  • Title: [Complicated ulcer; prevention and therapy of upper gastrointestinal bleeding; indications for antacid therapy].
    Author: Holtermüller KH.
    Journal: Z Gastroenterol; 1980 Jun; 18(6):297-301. PubMed ID: 7415351.
    Abstract:
    Antacids reduce gastric acidity by neutralization, diminish peptic activity by increasing luminal pH above that optimal for proteolysis and provide thereby the rational for their use in ulcer disease. In clinical trials antacids fastened ulcer healing in patients with duodenal ulcer but not with gastric ulcer when compared to placebo. Furthermore, the prophylactic use of antacid medication can significantly reduce the frequency of acute bleeding when gastric content is titrated to a pH greater 3.5 on an hourly basis. Cimetidine does not adequately protect seriously ill patients from acute upper gastrointestinal tract bleeding. Antacids are better for this purpose. So far the efficacy of an antacid therapy has not been proven in controlled trials in patients with chronic ulcer disease, in patients with recurring ulcers following gastric surgery and in patients bleeding from acute or chronic gastroduodenal lesions.
