Introduction:
Medication-resistant epilepsy (MRE) is characterized by the failure of adequate trials of two antiseizure medications (ASMs). Numerous studies have shown that once two ASMs fail to control seizures, the likelihood of subsequent ASM regimens providing seizure control diminishes significantly. Recent clinical data on cenobamate (CNB) suggest it may offer higher rates of seizure freedom in MRE patients. This study aims to report real-world, single-center findings on the effectiveness and tolerability of CNB in treating MRE.
Methods:
This retrospective study includes adult patients diagnosed with MRE and treated with CNB between 2020 and 2023 at The George Washington University (GWU). Data were collected from electronic medical records. Statistical analyses were conducted to evaluate CNB's impact on seizure control and patient outcomes.
Results:
121 patients with medication-resistant epilepsy (MRE) were prescribed cenobamate (CNB). After exclusions, 104 patients were included in the effectiveness analysis and 111 in the tolerability analysis. Results showed that 34.6 % of patients achieved seizure freedom for at least three months, with a mean duration of seizure freedom of 11 ( ± 7.9) months.
Significance:
CNB use in a large population of more than 100 patients demonstrated impressive anti-seizure activity with a good proportion of patients with MRE achieving seizure freedom despite having failed multiple prior ASMs.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
