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.
Renin comes one level higher than ACE in the renin–angiotensin system. Renin inhibitors can therefore effectively reduce hypertension. Aliskiren (developed by Novartis) is a renin inhibitor which has been approved by the U.S. FDA for the treatment of hypertension.
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.
[11] [12] [13] ACE inhibitors improve symptoms, decrease mortality and reduce ventricular hypertrophy. Angiotensin II receptor antagonist therapy (also referred to as AT 1 -antagonists or angiotensin receptor blockers), particularly using candesartan , is an acceptable alternative if the patient is unable to tolerate ACEI therapy.

Lisinopril is an ACE inhibitor, meaning it blocks the actions of angiotensin-converting enzyme (ACE) in the renin–angiotensin–aldosterone system (RAAS), preventing angiotensin I from being converted to angiotensin II. Angiotensin II is a potent direct vasoconstrictor and a stimulator of aldosterone release.
It is a combination of lisinopril, an ACE inhibitor,with amlodipine, a calcium channel blocker. [1] It may be used when blood pressure is not well controlled with each of the two agents alone. [4] It is taken by mouth. [1] Side effects may include low blood pressure, kidney problems, liver problems, cough, and high blood potassium. [4]
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.
