[Peripheral cholinolytic action--one of the effects of sidnofen].

Intravenous bolus injection of sydnophen (0.002-20 micrograms/kg) resulted in decrease or complete abolition of bradycardia induced by electrical stimulation of vagal peripheral end of anesthetized cats. The cholinolytic effects are dose-dependent.

[The possibility of peripheral cholinolytic action of psychostimulants].

The cholinolytic effect of sydnophen discovered in earlier anesthetized cats was confirmed on unanesthetized fish and frogs: the vagal bradycardia induced by electric stimulation of peripheral vagal end was decreased or even abolished by intravenous injection of sydnophen (0.2-20 mg/kg). The amphetamine (0.
