{Abstract}: <B>UNASSIGNED: </B>Proton pump inhibitors (PPIs) play a crucial role in managing laryngopharyngeal reflux (LPR), but the optimal dosing regimen remains unclear. We aim to compare the effectiveness of the same total PPI dose administered twice daily versus once daily in LPR patients.<BR><B>UNASSIGNED: </B>We conducted a prospective randomized controlled trial at a tertiary referral hospital, enrolling a total of 132 patients aged 19-79 with LPR. These patients were randomly assigned to receive either a 10 mg twice daily (BID) or a 20 mg once daily (QD) dose of ilaprazole for 12 weeks. The Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) were assessed at 8 weeks and 16 weeks. The primary endpoint was the RSI response, defined as a reduction of 50% or more in the total RSI score from the baseline. We also analyzed the efficacy of the dosing regimens and the impact of dosing and duration on treatment outcomes.<BR><B>UNASSIGNED: </B>The BID group did not display a higher response rate for RSI than the QD group. The changes in total RSI scores at the 8-week and 16-week visits showed no significant differences between the 2 groups. Total RFS alterations were also comparable between both groups. Each dosing regimen demonstrated significant decreases in RSI and RFS.<BR><B>UNASSIGNED: </B>Both BID and QD PPI dosing regimens improved subjective symptom scores and objective laryngoscopic findings. There was no significant difference in RSI improvement between the 2 dosing regimens, indicating that either dosing regimen could be considered a viable treatment option.
