A double-blind, randomized comparison of omeprazole Multiple Unit Pellet System (MUPS) 20 mg, lansoprazole 30 mg and pantoprazole 40 mg in symptomatic reflux oesophagitis followed by 3 months of omeprazole MUPS maintenance treatment: a Dutch multicentre trial.
BACKGROUND
Proton pump inhibitors (PPIs) have proved to be effective in treating reflux oesophagitis. Until now, no study had compared the PPIs omeprazole Multiple Unit Pellet System (MUPS), lansoprazole and pantoprazole in patients with reflux oesophagitis.


OBJECTIVE
To compare omeprazole MUPS 20 mg, lansoprazole 30 mg and pantoprazole 40 mg for treatment effect in symptomatic reflux oesophagitis.


METHODS
Patients with grade I-IV symptomatic reflux oesophagitis were randomized to double-blind omeprazole 20 mg once morning, lansoprazole 30 mg o.m. or pantoprazole 40 mg o.m. Patient satisfaction and symptoms were evaluated after 4 and 8 weeks. Patients not satisfied after 8 weeks were treated for another 4 weeks with omeprazole 40 mg MUPS (open). Successful treatment was followed by 3 months' maintenance treatment with omeprazole MUPS 20 mg (patients satisfied after 4 or 8 weeks) or omeprazole MUPS 40 mg (patients satisfied after 12 weeks).


RESULTS
On intention-to-treat (ITT) analysis (n = 461) at 4 and 8 weeks, respectively, 84% and 87% (omeprazole MUPS), 78% and 81% (lansoprazole), and 84% and 89% (pantoprazole) were free of heartburn. Equivalence was found between omeprazole MUPS and pantoprazole (heartburn relief), but not with lansoprazole. Patient satisfaction after 4 and 8 weeks, respectively, was 79% and 89% (omeprazole MUPS), 76% and 86% (lansoprazole), and 79% and 91% (pantoprazole). Patient satisfaction was similar in all treatment groups. During maintenance, 87% in the omeprazole MUPS 20 mg group and 81% in the omeprazole MUPS 40 mg group were satisfied after 3 months.


CONCLUSIONS
Omeprazole MUPS 20 mg and pantoprazole 40 mg have equivalent efficacy in the treatment of reflux oesophagitis. Based on patient satisfaction, omeprazole MUPS 20 mg, lansoprazole 30 mg and pantoprazole 40 mg are equally effective.
