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 antacids were tested and by the age and sex of the patient. The preparations also differed considerably in acid-neutralizing capacity and ability to bind bile salts, as well as cost. We conclude that individuals requiring antacid therapy should be allowed to chose from among a range of preparations, in order to maximize compliance.
