What Is the Current Market for Lacosamide?
Lacosamide is an antiepileptic drug (AED) approved by the FDA since 2008 for the adjunctive treatment of partial-onset seizures in epilepsy patients. It is marketed under the brand name Vimpat by UCB.
The global epilepsy treatment market is valued at approximately $4 billion in 2022, with AED drugs accounting for about 30%. Lacosamide's contribution is estimated at $300-400 million annually, driven primarily by North American and European markets. Its market share among third-generation AEDs has increased from 8% in 2019 to 15% in 2022 [1].
