Antacids and ulcer healing. A review of the evidence

There have been a number of controlled trials of antacids in the treatment of patients with peptic ulcer disease. As a general rule the size of studies has been small and there have been difficulties ensuring adequate binding, because of the formulation and taste of the antacids. Despite these difficulties, antacids appear to be effective ulcer healing agents with efficacies resembling those of other antiulcer drugs. Definite dose relationships are unclear but high doses of buffering capacity over 200 mmol/day appear unnecessary and are associated with increasingly frequent adverse effects. Low dose maintenance treatment is effective at limiting duodenal ulcer relapse.
