Topiramate is an anticonvulsant that antagonizes GluR5 receptors and acts as a positive allosteric modulator of GABA receptor-mediated currents. Target: GluR5 receptor; GABA receptor Topiramate (Topamax) is a structurally novel broad-spectrum antiepileptic drug (AED) with established efficacy as monotherapy or adjunctive therapy in the treatment of adult and paediatric patients with generalised tonic-clonic seizures, partial seizures with or without generalised seizures, and seizures associated with Lennox-Gastaut syndrome [1]. topiramate has been believed to be a type of antiepileptic drug that blocks spread of seizures. Thus far, the mechanisms of its actions have been proven to include use-dependent inhibition of voltage-dependent Na+ channels in neurons, potentiation of GABA (gamma-amino-butyric acid)-induced Cl- influx, and inhibitory effects on inward currents by antagonizing kainate/alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptors [2]. Topiramate (median average dosage 5.1 mg/kg/day) was also found to be useful as adjunctive therapy in the management of Lennox-Gastaut syndrome and significantly reduced the mean frequency of drop attacks by 14.8% compared with an increase of 5.1% with placebo. Further gains in seizure control were made in a nonblind extension of this trial where the mean topiramate dosage was 10 mg/kg/day. Nine of 11 patients in 1 pilot trial of children with otherwise intractable West syndrome, and 5 of 10 in another, achieved a > or =50% reduction in seizure rate with topiramate (target dosage up to 24 mg/kg/day) [3]. Clinical indications: Epilepsy; Lennox Gastaut syndrome; Migraine; Seizure disorder Toxicity:abdominal pain; agitation; blurred vision; convulsions; depression; dizziness; double vision; drowsiness; impaired coordination; impaired mental activity; low blood pressure; reduced consciousness; severe diarrhea; sluggishness and speech problems.
