Eradication of Helicobacter pylori with pantoprazole and two antibiotics: a comparison of two short-term regimens.

BACKGROUND: High rates of Helicobacter pylori eradication can be achieved by combining proton pump inhibitors with two antibiotics. However, in the search for an optimal therapy a direct comparison of different regimens is necessary. METHODS: For this open study, 331 patients with duodenal ulcer were screened and randomly allocated to either pantoprazole 40 mg b.d., clarithromycin 500 mg b.d., and metronidazole 500 mg b.d. (PCM) or pantoprazole 40 mg b.d., amoxycillin 1000 mg b.d., and clarithromycin 500 mg b.d. (PAC) for 7 days. Both combinations were followed by a 7-day therapy with pantoprazole 40 mg o.d. alone. Eradication of H. pylori was assessed by use of a 13C-urea breath test 4 weeks after the intake of the last medication. RESULTS: Eradication rates were 90% in intention-to-treat patients from the PCM (132 out of 147; 95% CI: 84-94%) and the PAC group (135 out of 150; 95% CI: 84-94%). H. pylori was eradicated in 112 out of 117 per protocol patients of the PCM group (96%; 95% CI: 90-99%) and in 119 out of 126 patients of the PAC group (94%; 95% CI: 89-98%). Rapid relief from ulcer pain and a decrease in the mean intensity of other gastrointestinal symptoms was observed. Sixty-nine patients reported adverse events, none of which were related to the intake of pantoprazole. Four serious adverse events, none related to the trial medication, were observed. CONCLUSIONS: Both pantoprazole-based short-term triple therapies are highly effective and well-tolerated treatment regimens in the eradication of H. pylori.

A multi-centre, randomised, double-blind, placebo-controlled clinical trial on the efficacy and tolerability of GeloMyrtol® forte in acute bronchitis.

UNLABELLED: GeloMyrtol® forte (Myrtol®) is a phytomedicine obtained by distillation from essential oils. The trial was conducted to confirm the efficacy of Myrtol® in the treatment of acute bronchitis. METHODS: Patients with acute bronchitis and without confounding co-morbidity or co-medication were randomly assigned to treatment with either Myrtol® 300 mg 4 times daily or matched placebo in double-blind, parallel-group fashion. Signs and symptoms were evaluated by the investigator at baseline and after 7, 10 and 14 days of treatment; intake of medication, wellbeing and symptoms were recorded daily by the patient in the patients' diaries. FINDINGS: 413 patients were enrolled and randomised (Myrtol®: 202; Placebo: 211); 398 had at least one on-treatment efficacy evaluation (Myrtol®: 196; Placebo: 202). The mean change in coughing fits from D01 (baseline) to D07-D09 (after about one week treatment) was 62.1% (95% CI: 57.6-66.6%) and 49.8% (95% CI: 44.6-55.0%) for treatment with Myrtol® and placebo, respectively (p<0.0001). With Myrtol®, the median time to 50% reduction in coughing fits was statistically significantly shorter and there were more patients without day-time coughing fits; there also were statistically significantly less day-time coughing fits, less difficulty coughing up, less sleep disturbance due to night-time coughing; with Myrtol® there was less symptomatic impairment (composite bronchitis severity score and subscores) and significant more patients had a clinically satisfying response to the investigational treatment.Both treatments were generally well tolerated. CONCLUSIONS: Myrtol® is statistically significantly superior to placebo in treating acute bronchitis.
