Description: Variceal bleeding is a life-threatening complication of portal hypertension. The recommended treatment includes the early administration of a vasoactive drug. Vapreotide is a somatostatin analogue with a different receptor affinity to octreotide. It decreases portal pressure and blood flow of collateral circulation in rats with cirrhosis. The pivotal study of early administration of vapreotide in patients with cirrhosis and variceal bleeding has shown a significant improvement in bleeding control and, in the subset of patients with significant bleeding, a significant reduction in mortality. In addition, a meta-analysis of four randomized studies has shown a significant improvement in bleeding control. Vapreotide administrated via the intravenous route is simple to use, with practically no contraindications and few, usually minor, side effects.
