Vimpat is FDA-approved as adjunctive therapy for partial-onset seizures in patients 1 month and older, and as monotherapy for partial-onset seizures in patients 17 years and older. It is available as oral tablets, oral solution, and intravenous injection.
Vimpat works by selectively enhancing the slow inactivation of voltage-gated sodium channels in neurons, which helps stabilize hyperexcitable neural membranes and prevent repetitive neuronal firing associated with seizures.
Common side effects include dizziness, headache, and double vision. Vimpat may cause mood changes, depression, or suicidal thoughts and requires monitoring. It should not be stopped abruptly as this may increase seizure frequency. Patients should inform their doctor of all medications and health conditions before starting treatment.
