Anzic SA, et al. - An inquiry was initiated with regard to the consequence of 8 weeks of omeprazole 20 mg for laryngopharyngeal reflux (LPR) and comorbid chronic rhinosinusitis (CRS). The yielded data exhibited the efficacy of this therapy in reducing the signs and symptoms of both LPR and CRS, although in most patients it appeared to persist at the end of the trial.
