Efficacy and safety of antiepileptic therapy in children (a comparative analysis of valproates and barbiturates)
: The study aimed at a comparative analysis of safety and efficacy of valproic acid (valproate) and barbiturates in the treatment of epilepsy in children. Two hundred and forty children were treated with valproate, 94% being assigned to depakine and depakine chrono, and 210 children received barbiturates. Therapeutic effect (a decrease of seizures frequency by 2 and more times or remission) was detected in 82 of 127 (65 +/- 8.53%) patients for valproate monotherapy and only in 26 of 89 (30 +/- 9.45%) for barbiturates monotherapy. An efficacy of antiepileptic therapy in children was significantly higher (p<0.05) for valproates as compared to barbiturates. A drug withdrawal due to poor tolerability was recorded in 6 of 127 (5 +/- 3.7%) patients treated with valproate in monotherapy and in 14 of 210 (7 +/- 3.45%)--in polytherapy; in 53 of 89 (59 +/- 10.2%) patients treated with barbiturates in monotherapy and in 78 of 121 (65 +/- 8.53%) patients treated with barbiturates in polytherapy. Therefore, adverse effects occurred more often in barbiturates than in valproate treatment both for mono- and polytherapy (p<0.05). The results of the study confirmed the high efficacy and safety of valproates, specifically depakine chrono, in the treatment of epilepsy in children. depakine chrono in-take is associated with lower frequency of adverse effects; side-effects are mostly of dose-dependent character and do not result in the drug withdrawal. The authors do not recommend using barbiturates in the first-line treatment in children, because of the lower efficacy, high frequency of medical complications that might result in the drug withdrawal and reducing of the efficacy of other antiepileptic medications.
