    Abstract:
    Beta-adrenoceptor blockers used in the medical management of portal hypertension decrease liver blood flow. The sporadic onset of hepatic encephalopathy during propranolol treatment was ascribed to this decrease. The aim of the present study was to evaluate the effect of chronic treatment with nadolol on liver blood flow and liver function. Nadolol, a non-cardioselective beta-adrenoceptor blocker, has been reported to be as powerful as propranolol in decreasing portal pressure. Before and after 1 month of treatment with nadolol at a dose reducing heart rate by 25%, in 15 cirrhotic patients with portal hypertension, the following parameters were determined: hepatic venous pressure gradient, hepatic blood flow, galactose eliminating capacity, aminopyrine metabolic activity, ICG clearance and intrinsic hepatic clearance. Hepatic venous pressure gradient and hepatic blood flow were decreased by nadolol. However liver function was not affected by the drug. We conclude that, despite a lowered hepatic blood flow, liver function is not affected by 1 month of nadolol treatment.
