ABSTRACT
Lamotrigine is a newer antiepileptic drug useful as oral adjunctive therapy in refractory epilepsy. Indian data on use of lamotrigine is limited. This study was conducted to evaluate add-on lamotrigine in Indian children with epilepsy. Twenty children (median age 90 months) receiving lamotrigine as add-on therapy for mean 26.7 (19.1) months, were followed for a median period of 7.9 (6-10) months. Follow-up was done every two weeks. The most common seizures types were either generalized tonic-clonic (6, 30%) or myoclonic (8, 40%). The average dose used was 3.86 mg/kg/day (with concomitant valproate). Good response (>50% reduction) or complete seizure control was seen in 72% patients. Side effects were seen in 27.5% patients and were ‘mild’ in more than half of these. Lamotrigine was stopped in two patients due to adverse reactions, which resolved on stopping the drug. Lamotrigine was observed to be an effective, add-on, broad-spectrum antiepileptic with ‘mild’ side effects in Indian children.
ABSTRACT
Objective. To evaluate the efficacy of clobazam in childhood refractory epilepsy and to characterize the adverse drug reaction profile in the Indian population. Methods. A cohort of 88 children with ‘refractory’ epilepsy was started on clobazam as add-on therapy. Diagnosis was established and seizure type recorded. Therapeutic response was recorded as ‘complete’, ‘good’, and ‘no response’. Observed side effects were classified as ‘mild’, ‘moderate’ and ‘severe’. Results. Most children were on at least two antiepileptics. Seizures most identified were either partial (36.3%) or generalized tonic-clonic (15.9%). The dose ranged from 0.3-2 mg/kg/day (average 1+0.2 mg/kg/day). Clobazam was effective against all seizure types with complete seizure control seen in 60.2% patients. Tolerance was seen in 5 (5.6%) patients. Side effects were seen in 23 (26%) patients and were ‘mild’ in 20 (86.9%) of them. Clobazam was stopped in three patients who developed ataxia, which resolved on stopping the drug. Conclusion. Clobazam was observed to be an effective broad-spectrum antiepileptic with ‘mild’ side effects in Indian children.
