[Anti-arrhythmia activity of derinat in an experiment]. / Protivoaritmicheskaia aktivnost' derinata v éksperimente.

The acute toxicity of the immunostimulant derinat is very low: the LD50 value for intraperitoneal administration exceeds 1000 mg/kg. The drug effectively prevents from acute arrhythmia development upon occlusion in cats and produces antifibrillator effect on a model of reperfusive arrhythmia in a dose of 7.5 mg/kg. Derinat also exhibits the antiarrhythmic activity on the model of adrenalin-induced rhythm violations, but appears ineffective on the calcium chloride model.
