Frequently asked questions

What does Aciphex treat?
Aciphex (Rabeprazole Sodium) may be used to treat duodenal ulcer, gastroesophageal reflux, heartburn, zollinger-ellison syndrome, helicobacter infections, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Aciphex work?
Aciphex is a proton pump inhibitor. Proton pump inhibitors block the H+/K+ ATPase 'proton pump' in the stomach's acid-making cells, the final step in producing stomach acid. By binding this pump, they sharply and lastingly cut acid output, easing heartburn and helping ulcers heal.
