Mechanism of action

Lamotrigine stabilizes neuronal membranes by blocking sodium channels, which prevents repetitive neuronal firing. It also inhibits the release of glutamate, an excitatory neurotransmitter, thereby reducing excessive neuronal activity. These combined effects make it effective as an anticonvulsant and mood stabilizer.
