Safety and effectiveness in patients who were converted to monotherapy from a previous regimen of other anticonvulsant drugs have not been established in controlled trials. Topiramate tablets are indicated as adjunctive therapy for adults and pediatric patients ages 2 to 16 years with partial onset seizures, or primary generalized tonic-clonic seizures, and in patients 2 years of age and older with seizures associated with Lennox-Gastaut syndrome.

It is freely soluble in acetone, chloroform, dimethylsulfoxide, and ethanol. The solubility in water is 9.8 mg/mL. Its saturated solution has a pH of 6.3. Topiramate has the molecular formula C H NO S and a molecular weight of 339.37. Topiramate is designated chemically as 2,3:4,5-Di-_O_-isopropylidene-β-D- fructopyranose sulfamate and has the following structural formula: Topiramate tablets contain the following inactive ingredients: anhydrous lactose, microcrystalline cellulose, pregelatinized starch, sodium starch glycolate, magnesium stearate, purified water, polyvinyl alcohol, titanium dioxide, polyethylene glycol and talc.

Electrophysiological and biochemical evidence suggests that topiramate, at pharmacologically relevant concentrations, blocks voltage-dependent sodium channels, augments the activity of the neurotransmitter gamma-aminobutyrate at some subtypes of the GABA-A receptor, antagonizes the AMPA/kainate subtype of the glutamate receptor, and inhibits the carbonic anhydrase enzyme, particularly isozymes II and IV.
