Initiation of ESL versus BRV was associated with 33.3% lower all-cause pharmacy costs, 34.4% lower epilepsy-specific pharmacy costs, 21.3% lower all-cause total costs and 30.9% lower epilepsy-specific total costs (all p < 0.0001). <b>Conclusion: </b>Among patients with focal seizures in LTC in the US, initiation of ESL versus BRV was associated with significant reductions in all-cause and epilepsy-specific pharmacy and total costs compared with initiation of BRV.</p>
