title: Clinical trial: lansoprazole 15 or 30 mg once daily vs. placebo for treatment of frequent nighttime heartburn in self-treating subjects.
abstract: BACKGROUND
  Frequent nighttime heartburn is common. Lansoprazole 15 mg is indicated for treatment of heartburn and other gastro-oesophageal reflux disease-related symptoms.
  
  
  OBJECTIVE
  To evaluate the efficacy and safety of lansoprazole in self-treating subjects with frequent nocturnal heartburn.
  
  
  METHODS
  A total of 864 subjects with heartburn on >or=2 days/week over the past month were randomized to double-blind treatment with lansoprazole 15 or 30 mg or placebo each morning. Endpoints were percentage of night times without heartburn (primary), percentage of 24-h days without heartburn and percentage of subjects without heartburn on day 1.
  
  
  RESULTS
  Mean percentage of night times without heartburn was significantly greater with lansoprazole 15 mg (61.3%) or lansoprazole 30 mg (61.7%) vs. placebo (47.8%) over 14 days (P < 0.0001 vs. placebo for both doses). Percentage of 24-h days without heartburn and percentage of subjects without heartburn on day 1 were significantly greater with lansoprazole 15 or 30 mg vs. placebo.
  
  
  CONCLUSIONS
  Both lansoprazole 15 and 30 mg were highly effective and well tolerated in reducing symptoms in subjects with frequent nighttime heartburn. The benefit of therapy on 24-h heartburn and nighttime heartburn on day 1 of treatment was also evident. Lansoprazole 15 mg is a suitable choice for management of frequent nighttime heartburn.
