Ranitidine is used to reduce acidity in the stomach. It acts by
Ablocking the histamine H2 receptors in the stomach wall so that less acid is released
Bneutralising the acid already present with a base
Ckilling bacteria in the gut
Dblocking the histamine H1 receptors involved in allergy
Answer: A
Ranitidine (like cimetidine) is an H2-receptor antagonist. It prevents histamine from stimulating the stomach wall to release acid. It does not neutralise acid chemically.
