Primary Outcome Measures
NameTimeMethod
Main Objective: The purpose of this study is to compare the effectiveness and safety of two treatment regimens, topiramate as compared to phenytoin, in preventing seizures in patients with new-onset epilepsy who require rapid initiation of antiepileptic drug therapy. Reasons for requiring rapid initiation of treatment, rather than slowly increasing an antiepileptic drug to an effective dose, may include severe or frequent seizures, or high risk to the patient of recurrent seizures.;Secondary Objective: None;Primary end point(s): The primary outcome parameter is the time to first seizure during the double blind phase of the study. The statistical evaluation will analyze if there is a significant difference in the proportion of patients being seizure free between both medications.;Timepoint(s) of evaluation of this end point: Throughout the study duration
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): Effect of sex, age, baseline weight, baseline seizure type, and duration since first diagnosis of epilepsy on the time to seizure.;Timepoint(s) of evaluation of this end point: Throughout the study duration
