title: Helicobacter pylori, efficacy of the new triple therapy in six and twelve-day schedules.
abstract: OBJECTIVE
  Assessment of four eradicating patterns of 6 and 12 days duration with new triple therapies adapted to our environment.
  
  
  METHODS
  After an endoscopic diagnosis of Duodenal or Gastric Ulcer, and the confirmation of the presence of Helicobacter pylori using a rapid urease test in antral biopsies, 274 patients were treated with one of four eradicating therapies, verifying its efficacy with the C-13 urea breath test, at least one month after the end of the treatment and 10 days after withdrawal of proton pump inhibitors.
  
  
  RESULTS
  Maximum eradicating efficacy was achieved with Omeprazole (20 mg/12 hours), Clarithromycin (500 mg/12 hours) and Amoxycillin (1 g/12 hours), given for 12 days (96.6%), and Omeprazole (20 mg/12 hours), Tinidazole (500 mg/12 hours) and Clarithromycin (500 mg/12 hours), also given for 12 days (95.2%). The same drugs and doses, when given during six days, achieved percentages of 78.3% and 82.2% respectively. Results with Tinidazole suggest lack of resistance to this drug in the Community of Madrid.
