Intravenous therapy with high doses of ranitidine and omeprazole in critically ill patients with bleeding peptic ulcerations of the upper intestinal tract: an open randomized controlled trial.

Thirty-nine critically ill patients with actively bleeding peptic ulcerations--Forrest Ib--in the stomach or duodenum were randomly allocated to intravenous therapy with 400 mg ranitidine per day or 80 mg omeprazole per day (120 mg on the 1st day) for 5 days. Successful therapy was proven by control endoscopy on day 6 if less than 2.5 liters of blood had to be transfused from the start of therapy to maintain a hemoglobin value of 10g/l or above. Treatment failure meant that more than 2.5 liters of blood were necessary to maintain a hemoglobin level above 10 g/l. Of 20 patients in the ranitidine group bleeding stopped in only 3 patients (15%). Of 17 patients who continued bleeding under ranitidine therapy the bleeding could be controlled in 13 patients after changing to omeprazole treatment. Of 19 patients in the omeprazole group bleeding stopped in 16 patients (84%). These results demonstrate that the significantly more effective reduction of acidity by omeprazole is promising for the therapy of bleeding peptic ulcerations and may reduce the need for invasive therapy or operation.
