In a double-blind trial 60% of acute variceal bleeding episodes were controlled with terlipressin (glypressin) compared with 37% in patients given placebo (NS). Rebleeding was more common in the placebo group so that at 5 days bleeding remained under control in 54% of patients treated with terlipressin compared with only 19% after placebo therapy (p less than 0.025). Blood transfusion requirements were similar in the two groups. Terlipressin appeared to be the most effective in those patients with severe hepatic dysfunction.
