What is the advantage of using antihistamines over antacids in the treatment of acidity ?

Explanation

Usual antacids control only the symptoms and not the cause They work by neutralising the acid produced in the stomach but do not control the cause of production of more HCI Antihistamines, on the other hand, are drugs which suppress the action of histamine responsible for secretion of pepsin and HCI in the stomach. In other words. antihistamines prevent the binding of histamine with the receptors present in the stomach wall. As a result, less HCI is produced and hyperacidity is cured Thus, a better treatment for curing acidity is to use antihistamines over antacids
