Are antacids cytoprotective?

Proton pump inhibitors are not antacids!

Proton pump inhibitors (PPIs) are among the most commonly prescribed drugs in clinical practice. Since the introduction of these potent acid-suppressing agents in the late 80s, they were listed in the Guinness Book of World Records as the most prescribed in human history. Yet, to be effective in inhibiting the proton pump enzyme (H+/K+ ATPase) in the parietal cells, these drugs should be taken ...

Antipeptic activity of antacids.

An in vitro experiment based on the digestion of haemoglobin with pepsin was carried out to test the claim made by some manufacturers that the antacids used in their proprietary preparations had an intrinsic antipeptic activity independent of the change brought about by alteration of pH. In no case could these claims be substantiated.

Comparative study of commercial antacids

Comparative study of four antacids.

Four antacid preparations have been studied in a stratified, randomized, double-blind trial to evaluate criteria which determine patients' acceptance of this type of therapy. There was a considerable range of judgements about palatability, but preference was determined not only by factors such as the smell, taste, texture and after-taste of the preparation, but also by the order in which the an...

Antacids and peptic ulcer--a reappraisal.

Antacids can reduce gastroduodenal acidity for long periods if taken in substantial quantities after food. Their healing effect on gastric ulcer is minimal, if present at all, and easily overwhelmed by the benefit obtained from admission to hospital. Intensive antacid therapy appears effective in healing duodenal ulcer and preventing haemorrhage from stress ulcer, and is comparable in these res...
