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 Indications

Aciphex

Aciphex treats erosive and symptomatic GERD, duodenal ulcers, and hypersecretory conditions like Zollinger-Ellison syndrome. It is approved for adults and adolescents 12 and older, but not for children under 12.

  • Healing of erosive or ulcerative GERD

  • Maintenance of GERD healing

  • Symptomatic GERD in adults and adolescents 12+

Pantoprazole

Pantoprazole treats erosive esophagitis caused by GERD and hypersecretory conditions like Zollinger-Ellison syndrome. It is approved for adults and children as young as 5, but is not meant for immediate heartburn relief.

  • Short-term treatment of erosive esophagitis from GERD

  • Maintenance of healing of erosive esophagitis

  • Zollinger-Ellison syndrome and other hypersecretory conditions

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.

Pros

  • Simple once-daily 20 mg dose covers most GERD indications

  • FDA-approved for symptomatic GERD in adolescents 12 and older

  • Specifically labeled for doses up to 100 mg/day in Zollinger-Ellison syndrome

Cons

  • Only available as an oral tablet, no liquid or IV option

  • Not approved for GERD treatment in children under 12

  • Typical monthly list price runs $658 to $1,536, far higher than pantoprazole

Pantoprazole

Pantoprazole's availability in tablet, suspension, and IV forms makes it adaptable for patients who cannot take oral pills, including young children. Its GI side effects like diarrhea and nausea are reported more often than Aciphex's, and it is not indicated for quick heartburn relief.

Pros

  • Available as tablet, oral suspension, or IV injection for flexible dosing

  • FDA-approved for use in children as young as 5 years old

  • Typical monthly list price is $10 to $170, far lower than Aciphex

Cons
