ACIPHEX (rabeprazole sodium)

Gastrointestinal Approved 1999-08-19

Aciphex helps patients manage various acid-related conditions of the stomach and esophagus, including gastroesophageal reflux disease (GERD) and duodenal ulcers. In adults, it is used to heal esophageal damage, maintain that healing, and provide relief from symptoms like daytime and nighttime heartburn. It also treats pathological hypersecretory conditions such as Zollinger-Ellison Syndrome and is used in combination with specific antibiotics to eliminate H. pylori bacteria. Adolescents aged 12 and older may also use it for short-term relief of GERD symptoms.

How ACIPHEX Works

Aciphex works by inhibiting the H+, K+ ATPase enzyme, commonly known as the proton pump, found on the secretory surface of gastric parietal cells. Once the drug is converted into its active form within these cells, it blocks the final step of gastric acid secretion. This process effectively suppresses the amount of acid the stomach produces to allow for tissue healing and symptom relief.
