title: Effects of H2 blockers and omeprazole on peptic secretion: a prospective, randomized study in duodenal ulcer subjects.
abstract: Aim of the present study has been to investigate the possible modifications of peptic secretion after a period with H2 blockers and omeprazole, evaluating in the same patient pepsinogen group A levels in gastric mucosa and pepsin in gastric juice. 54 active duodenal ulcer were studied: during an upper gastrointestinal endoscopy a sample of gastric juice and one fundus biopsy were taken before and after four weeks 300 mg/daily ranitidine (23 patients), 40 mg/daily famotidine (7 patients), 300 mg/daily nizatidine (12 patients) therapy and 40 mg/daily omeprazole (12 patients) therapy.
  
  
  RESULTS
  H2-blockers and omeprazole treatment determines a non statistically significant decrease of pepsin in gastric juice and in pepsinogen group A in gastric mucosa.
