40 mg pantoprazole and 40 mg esomeprazole are equivalent in the healing of esophageal lesions and relief from gastroesophageal reflux disease-related symptoms.

BACKGROUND

Proton pump inhibitors are regarded as the most effective class of acid suppressive medication for gastroesophageal reflux disease treatment. There is considerable interest regarding the dose equivalence between various proton pump inhibitors.

GOALS

To compare the efficacy of pantoprazole and esomeprazole with regard to healing and relief from gastroesophageal reflux disease-related symptoms.

STUDY

Multicenter, randomized, double-blind study. Patients with gastroesophageal reflux disease grades B/C (Los Angeles classification) received 40 mg pantoprazole daily (n = 113) or 40 mg esomeprazole daily (n = 114). Healing (endoscopy) and relief from gastroesophageal reflux disease-related symptoms (direct questioning) were assessed at first and final visit (after 4, 6, 8, or 10 weeks of treatment).

RESULTS

Overall healing in both treatment groups was 88% of patients (intention-to-treat population), 95% (pantoprazole), and 90% (esomeprazole) (per-protocol population); statistically, this indicates "at least equivalence" between treatments. Overall relief from gastroesophageal reflux disease-related symptoms was similar for pantoprazole (55%) and esomeprazole (51%, per-protoco). No correlation between healing and symptom relief was seen. The majority of reported adverse events were assessed as "not related" to the study drug. Pantoprazole and esomeprazole have comparably good safety and tolerability.

CONCLUSION

In patients with gastroesophageal reflux disease, 40 mg pantoprazole daily and 40 mg esomeprazole daily are equally effective for healing of esophageal lesions and relieving gastroesophageal reflux disease-related symptoms.
