Aciphex vs. Pantoprazole
See how Aciphex and Pantoprazole compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Both Aciphex and Pantoprazole are proton pump inhibitors that reduce stomach acid to treat GERD, but Aciphex covers symptomatic GERD in adolescents 12+ while Pantoprazole is approved down to age 5.
Aciphex is only available as an oral tablet, while Pantoprazole also comes as an oral suspension and IV injection for people who cannot swallow pills.
Pantoprazole's typical list price is much lower than Aciphex's, though both carry similar long-term risks such as bone fracture and C. difficile infection.
Aciphex vs. Pantoprazole Drug Summary
Aciphex
Aciphex (rabeprazole) is a proton pump inhibitor that lowers stomach acid to treat GERD, duodenal ulcers, and rare acid-overproduction conditions like Zollinger-Ellison syndrome. It comes as a delayed-release tablet taken once daily for most uses, with higher doses split twice daily for hypersecretory conditions.
Pantoprazole
Pantoprazole is a proton pump inhibitor that lowers stomach acid to heal erosive esophagitis from GERD and manage hypersecretory conditions like Zollinger-Ellison syndrome. It comes as a tablet, oral suspension, or IV injection, usually taken once or twice daily depending on the condition.

Aciphex vs. Pantoprazole Pros and Cons
Aciphex
Aciphex offers a simple once-daily tablet for most GERD indications, with escalating doses reserved for rare hypersecretory conditions. It is one of the few PPIs specifically labeled for use in adolescents with symptomatic GERD, but it comes at a steep price compared to generic alternatives.

Not approved for GERD treatment in children under 12
Typical monthly list price runs $658 to $1,536, far higher than pantoprazole
Pantoprazole
