Pharmacology
Fenfluramine and its metabolite norfenfluramine exhibit agonist activity at serotonin 5-HT2 receptors; the precise mechanism by which this produces antiseizure effects in Dravet syndrome and Lennox-Gastaut syndrome is unknown, though 5-HT2B receptor agonism is associated with valvular heart disease and pulmonary arterial hypertension risk.
Topiramate blocks voltage-dependent sodium channels, augments GABA-A receptor activity, antagonizes the AMPA/kainate subtype of the glutamate receptor, and inhibits carbonic anhydrase isozymes II and IV; the precise mechanisms underlying its anticonvulsant and preventive migraine effects are unknown.
