Description
Summary:Five antiepileptic drugs have been marketed in the last decade. We report here a retrospective study of patients attending our unit who were prescribed one of the new antiepileptic drugs. All these patients had refractory localization related epilepsy and had failed to respond to a first-line drug. The drugs had a different profile of side-effects but topiramate (42%) was the most common drug to be withdrawn due to side-effects as compared with tiagabine (26%), vigabatrin (16%), gabapentin (16%), and lamotrigine (15%). With regard to efficacy, 31% of the patients receiving gabapentin had a greater than 50% reduction in seizures compared with lamotrigine (25%), topiramate (20%), vigabatrin (19%) and tiagabine (11%). The number of patients remaining seizure free with gabapentin was 8% whilst for lamotrigine this was 5%, vigabatrin 5%, topiramate 1% and tiagabine 4%. In conclusion, all these five antiepileptic drugs are useful in treating refractory localization related epilepsy.
