Pantoprazole Use During Pregnancy
Safety Profile and Recommendations
Pantoprazole can be used during pregnancy when clinically indicated, as available data from observational studies have not demonstrated an association with major malformations or other adverse pregnancy outcomes. 1
- FDA data shows no evidence of harm to the fetus in animal reproduction studies with pantoprazole during organogenesis, even at doses up to 88 times the recommended human dose in rats and 16 times in rabbits 1
- A prospective study by the European Network of Teratology Information Services found no difference in the rate of major malformations between women exposed to proton pump inhibitors (PPIs) and the control group (RR=0.55,95% CI 0.08-3.95) 1
- A population-based retrospective cohort study covering all live births in Denmark from 1996 to 2008 showed no significant increase in major birth defects with first-trimester exposure to pantoprazole 1
- A meta-analysis comparing 1,530 pregnant women exposed to PPIs in at least the first trimester with 133,410 unexposed pregnant women showed no significant increases in risk for congenital malformations (OR=1.12,95% CI 0.86-1.45) or spontaneous abortions (OR=1.29,95% CI 0.84-1.97) 1
Clinical Evidence for Pantoprazole in Pregnancy
- A multicentre prospective controlled study by the European Network of Teratology Information Services specifically evaluated pantoprazole and found that the rate of major congenital anomalies did not differ between exposed and control groups (pantoprazole 2.1% vs. controls 3.8%) 2
- The study followed 53 pregnancies exposed to pantoprazole (47 in the first trimester) and found no evidence of teratogenicity 2
Treatment Considerations
- Pantoprazole is an effective proton pump inhibitor that binds irreversibly to the proton pump, reducing gastric acid secretion with a relatively long duration of action compared to other PPIs 3
- The optimal adult oral dose for gastric acid-related disorders is pantoprazole 40 mg once daily 3
- Pantoprazole has a lower propensity to become activated in slightly acidic body compartments and has minimal potential for drug interactions, which may be advantageous during pregnancy 3, 4
Practical Recommendations
- When treating acid-related disorders during pregnancy, first attempt conservative measures such as dietary and lifestyle modifications 5
- If medication is required, pantoprazole can be considered as data suggest it is not teratogenic in humans 5
- The background risk of major birth defects in the general U.S. population is 2-4%, and the risk of miscarriage is 15-20% in clinically recognized pregnancies 1
- All pregnancies have a background risk of birth defects, loss, or other adverse outcomes regardless of medication exposure 1
