Mechanism of action

Clobazam binds to GABA-A receptors on neurons, potentiating the effect of the inhibitory neurotransmitter GABA. This increases chloride ion influx and neuronal hyperpolarization, raising the seizure threshold and reducing the frequency and severity of seizures. It is a 1,5-benzodiazepine with a different structure from classical 1,4-benzodiazepines, which may contribute to its favorable tolerability profile in epilepsy.
