Topiramate calciumProduct ingredient for Topiramate
- Name
- Topiramate calcium
- Drug Entry
- Topiramate
Topiramate is a anti-epileptic drug used to manage seizures and prevent migraines.4 It was initially approved by the FDA in 1996. In 2004, topiramate was approved for the prevention of migraine in adults.6,19,23 Since 2012, the extended-release formulation has been approved in combination with phentermine for chronic weight management therapy in adults.21
Characteristics that distinguish topiramate from other antiepileptic drugs are a monosaccharide chemical structure containing a sulfamate, and 40% of its mass accounted for by oxygen.4 Interestingly, topiramate was discovered by chance when attempts were made to formulate a novel antidiabetic drug.8
