Which among the following is an antacid ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Zantac
Antacids reduce the excess acid in the stomach. Ranitidine (Zantac) stops histamine from acting on the receptors of the stomach wall, so less acid is released. It is therefore an antacid.
