What does an h2 blocker do? |

H2 blockers are a group of medicines that reduce the amount of acid produced by the cells in the lining of the stomach. They are also called 'histamine H2-receptor antagonists' but are commonly called H2 blockers. They include cimetidine, famotidine, nizatidine and ranitidine, and have various different brand names.

Regarding this, what is the difference between a proton pump inhibitor and an h2 blocker?
