[Double-blind study on the anti-convulsive effect of phenobarbital and valproate in the Lennox syndrome]
Insights
Valproate demonstrated superior anticonvulsant activity compared to phenobarbital in children with Lennox syndrome. This epilepsy treatment showed better seizure control with valproate, even with reduced phenobarbital dosage, and good tolerance.
Area of Science:
- Pediatric Neurology
- Clinical Pharmacology
- Epileptology
Background:
- Lennox syndrome is a severe form of childhood epilepsy.
- Anticonvulsant medications are crucial for managing epileptic seizures.
- Valproate and phenobarbital are commonly used antiepileptic drugs.
Purpose of the Study:
- To compare the anticonvulsive efficacy of valproate versus phenobarbital in pediatric Lennox syndrome.
- To assess the tolerance of valproate and phenobarbital in this patient population.
- To evaluate the impact of these drugs on EEG activity and behavior.
Main Methods:
- A double-blind, crossover trial was conducted.
- 17 children diagnosed with Lennox syndrome participated.
- Valproate was compared with phenobarbital, with a 40% reduction in phenobarbital dosage when used in combination.
Main Results:
- Valproate, combined with a reduced phenobarbital dose, showed statistically significant improvement in seizure control compared to phenobarbital alone.
- No significant differences were observed in the effects on electroencephalogram (EEG) tracings.
- Behavioral improvements were noted with valproate, though not statistically significant.
Conclusions:
- Valproate is a more effective anticonvulsant agent than phenobarbital for Lennox syndrome, even at reduced doses.
- Both valproate and phenobarbital exhibit comparable and good tolerance profiles.
- Further research may explore valproate's behavioral benefits in pediatric epilepsy.
Abstract:
In a double-blind crossover trial valproate was compared with phenobarbital with regard to anticonvulsive activity and tolerance in 17 epileptic children (mean age 55 +/- 26 months) with Lennox syndrome. Valproate in association with a phenobarbital dose reduced by about 40% proved to be to a statistically significant degree more active against epileptic seizures than phenobarbital alone. No difference in the effect on the EEG tracings was observed. Valproate appeared to be somewhat more active than phenobarbital with regard to behaviour, but the difference was not significant. Tolerance to both products was equally good.
