Indications & Uses
Premacid is indicated for:
Pharmacology
Aluminium Hydroxide and Magnesium Hydroxide together form a well-balanced, non-systemic antacid combination valued for both its effectiveness and its pleasant taste. This is a dependable antacid preparation that does not cause acid rebound, constipation, or a laxative (cathartic) effect. It provides symptomatic relief from hyperacidity, including heartburn, acid indigestion, and sour stomach.
Aluminium hydroxide gel acts as a slow-acting antacid with a strong, long-lasting neutralizing capacity, and it also works as an adsorbent. Magnesium hydroxide, meanwhile, offers a slower but more sustained acid-neutralizing effect. Both the tablet and suspension forms have adsorbent properties, allowing them to form a protective coating over an ulcer surface. This coating supports healing and shields the sensitive lining of the stomach and duodenum from further irritation.
