ABSTRACT
Tiagabine was used as add-on therapy in the treatment of epilepsy with partial and/or secondarily generalised seizures to evaluate tolerability and efficacy. Five hundred and seventy-four patients (299 men and 275 women, mean age 38.1 years), with refractory partial seizures, were enrolled in this prospective, open-label study. Tiagabine was added to one (44.1%) or more (up to nine) antiepileptic drugs. The median daily dose of tiagabine was 30 mg (mean 29.1, SD 12.0). The mean duration of follow-up was 94.9 42.7 days. 12.3% of patients were completely seizure-free at the end of the observation period. Median total seizure frequency decreased from 4.5 to 2.0 seizures/4 weeks. Adverse events occurred in 78 patients (13.6%). Tiagabine proved to be a well-tolerated AED.
