. The picture shows that lisinopril is a competitive inhibitor, since it and angiotensin I are similar structurally.
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 ...
Use of ACE inhibitors was also associated with a reduction in pneumonia related mortality, although the results were less robust than for overall risk of pneumonia." [51] An April 2020 study of patients hospitalized in Hubei Province in China found a death rate of 3.7% for patients with hypertension who were taking ACE inhibitors or ARBs. The ...
These results also indicate that the N-domain possess a broader selectivity than the C-domain. Another difference between the older ACE inhibitors and RXP 407 is the molecular size of the compound. The older ACE inhibitors had mostly been interacting with S 1 ’, S 2 ’ and S 1 subsites but RXP 407 interacts in addition with the S 2 subsite.
