Current Primary Outcome Measures  ICMJE
 (submitted: July 17, 2012)
Post Nasal Drainage Symptom Response [ Time Frame: 8 and 16 weeks ]
The primary outcome measure was postnasal drainage symptom response measured by using a visual analogue scale. At 8 and 16 weeks, a horizontal symptoms scale from 0% (no change) to 100% (symptoms completely resolved) was presented to participants to assess improvement in postnasal drainage symptoms.

Current Secondary Outcome Measures  ICMJE
 (submitted: July 17, 2012)
  • Rhinosinusitis Outcome Measure(RSOM-31) [ Time Frame: Baseline, 8 weeks, and 16 weeks ]
    RSOM-31 includes 31 questions combined into a total score ranging from 0 to 155 with higher scores representing greater disease burden. Values are based on patient report.
  • Sino Nasal Outcome Test (SNOT-20) [ Time Frame: Baseline, 8 weeks and 16 weeks ]
    SNOT-20 includes 20 questions combined into a total score ranging from 0 to 100 with higher numbers representing greater rhinosinusitis health burden and represents patient-reported symptom severity.
  • Quality of Life Questionnaire (QOLRAD) [ Time Frame: Baseline, 8 weeks and 16 weeks ]
    The patient-reported QOLRAD consists of 25 questions combined into a total score ranging from 25 to 175 with higher numbers representing better quality of life.

Brief Title  ICMJE Efficacy of Lansoprazole in Chronic Post Nasal Drip
Official Title  ICMJE Randomized Placebo-Controlled Trial of BID Lansoprazole in Isolated Chronic Post Nasal Drip
Brief Summary The purpose of this study is to determine whether aggressive acid suppression with Lansoprazole is effective in the treatment of post nasal drip, and also assess the predictors of response based on clinical and physiologic parameters.
Detailed Description Postnasal drip (PND) is a common complaint that brings patients to the attention of their primary care physicians. It is also one of the most common reasons for patients to seek care from otolaryngologists. Traditionally, PND has been considered and treated as a symptom of sinonasal pathology. It has also been shown, along with Gastroesophageal reflux disease (GERD) and asthma, to be a major contributor to the development of chronic cough. PND refractory to treatment aimed at sinonasal disease is sometimes treated with anti-GERD therapy. This treatment modality is based on clinical experience. To date, there are no studies in the literature to support a causal relationship between PND and extraesophageal reflux (EER). In a case control study of patients with and without esophagitis El-Serag et al reported a significant association (odds ratio 1.6, 95%CI 1.4-1.8) between sinusitis and GERD. A later study by Ulualp et al in 11 CT confirmed cases of chronic sinusitis resistant to therapy with conventional sinus therapies they found a significantly higher prevalence of hypopharyngeal acid exposure in the sinusitis group than controls. Recently, in an open label prospective pilot trial, DiBaise et al treated 11 patients with sinusitis and 19 GERD patients with omeprazole 20mg bid for 3-months. 9/11 sinusitis patients were found to have GERD by pH monitoring and there was moderate (25-89%) improvement in the sinus symptoms in the omeprazole treated group. However, there are currently no placebo-controlled trials assessing efficacy of PPI's in patients with PND.
