Double-Blind Cross-Over Placebo Controlled Study of Flunarizine in Patients With Therapy Resistant Epilepsy

Abstract

Twenty-five patients with long-standing therapy resistant epilepsy were studied in an eight-month double- blind cross-over add-on trial with a daily dose of 15 mg flunarizine. In five patients the seizure frequency decreased 50% or more. The mean seizure frequency reduction in the patients on flunarizine was 35%. Particularly the control of secondary generalized seizures improved. Flunarizine did not significantly alter the plasma levels of the regular anticonvulsant drugs. Minimal adverse side effects were reported equally in the flunarizine and the placebo group. In three patients depressive symptoms improved and two patients became free of postictal headaches. Flunarizine appears to be a safe adjuvant anticonvulsant. © 1989, Canadian Neurological Sciences Federation. All rights reserved.
