Efficacy of Benzodiazepines to Laryngopharyngeal Reflux: A Double-Blind, Randomized Controlled Study / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Anti-anxiety drugs such as benzodiazepines are often given to globus patients in practice, based on the notion that globus is a kind of somatization disorder. However, many of globus are caused by laryngopharyngeal reflux (LPR) and the effects of anti-anxiety drugs to LPR are unknown. The study goal was to assess the efficacy of benzodiazepines to LPR. SUBJECTS AND METHOD: We selected 51 LPR patients, who were confirmed by 24-hour double-probe ambulatory pH monitoring. Patients were allocated into case and control groups at random and entered into a double-blind trial. Patients in the control group received proton pump inhibitors and prokinetics. Diazepam was added to patients in the case group. Assessments were made after 4 weeks of treatment using reflux symptom index (RSI) and reflux finding score (RFS). RESULTS: In both groups, RSI and RFS were improved significantly at the end of the study. However, there was no significant difference between the two groups. CONCLUSION: Diazepam seems to have little efficacy in the treatment of LPR.
