Notes: Topiramate-d12 is intended for use as an internal standard for the quantification of topiramate (Item No. 13623) by GC- or LC-MS. Topiramate is a sugar sulfamate with anticonvulsant activity.{18290} It inhibits carbonic anhydrase in intact human erythrocytes (Ki = ~200 μM), as well as blocks sodium and calcium channels and kainate-induced currents in vitro.{18290,32575,48075} It also increases GABAA receptor-mediated chloride ion flux.{48075} Topiramate inhibits hind-limb tonic-extensor seizures in the maximal electroshock seizure test in mice (ED50 = 39 mg/kg, p.o.).{18290} Formulations containing topiramate have been used in the treatment of epilepsy and prophylaxis of migraine headaches.
