RESUMO
Background: Although epilepsy is a common neurological condition, there is paucity of nationwide data on treatment patterns and sociodemographic and clinical factors affecting treatment decisions in India. Objective: To assess clinical profiles, usage pattern of antiepileptic drugs (AEDs), and seizure control among patients with epilepsy in India. Methods: This was a cross-sectional, observational, multicenter study on adult patients with epilepsy who were on AEDs for at least six months before enrollment. Data were collected from patient interviews and medical records. Results: Out of 800 enrolled patients, a majority (69.0%) had generalized onset seizure in the six months before enrollment. The median age at epilepsy onset was 20.0 (1.0-64.0) years; 40.0% of the patients were females, 48.5% were married, 99.1% were literate, and 67.0% belonged to the lower or upper-middle socioeconomic class. Overall, 459 patients (57.4%) received AEDs as combination therapy. Most patients received levetiracetam (37.0%), sodium valproate (18.5%), carbamazepine (17.3%), or phenytoin (13.8%) as monotherapy, and clobazam (59.7%), levetiracetam (52.9%), carbamazepine (26.4%), sodium valproate (24.8%), or phenytoin (24.0%) in combination therapy. Quality of life was comparable for first- and third-generation AEDs. Adverse drug reactions were mostly attributed to dose modification or switching between drugs. No serious adverse drug reactions or new safety concerns were identified. Conclusions: Findings from this large, cross-sectional, observational, multicenter study indicate that first-generation AEDs sodium valproate and phenytoin continued to be used in a substantial number of patients on monotherapy and combination therapy in India, even though an increasing trend toward use of second-generation AEDs was noted in clinical practice.
