Common card · No. 373425

Rabeprazole, sold under the brand name Aciphex, among others, is a medication that decreases stomach acid. It is used to treat peptic ulcer disease, gastroesophageal reflux disease, and excess stomach acid production such as in Zollinger–Ellison syndrome. It may also be used in combination with other medications to treat Helicobacter pylori. Effectiveness is similar to other proton pump inhibitors (PPIs). It is taken by mouth. Common side effects include constipation, feeling weak, and throat inflammation. Serious side effects may include osteoporosis, low blood magnesium, Clostridioides difficile infection, and pneumonia. Use in pregnancy and breastfeeding is of unclear safety. It works by blocking H+/K+-ATPase in the parietal cells of the stomach. Rabeprazole was patented in 1986, and approved for medical use in 1997. It is available as a generic medication. In 2017, it was the 288th most commonly prescribed medication in the United States, with more than 1 million prescriptions.
