To evaluate the effect of topiramate in elderly patients with onset of epilepsy after the age of 60, treatment-naive or non-responding to an initial antiepileptic drug.
Analysis of patients with epilepsy diagnosed in the preceding 5 years, aged>/=65 years (n=43), enrolled in a larger open-label trial (n=692). After titration to topiramate 100 mg/day over 4 weeks, the dose was adjusted according to individual response (maximum 400 mg/day). Patients were followed up for at least 7 months.
After 7 months, 79% of patients remained in the study. Seizure frequency decreased significantly vs baseline (P<0.001); >/=50% reduction in seizure frequency was achieved in 87% of patients, 64% remained seizure-free. Both previously treated and naive patients responded. Fourteen per cent dropped out because of insufficient tolerability. No unexpected or unusual adverse events were observed.
The results indicate that elderly patients respond well to topiramate monotherapy. The high patient retention rate reflects a favourable tolerability profile in this population.
