A review of the efficacy and safety of extended-release topiramate in the adjunctive treatment for refractory partial-onset seizures

Topiramate has been widely utilized worldwide as an effective medication against partial- and generalized-onset seizures. Extended-release topiramate was developed to provide patients with the convenience of once-daily dosing and potentially improved tolerability by reducing serum concentration fluctuation. USL255 is a once-daily, extended-release formulation of topiramate, which was recently approved in the USA. Compared with immediate-release topiramate taken twice daily, once-daily USL255 provides equivalent topiramate exposure with a 26% reduction in plasma fluctuations. A multinational, phase III, randomized, double-blind, placebo-controlled clinical trial in patients with refractory partial-onset seizures demonstrated that USL255 (200 mg/day) significantly improved seizure control and was well tolerated with low overall neuropsychiatric and neurocognitive adverse events.
