A trial of discontinuation of barbiturates in patients with secondary generalized epilepsy.
The vast majority of patients with secondary generalized epilepsy (SGE) were under polytherapy including barbiturates. We were able to completely withdraw barbiturates in 17 cases with a refractory course of SGE. Valproic acid (VPA) is considered as one of the best drugs for SGE. Barbiturates decrease the serum level of VPA and this may lead to a reduced efficacy of VPA. The dosage of VPA was adjusted to attain the level of 100-150 micrograms/ml. Barbiturates were then gradually decreased and finally discontinued. After six months of follow-up, 13 patients (76%) showed a reduced seizure frequency. Also, the physical and psychological conditions improved in a good number of cases. Barbiturates are not necessarily required in pharmacotherapy of SGE and may be safely withdrawn.
