What Pantoprazole does

Pantoprazole is a PPI similar in efficacy to omeprazole but with fewer drug-drug interactions because it has less CYP2C19 inhibition. It's often preferred in hospitalized patients and in those on clopidogrel.

What the evidence says for Black patients

Same class concerns as omeprazole. The main prescribing point relevant to Black patients is that pantoprazole has less CYP2C19 inhibition than omeprazole, so pantoprazole is often preferred when a patient is on clopidogrel. Given that Black patients carry a somewhat higher proportion of CYP2C19 loss-of-function alleles, this choice is modestly more favorable.

Long-term PPI risks apply. Same deprescribing rationale.

Common alternatives

Omeprazole, esomeprazole, rabeprazole, lansoprazole — all PPIs. H2-blockers.

Side effects

  • Same profile as omeprazole — see that page

Factors that affect adherence

Take 30 minutes before breakfast. Generic pantoprazole is inexpensive. Reassess need at least annually.

  • Do I still need this?
  • If I'm on clopidogrel, is pantoprazole the right choice compared to omeprazole?
  • What's the plan for trying to come off?
