Vasopressin and its analogs are used inthe treatment of bleeding esophageal varices. Since gastrointestinal reflux may have a deleterious effect on variceal hemorrhage, the effect of 2,3-phenylalanine-8-lysine-vasopressin upon the lower esophageal sphincter (LES) was studies by rapid pull-through manometry in 24 persons. PLV infusion up to a dosis of 2.7 mU/kg/h raised LES pressure from 15.1 +/- 1.3 (SEM) to 17.9 +/- 2.0 mm Hg. Higher doses lowered LES pressure progressively to 12.1 +/- 0.7 mmHg at 54 mU/kg/h. The serum gastrin level did neither correlate with basal LES pressure not with LES pressure changes during PLV infusion. Therefore, PLV does not appear to act indirectly through serum gastrin. Because of the danger of systemic side effects and of the undesirable in LES pressure with the usual high doses of vasoactive substances, a continuous infusion of lower doses of vasopressin analogs appears to be advantageous.
