[Central action of a new cholinesterase reactivator, diethyxime].
In anesthetized cats, whose peripheral muscarinic-cholinorecptors are blocked by m-cholinolytics (benzilyl choline) failing to penetrate into the brain, the cholinesterases reactivator diethyxime debars the centrally caused fall of the arterial pressure produced by armine, an inhibitor of cholinesterases readily gaining access into the brain. Diethyxime is also capable of abolishing the depression of the phrenic nerve action potentials produced by armine. Dipyroxime-a quaternary diethyxime analogue and also a quaternary cholinesterase reactivator fails to produce such an effect.
