Dexlansoprazole is Effective in Relieving Heartburn during the Fasting Month of Ramadan.

BACKGROUND AND AIMS: Proton pump inhibitors are effective at reducing heartburn. No studies have evaluated their efficacy in Ramadan. Dexlansoprazole has a unique active formulation independent of time-of-day dosing or food. The aim is to investigate the efficacy of dexlansoprazole 60 mg during Ramadan in patients with symptomatic heartburn.

METHODS

Subjects recruited using poster, radio, and SMS advertisements completed a diary using a mobile-friendly application and received daily SMS reminders. Dexlansoprazole was started on day 8 for 3 weeks. No placebo arm was used in this trial. Primary endpoint was relief of heartburn expressed as mean 24-h free heartburn percentage (24FH%) per weekly period.

RESULTS

A total of 32 patients were enrolled. During week 1, only 1 person (3.1%) was heartburn-free and mean 24FH% was 41.1 ± 24.8%. On dexlansoprazole, mean 24FH% rose to 63.4 ± 23.8 and 81.6 ± 24.5% in weeks 2 and 4, respectively (p < 0.001 for both). Median 24FH% increased from 35.7% in week 1 to 71.4 and 85.7% in weeks 2 and 4, respectively. Mean Gastroesophageal Reflux Disease Questionnaire (GERDQ) scores decreased from 10.0 ± 3.2 in week 1 to 6.53 ± 2.2 in week 2 (p < 0.001) and 5.87 ± 2.1 in week 4 (p < 0.001). Mean heartburn severity score decreased from 2.5 ± 1.0 to 1.7 ± 0.8 (p = 0.001). Early response was higher in patients with GERDQ scores ≥8 (p = 0.012).

CONCLUSION

Dexlansoprazole is effective in the treatment of heartburn during Ramadan. Clinicaltrials.gov number: NCT03079050.
