Topiramate, 2,3:4,5-di-O-isopropylidene-β-d-fructopyranose sulfamate, is a potent antiepileptic drug with a broad spectrum of activity. It is effective in both partial and generalized seizures. Topiramate was also found to have significant efficacy in migraine prevention with considerable reductions in the frequency of migraine headaches. The most common adverse events, which may accompany the use of topiramate, are paresthesia, fatigue, decreased appetite, nausea, diarrhea, weight decrease and taste perversion. The weight loss observed with the use of topiramate in obese, epileptic patients, afforded the approval of this drug as an anti-obesity medication. This action is thought to be based on the selective inhibition of mitochondrial carbonic anhydrase isoforms. This profile is prepared to discuss and explain physical characteristics, proprietary and nonproprietary names of topiramate. It also includes methods of preparation, thermal and spectral behavior and methods of analysis. Pharmacokinetics, metabolism, excretion and pharmacology together with its uses and applications are also discussed.
