Abstract

The circadian variation in some biologic functions may have clinical, fiscal and therapeutic implications. The authors discuss circadian variation in portal pressure in cirrhotic patients and nocturnal occurrence of bleeding from varices in these patients. The pathogenesis of the diurnal variation in portal pressure is presented. The authors submit the hypothesis that an optimal dosing regimen for non-selective beta blocker therapy in the prevention of variceal bleed must include an evening dose of beta blocker medication. In studies reporting comparative efficacy of beta blocker therapy with other modalities in the prevention of variceal bleeding, the optimal dosing schedule for beta blocker therapy must be emphasized.
