    Abstract:
    Terlipressin (Glypressin), a synthetic analog of vasopressin, induces arteriolar vasoconstriction which causes both a portal hypotensive effect and certain side-effects on the systemic circulation (elevated arterial pressure and reduced cardiac output). The combination of nitroglycerin with terlipressin might accentuate the portal hypotensive effect and prevent the side-effects on the systemic circulation. The aim of this study was to examine the systemic and splanchnic hemodynamic responses to terlipressin administered alone or combined with nitroglycerin in patients with cirrhosis. Systemic and splanchnic hemodynamics were measured before and 1 h after a bolus of terlipressin (1 to 2 mg IV) given alone (n = 10) or in association with nitroglycerin infusion (25 micrograms/min, n = 9). Terlipressin alone significantly increased the arterial pressure by 21%, systemic vascular resistance by 60%, and significantly decreased cardiac output by 23%. The right atrial and pulmonary pressures significantly increased and the wedged hepatic venous pressure and hepatic venous pressure gradient significantly decreased by 8% and 16%, respectively. The combined therapy decreased the cardiac output by 20%, but did not significantly modify the other systemic and splanchnic hemodynamic values. No significant differences were found between terlipressin and the combined therapy concerning changes in wedged hepatic venous pressure or hepatic venous pressure gradient. We conclude that in patients with cirrhosis, nitroglycerin prevents the deleterious vasoconstrictor and vasopressor effects of terlipressin. However, the combined therapy, as terlipressin alone, decreases the cardiac output.(ABSTRACT TRUNCATED AT 250 WORDS)
