Preference for On-Demand Fexuprazan Therapy in Gastroesophageal Reflux Disease: A Prospective Cohort Study
Abstract
Introduction: Maintenance therapy is crucial in managing and preventing symptom relapse in gastroesophageal reflux disease (GERD), with continuous and on-demand therapy being the common approaches. However, maintenance therapy using potassium-competitive acid blockers (P-CABs), such as fexuprazan, remains incompletely evaluated. Methods: This single-center, single-arm, prospective cohort study enrolled individuals with weekly heartburn or acid regurgitation and confirmed erosive esophagitis. The participants received 40 mg fexuprazan daily for 4 weeks as initial therapy, followed by 4 weeks of maintenance therapy. Patients chose either continuous or on-demand therapy for maintenance, according to their preference. The primary endpoint was the proportion of patients selecting on-demand therapy. The symptom scores were assessed using the GERD questionnaire (GERD-Q) and patient assessment of upper-gastrointestinal-disorders symptoms questionnaire (PAGI-SYM). Results: The 31 included participants showed a significant reduction in symptom scores after initial treatment (baseline vs. 4-week: GERD-Q, 9.0 vs. 6.5, p < 0.001; PAGI-SYM, 29.0 vs. 10.8, p < 0.001). Twenty-one (67.7%) patients chose on-demand therapy after initial treatment. The symptom scores did not differ significantly before and after maintenance therapy (4-week vs. 8-week: GERD-Q, 6.5 vs. 6.0, p = 0.225; PAGI-SYM, 10.8 vs. 9.0, p = 0.354). Although this relation was not significant, patients experiencing larger…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 31 participants or records.
