Talampanel is a potent and selective AMPA-receptor antagonist, is a potential new antiepileptic drug (AED). Target: AMPA [1]in vitro: Talampanel is a glutamate receptor inhibitor with anti-seizure activity.in vivo: Talampanel reduces motoneuronal calcium in a mouse model of ALS, but its effi cacy declines as the disease progresses, suggesting that medication initiation in the earlier stages of the disease might be more effective.
