Eslicarbazepine is primarily used as an antiepileptic drug for the treatment of partial-onset seizures in adults. It works by stabilizing the inactive state of voltage-gated sodium channels, which helps reduce neuronal excitability and prevents the spread of seizures. This medication is often prescribed when other treatments have not been effective or are not well-tolerated. It is available in oral tablet form and is typically taken once daily, making it convenient for patients. Eslicarbazepine is also being studied for its potential use in other neurological conditions, though its primary application remains in epilepsy management. Patients are usually monitored for side effects such as dizziness, drowsiness, and hyponatremia during treatment.
