title: Efficacy and safety of lansoprazole in adolescents with symptomatic erosive and non-erosive gastroesophageal reflux disease.
abstract: OBJECTIVE
  To assess the efficacy and safety of lansoprazole in the treatment of adolescents with symptomatic, endoscopically proven, non-erosive gastroesophageal reflux disease and erosive esophagitis.
  
  
  METHODS
  Adolescents between 12 and 17 years of age with esophagitis were enrolled in this open-label trial and treated with lansoprazole 15 mg (non-erosive) or 30 mg (erosive) once daily for 8 weeks. If unhealed at week 8, those with erosive esophagitis were treated with an additional 4 weeks of lansoprazole 30 mg once daily.
  
  
  RESULTS
  Lansoprazole produced a significant reduction from baseline in the median percentage of days with reflux symptoms (91 to 43% in the 64 adolescents with non-erosive disease and 85 to 16% in the 23 adolescents with erosive esophagitis, P < or = 0.001 for each comparison). At week 8, mucosal healing had occurred in 95% (21 of 22) of those with erosive esophagitis. Treatment-related adverse events were reported by 19% of patients with non-erosive and 4% of patients with erosive esophagitis. Headache (7%), abdominal pain (5%), nausea (3%) and dizziness (3%) were the most frequently reported adverse events. One patient discontinued treatment early because of dizziness and vomiting. An elevation in mean serum gastrin from baseline (59 pg/mL at pretreatment to 80 pg/mL at final visit) was observed.
  
  
  CONCLUSIONS
  Lansoprazole 15 mg or 30 mg once daily reduced symptoms of gastroesophageal reflux in adolescents with non-erosive gastroesophageal reflux disease and erosive esophagitis, respectively. Lansoprazole 30 mg once daily for 8 weeks was effective in healing erosive esophagitis. Both treatment regimens were considered safe.
