• The antiepileptic effects of carbamazepine and phenytoin were compared in a double-blind crossover trial studying patients with primary and secondary generalized seizures and partial seizures with motor symptoms. Each treatment period lasted ten weeks. The patients were seen every two weeks, and doses were adjusted according to plasma levels. It was attempted to keep levels in the optimal plasma range, ie, 10 to 20 and 4 to 10 mg/liter for phenytoin and carbamazepine, respectively. Twenty-three patients entered and 19 completed the study. No statistically significant differences were found between carbamazepine and phenytoin with regard to seizure control and acute side effects.
