Topamax (Topiramate) is an anti-epileptic drug from the group of sulfamate-substituted monosaccharides. It is used to treat convulsions, epilepsy in children and adults, and also to prevent migraines and certain psychiatric conditions. The ability to suppress Topamax seizures is caused by the ability of its main active substance, topiramate, to block sodium channels in neurons, and suppress the potential for repetitive action in depolarizing neural cell membranes, and for a long time. The effect of Topamax is dose-dependent.
