Clobazam was compared with placebo as antiepileptic adjunct medication in 129 therapy-resistant epileptic patients who were mainly suffering from complex partial seizures. The study was performed in five European countries according to a double-blind crossover design lasting 7 months. Two treatment periods of 3 months (1 month adjustment and 2 months maintenance medication) were separated by one medication switch-over month.
