Evaluating Lacosamide in the management of focal Seizures: A narrative review of Efficacy, safety and Tolerability

The focal seizures are one of the most widespread ones as they include various scopes of physical and psychological changes with a significant adverse impact on their well-being. Ever since anti-epileptic drugs (AEDs) are identified as a first-line treatment method, numerous patients encountered drug resistance and side effects. Lacosamide belongs to the third generation of anti-epileptic medication and is the best drug of the potential and preferred choice in treatment of focal seizures alone or as companion ecunicides. This narrative assessment examines the safety, effectiveness, tolerability, and clinical use of lacosamide in the treatment of epilepsy, drawing from 13 studies published from 2020 to 2024. All the studies revealed effectiveness of Lacosamide in reducing the frequency of the seizures with dose response and increase in the response rate over placebo. Additionally, it had an improved safety record and few adverse effects when compared to other antiepileptic drugs, particularly, among young individuals. The mode of action is selective in that; it amplifies the slow inactivation of sodium channels and causes minimal interference to the normal neural firing leading to fewer side effects and maximum control of seizures. Based on long-term studies, the efficacy of lacosamide is proven with continued seizure reduction and improved quality of life and cognitive status in both usage as monotherapy or adjuvant treatment. Even with all positive results, it has some challenges including clinicians' unfamiliarity with newer medications, expense-related factors and refusal to undergo treatment. To promote the clinical use of lacosamide on a large scale, eliminating these barriers by patient education, directing policy changes, and increasing access is vitally necessary. Altogether, lacosamide is a significant step towards treating focal epilepsy, and, given the effective safety balance, it could have a favorable influence on both patient outcomes and their livelihood.
