Acid Neutralizing Velocity of Antacids

Investigation of Acid-Neutralizing Property of Bacillus cereus GUF8

Extreme pHs, especially acidic pHs, are among the environmental stresses that some bacteria face. The most important strategies that bacteria employ for acid adaptation include either production of acidophilic proteins, or raising the pH of the microenvironment by secretion of basic compounds including ammonia produced by the action of urease. Considering the importance of acid-neutralizing bac...

Dietary citric acid enhances absorption of aluminum in antacids.

Ten healthy men ingested, twice daily between meals, during each of the seven-day experimental periods: (a) citric acid (as lemon juice), (b) Al(OH)3, or (c) Al(OH)3 + citric acid. Whole blood sampled after each dietary period was analyzed electrothermally after digestion with nitric acid. Moderate, but significant, increases in mean Al concentrations as compared with pretreatment values [5 (SD...

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...
