  • Title: [Pathophysiological and pharmacotherapeutic aspects of portal hypertension].
    Author: Sieber CC, Stalder GA.
    Journal: Schweiz Med Wochenschr; 1993 Jan 13; 123(1-2):3-13. PubMed ID: 8093646.
    Abstract:
    Pharmacological prophylaxis and the therapy of complications of portal hypertension have recently been attracting more attention. This especially holds true for gastroesophageal variceal bleeding. Vasoconstrictors such as vasopressin, somatostatin, and beta-blockers, as well as vasodilators such as organic nitrates, alpha 2-adrenergic agonists and serotonin-antagonists, are currently used in clinical settings. The aim of this article is to delineate the present pathophysiological concepts accounting for the hemodynamic changes in animal models and patients with portal hypertension, and to summarize the mechanisms of action of the most frequently used pharmacological agents.
