Question: is zantac a proton pump inhibitor?
Answer: Zantac (ranitidine) and Prilosec (omeprazole) are two brand name medications that can treat gastroesophageal reflux disease (GERD). Zantac works as a histamine H2 antagonist and Prilosec works as a proton pump inhibitor. Although they both work differently, they produce similar effects such as reduced stomach acid.
