Gaviscon® Advance alone versus co-prescription of Gaviscon® Advance and proton pump inhibitors in the treatment of laryngopharyngeal reflux

Abstract

Objectives

Management of laryngopharyngeal reflux (LPR) typically comprises alginates and proton pump inhibitors (PPIs) alone or in combination, yet evidence to support any particular treatment regimen is lacking. We sought to evaluate the efficacy of Gaviscon® Advance alone versus co-prescription with a PPI in treating LPR.

Methods

One hundred consecutive LPR patients with a reflux symptom index (RSI) score > 10 attending our joint voice clinic (JVC) were studied prospectively. All were treated with Gaviscon® Advance four times daily. If patients had been started on a PPI prior to their JVC attendance, this was optimised to a twice-daily dosing regimen and continued. RSI scores were recorded at first attendance and 3 months post-treatment via postal questionnaire. Scores were analysed using t tests and Levene's test for equality of variances.

Results

Follow-up RSI scores were returned by 72 patients, 39 of whom were treated with Gaviscon® Advance only (group A) and 33 with Gaviscon® Advance + PPI (group B). Mean pre-treatment RSI scores were similar between groups [group A: 19.2, 95% confidence interval (CI) ± 2.4; group B: 21.3, 95% CI ± 3.2 (p = 0.65)]. No significant differences were observed with respect to 3-month post-treatment RSI scores [group A: 9.9, 95% CI ± 2.8; group B: 12.6, 95% CI ± 4.2 (p = 0.82)] and change in RSI scores [group A: 9.3, 95% CI ± 3.0; group B: 8.7, 95% CI ± 2.9 [p = 0.75]).

Conclusions

Gaviscon® Advance alone is effective in treating symptoms of LPR, while co-prescription with a high-dose PPI offers no additional benefit.
