Talampanel

Chemical compound

Talampanel (INN; development codes GYKI 537773 and LY300164) is a drug which has been investigated for the treatment of epilepsy,[1][2] malignant gliomas,[3] and amyotrophic lateral sclerosis (ALS).[4]

Quick Facts Clinical data, ATC code ...

As of May 2010, results from the trial for ALS have been found negative.[5] Talampanel is not currently under development.

Talampanel acts as a non-competitive antagonist of the AMPA receptor, a type of ionotropic glutamate receptor in the central nervous system.[6]

It showed effectiveness for epilepsy in clinical trials but its development was suspended due to its poor pharmacokinetic profile, namely a short terminal half-life (3 hours) that necessitated multiple doses per day.[7]
