Veratridine causes deplorization of excitable cells and produces marked elevation of adenosine 3',5'-monophosphate (cyclic AMP) and guanosine 3',5'-monophosphate (cyclic GMP) levels in incubated slices of mouse cerebral cortex. Phenytoin, carbamazepine, phenobarbital, primidone, phensuximide, methsuximide, alpha-methyl-alpha-phenylsuccinimide, and high concentrations of clonazepam are anticonvulsant drugs that preferentially prevent maximal electroshock seizures (MES) and generalized tonic-clonic convulsions; all these agents inhibit veratridine-induced accumulation of both cyclic AMP and cyclic GMP. In contrast, ethosuximide, trimethadione, valproic acid, and low concentrations of clonazepam are anticonvulsant drugs that act predominantly against Metrazol and absence seizures; these agents are ineffective or inhibit accumulation of only cyclic GMP. The results suggest that inhibition of cyclic AMP and cyclic GMP accumulation in depolarized brain tissue is a molecular neuropharmacological action characteristic of anticonvulsant drugs that have direct effects on cellular membrane function and prevent MES. Anticonvulsant drugs that do not inhibit accumulation of both cyclic AMP and cyclic GMP in depolarized brain tissue preferentially prevent Metrazol and absence seizures and probably exert their effects by altering neurotransmission mechanisms.
