title: Protective effect of creatinol O-phosphate (COP) on ventricular fibrillation and death induced by intravenous CaCl2 in mice.
abstract: The activity of N-methyl-N-(beta-hydroxyethyl)guanidine O-phosphate (creatinol O-phosphate, COP) on the acute toxicity of CaCl2 in mice was studied. The results obtained in the present investigation show that COP administered i.v. is able to antagonize, in a dose-dependent way, the lethal ventricular fibrillation provoked by CaCl2 in unanesthetized mice. Prenalamine and cinnarizine, two calcium antagonistic compounds, proved to be active in a way qualitatively similar to COP.
