Ranitidine, also known by the brand name Zantac, is a histamine H 2 -receptor antagonist, also known as an H 2 -blocker, and an Antiulcer Agent. Ranitidine is used to treat certain ulcers and prevent their return. They are also used to treat some conditions, like Zollinger-Ellison disease, in which the stomach produces too much acid. They work by decreasing the amount of acid produced by the stomach.
