Background:Clobazam is a benzodiazepine with known antiepileptic action; however, it is not considered first line therapy in the treatment of epilepsy. The objective of this study was to evaluate the efficacy of clobazam as add-on therapy in adults with temporal lobe epilepsy associated with MRI evidence of hippocampal sclerosis (HS).Method:This is a retrospective study, conducted at our epilepsy clinic which evaluated clobazam as add-on therapy in patients with temporal lobe epilepsy and MRI signs of HS. Clobazam was prescribed based on the minimum effective dose up to the maximum tolerated dose.Results:Seventy-eight patients met the inclusion criteria (51 women), ages ranging from 16 to 76 years old (mean=42.2). Dosage of clobazam ranged from 5 to 60 mg/day (mean=22.6 mg/day). Clobazam was used from one month to eight years (mean=29 months). Sixteen (20.5%) patients were seizure-free, 20 (25.5%) had more than 75% improvement in seizure control, eight (10%) had more than 50% and 20 (26%) were non responders to clobazam. In 14 (18%) we could not determine seizure frequency during follow-up. The improvement in seizure control lasted for more than one year in 30 (68%) patients.Conclusion:Our data suggest that clobazam should be considered as add-on therapy in the treatment of patients with temporal lobe epilepsy associated with MRI signs of HS.
