Angiotensin II Receptor Blockers: No Role in Portal Hypertension of Cirrhosis


Despite the role angiotensin II plays in the pathogenesis of portal hypertension in patients with cirrhosis, antagonists of this enzyme are apparently of little use in prevention of the variceal bleeding it can cause. In fact, controlled studies indicate that angiotensin II receptor blockers (ARBs) produce arterial hypotension in some patients without adequately reducing portal pressure.
