Objective The aim of this study was to determine the outcome of antiepileptic drug (AED) treatment based on seizure freedom, pharmacovigilance reports and effects of concomitant medication on the central nervous system (CNS) of adult epileptic patients registered in the East-Hungarian Epilepsy Database. Methods Prospective cross-sectional database was compiled from outpatient files between 1992 and 2011. Results The majority of 1282 treated patients were on monotherapy 894 patients (70%), 286 (22%) on bitherapy and 102 (8%) on polytherapy. Of all treated patients, seizure freedom was achieved by 603 (47%). Among the seizure free patients 464 (77%) were on monotherapy, 115 (19%) on bitherapy and only 24 (4%) on polytherapy. The overall rate of adverse drug reactions (ADRs) was 16.2%. From patients on AED, 279 (22%) took concomitant drugs acting on the CNS. In a logistic regression model, other CNS-related drugs and a number of prescribed antiepileptic drugs had a significant influence on the desired outcome of seizure freedom. On comparing the Proportional Reporting Ratio and 95%CI of older and newer AEDs, no significant superiority of newer AEDs was detected. Conclusion Careful drug selection for epileptic patients must be highlighted in order to improve outcome, reduce ADRs and improve patient compliance.
