The anticonvulsant effects of amitriptyline, imipramine, nortriptyline and desipramine were tested against focal and generalized seizures, triggered from either the amygdala or the cortex in fully kindled rats. Tests were administered on a 72- or a 24-hour schedule. Significant seizure suppression was achieved with only one drug, amitriptyline, and it occurred only at toxic or near-toxic doses. The differential, low-dose suppression of amygdala-kindled seizures, reported in earlier studies, was not seen in the present experiments. It may occur only in the short-interval test paradigms used by previous experimenters.
