Introduction: Topiramate (TPM) is a new antiepileptic drug with multiple modes of action which should theoretically represent a wide therapeutic spectrum. However, there is still little clinical experience of its use in children with epilepsy.
Patients and methods: TPM was given during a period of 14.8 +/- 15.4 months, at an average dose of 6.6 +/- 2.5 mg/kg/day to 44 children with resistant epilepsy. They included 21 children with Lennox-Gastaut syndrome, 14 with partial epilepsy, 7 with multifocal epilepsy, one with polymorphic epilepsy and one with electrical changes during sleep.
Results: When TPM was associated with their treatment, a response of > 50% reduction in epileptic crises was seen in 76% of the cases (85% with Lennox-Gastaut syndrome, 64% with partial epilepsy, 71% with multifocal epilepsy) and suppression of crises in 12% of the cases (5% with Lennox-Gastaut syndrome, 21% with partial epilepsy and 14% with multifocal epilepsy). The drug was well tolerated and only stopped because of side-effects in 4.5% of the cases.
Conclusions: TPM is an antiepileptic drug with a broad therapeutic spectrum, good clinical efficacy in children and is well tolerated by them.
Objetivo Valorar la eficacia y la tolerabilidad del TPM en niños con epilepsias rebeldes.
Pacientes y métodos Durante 14,8±15,4 meses se ha asociado TPM, con dosis medias de 6,6±2,5 mg/kg/día, a 44 niños con epilepsias rebeldes, en concreto a 21 niños con síndrome de LennoxGastaut, 14 con epilepsias parciales, 7 con epilepsias multifocales, uno con epilepsia polimorfa y uno con estado eléctrico durante el sueño.
Resultados La asociación de TPM logra una tasa de respondedores, es decir, con reducción de >50% de crisis, del 76% (85% con síndrome de Lennox-Gstaut, 64% con epilepsias parciales, 71% con epilepsias multifocales) y la supresión de las mismas en el 12% de casos (5% con síndrome Lennox-Gastaut, 21% con epilepsias parciales y 14% con epilepsias multifocales), con una buena tolerabilidad del fármaco, que sólo se anula en un 4,5% de casos por efectos adversos.
Conclusión El TPM es un fármaco antiepiléptico de amplio espectro terapéutico, con buena eficacia clínica en niños y con buena tolerabilidad
