Question: what is the difference between prevacid and omeprazole?
Answer: Prilosec (omeprazole) and Prevacid (lansoprazole) are proton pump inhibitors (PPIs) used for the treatment of conditions such as ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome, which are all caused by stomach acid. Prevacid is also used to treat erosive esophagitis.
