Answer

Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) reduce intraglomerular pressure by inhibiting angiotensin II ̶ mediated efferent arteriolar vasoconstriction. [38] These drugs also have a proteinuria-reducing effect that is independent of their antihypertensive effect.

In addition, ACE inhibitors have renoprotective properties, which may be partially due to the other hemodynamic and nonhemodynamic effects of these drugs. ACE inhibitors reduce the breakdown of bradykinin (an efferent arteriolar vasodilator); restore the size and charge selectivity to the glomerular cell wall; and reduce the production of cytokines, such as transforming growth factor–beta (TGF-beta), that promote glomerulosclerosis and fibrosis.
