title: Verapamil has no effect on porto-hepatic pressure gradient, hepatic blood flow and elimination function of the liver in patients with liver cirrhosis.
abstract: This study aimed to assess the effects of verapamil, a calcium-channel blocker, on porto-hepatic pressure gradient and on hepatic function as measured by the intrinsic hepatic clearance of indocyanine green (ICG) in patients with biopsy proven alcoholic cirrhosis. Hepatic venous pressures and hepatic extraction of ICG were measured before and 60 min after intravenous injection of 10 mg of verapamil in 19 consecutive patients. Hepatic blood flow and intrinsic hepatic clearance of ICG were calculated in the 10 patients whose hepatic extraction fraction was higher than 10%. No significant difference was observed when comparing porto-hepatic pressure gradient (17.72 +/- 4.79 vs. 17.77 +/- 4.43 mmHg), hepatic blood flow (13.47 +/- 4.75 vs. 16.13 +/- 7.88 ml.min-1.kg-1) and intrinsic hepatic clearance of ICG (1.99 +/- 0.54 vs. 1.97 +/- 0.45 ml.min-1.kg-1) before and after verapamil injection. We conclude that verapamil has no beneficial effect in patients with alcoholic cirrhosis.
