[Pirenzepine parenterally administered in high doses in the treatment of upper digestive hemorrhage]

22 patients with moderate and severe haemorrhages of the UAC were given endovenous doses of Pirenzepine (100 mg/48 hrs). The drug was effective in 86% of the cases and its effect on pH values was demonstrated by testing before and after administration (p less than 0.01). Better results were observed in the treatment of patients with moderate and severe DUS.
