Tiagabine blocks the uptake by neurons or glia of synaptically released GABA resulting in prolonged GABAergic activity and decreased likelihood of epileptic seizures. We evaluated the cognitive and quality of life effects of tiagabine in a double-blind, add-on, placebo-controlled, parallel, multicenter, dose-response efficacy study in patients with focal epilepsy whose complex partial seizures were difficult to control. One hundred sixty-two patients provided cognitive and quality of life data for the analyses and received the following treatments: placebo (n = 57), 16 mg/d tiagabine (n = 34), 32 mg/d tiagabine (n = 45), or 56 mg/d tiagabine (n = 26) at a fixed-dose for 12 weeks after a 4-week dose titration period. Eight cognitive tests and three measures of mood and adjustment were administered during the baseline period and again during the double-blind period near the end of treatment (or at the time of dropout). The patient groups were similar at entry into the study. Results showed no clinically important changes with the addition of tiagabine on the test battery. Although this is an encouraging finding, it remains for future investigations to determine the cognitive and behavioral effects of tiagabine either as monotherapy or in relation to other antiepileptic drugs.
