Abstract Objectives. Carvedilol is a non-selective β-blocker with intrinsic anti-α(1)-adrenergic activity, potentially more effective than propranolol in reducing hepatic venous pressure gradient (HVPG). We compared the long-term effect of carvedilol and propranolol on HVPG and assessed whether the acute response to oral propranolol predicted the long-term HVPG response on either drug. Material and methods. HVPG was measured in 38 patients with cirrhosis and HVPG ≥ 12 mm Hg at baseline and then again 90 min after an oral dose of 80 mg propranolol. Patients were double-blinded randomized to either carvedilol (21 patients) or propranolol (17 patients) and after 90 days of treatment HVPG measurements were repeated. Results. HVPG decreased by 19.3 ± 16.1% (p < 0.01) and by 12.5 ± 16.7% (p < 0.01) in the carvedilol and propranolol groups, respectively, with no significant difference between treatment regimens (p = 0.21). Although insignificant, an acute decrease in HVPG of ≥12% was the best cut-off value to predict long-term HVPG response to propranolol when using ROC curve analysis. Conclusions. This randomized study showed that carvedilol is at least as effective as propranolol on HVPG after long-term administration. Furthermore, a predictive value of an acute propranolol test on HVPG could not be confirmed.

To compare the efficacy and safety of Carvedilol and Propranolol in patients with cirrhosis-related esophagogastric varices after multiple endoscopic treatments for secondary prophylaxis.
Background: Both endoscopic variceal ligation (EVL) and propranolol are valuable methods for secondary prophylaxis of variceal bleeding. Addition of ISMN to propranolol improves the effica...

Dilated blood vessels in the ESOPHAGUS or GASTRIC FUNDUS that shunt blood from the portal circulation (PORTAL SYSTEM) to the systemic venous circulation. Often they are observed in individuals with portal hypertension (HYPERTENSION, PORTAL).
A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.
Abnormal increase of resistance to blood flow within the hepatic PORTAL SYSTEM, frequently seen in LIVER CIRRHOSIS and conditions with obstruction of the PORTAL VEIN.
A syndrome characterized by the clinical triad of advanced chronic liver disease, pulmonary vascular dilatations, and reduced arterial oxygenation (HYPOXEMIA) in the absence of intrinsic cardiopulmonary disease. This syndrome is common in the patients with LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL).
Functional KIDNEY FAILURE in patients with liver disease, usually LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL), and in the absence of intrinsic renal disease or kidney abnormality. It is characterized by intense renal vasculature constriction, reduced renal blood flow, OLIGURIA, and sodium retention.
