Lansoprazole, sold under the brand name Prevacid among others, is a medication which reduces stomach acid.[4] It is a proton pump inhibitor (PPI), used to treat peptic ulcer disease, gastroesophageal reflux disease, and Zollinger–Ellison syndrome.[5] Its effectiveness is similar to that of other PPIs.[6] It is taken by mouth.[4] Onset is over a few hours and effects last up to a couple of days.[4]

Common side effects include constipation, abdominal pain, and nausea.[4][3] Serious side effects may include osteoporosis, low blood magnesium, Clostridium difficile infection, and pneumonia.[4][3] Use in pregnancy and breastfeeding is of unclear safety.[1] It works by blocking H+/K+-ATPase in the parietal cells of the stomach.[4]

Lansoprazole was patented in 1984 and came into medical use in 1992.[7] It is available as a generic medication.[5] In 2021, it was the 216th most commonly prescribed medication in the United States, with more than 1 million prescriptions.[8][9]
