H2-receptor antagonists and antacids in the prevention of acute gastrointestinal haemorrhage in fulminant hepatic failure. Two controlled trials.


In two controlled trials, involving 75 patients, on the prevention of bleeding from gastric erosions in fulminant hepatic failure, antacids given four-hourly had no significant effect. Only 35% of intragastric pH recordings taken at two-hourly intervals in the treated group were maintained above 5 with the doses used, whereas this could be consistently achieved with the histamine H2-receptor antagonists, metiamide and cimetidine. In the group receiving these drugs only 1 patient out of 26 bled, compared with 13 (54%) of the controls, a highly significant difference. Blood-transfusion requirements were significantly less in those treated with H2-receptor antagonists.
