Correct Answer - D
Our stomach produces hydrochloric acid, which helps in the digestion of food without harming the stomach. During indigestion the stomach produces, too much acid and this causes pain and irritation. To get rid of the pain, people use base called antacids.
Antacids. which neutralise the excess acit treat only the symptomes but not the cause. Magnesium hydroxide (milk of magnesia), a mild base, is often used for this purpose. On the other hand, cimetidene and rantidne prevent the release of excess hydrochloric acid in the stomach. Earlier, cimetidne (Tegamet) was the largest selling drug in the would but these days the most widely used drug of this type is ranitidine (Zantac).
