Topiramate-13C6 is the 13C labeled form of Topiramate. Topiramate (T0675) (McN 4853) serves as a broad-spectrum antiepileptic agent. It functions as a GluR5 receptor antagonist and exhibits anticonvulsant effects by enhancing GABAergic activity, inhibiting kainate/AMPA receptors, blocking voltage-sensitive sodium and calcium channels, increasing potassium conductance, and inhibiting carbonic anhydrase.
