Vedclass · Answer

(B) Sodium hydrogencarbonate,magnesium hydroxide,or aluminium hydroxide are simple antacids that neutralize the excess acid in the stomach but do not control the underlying cause of acid production.Cimetidine and ranitidine are better antacids because they act as histamine receptor antagonists.They prevent the interaction of histamine with the receptors present in the stomach wall,which results in the release of a lesser amount of acid,thereby providing a more effective and long-lasting solution to hyperacidity.
