[Effect of benzonal on the resistance of animals to the action of organophosphorus and carbamic compounds].

The inductor of microsomal enzymes, benzonal (20 mg/kg) produces an overt preventive and treatment-preventive action in acute and subacute poisoning with organophosphorus (DDVP, parathion, TEPP, chlorophos) and carbamic (pirimor, sevin) compounds. As regards the efficacy benzonal is not inferior to phenobarbital (14 mg/kg). Pretreatment with benzonal averts the development of the neuromuscular blockade and normalizes spontaneous activity of the myoneural synapse of rats and cats poisoned with pirimor and parathion.
