Topiramate Approved as Antiepileptic Drug


TopiramateOn March 11, 2014 the FDA approved Topiramate, marketed as Qudexy™ XR by Upsher-Smith Laboratories, for the treatment of partial-onset seizures (POS) or primary generalized tonic-clonic seizures in patients 10+ years of age. It is also approved as adjunctive therapy in patients 2+ years of age for the aforementioned seizures, and seizures associated with Lennox-Gastaut syndrome.

The FDA approval was based on the phase III PREVAIL trial data, released late 2013 at the American Epilepsy Society 67th Annual Meeting.

Precisely 249 adult patients around the world participated in the PREVAIL trial, throughout at 66 centers. Trial results revealed the drug’s endpoints were met for efficacy. A significantly greater median percentage reduction in seizure frequency was observed compared with the placebo (39.5% vs 21.7%; P < .001.) The 50% responder rate was also greater (37.9% vs 23.2%; P = .013).

The new topiramate formulation can be prescribed in 25mg, 50mg, 100mg, 10mg, and 200mg extended-release capsules. The capsule contents can be sprinkled on soft food like applesauce to help dosing for patients who have a hard time swallowing the whole pill.
