How does lamotrigine work?
Lamotrigine functions by stabilizing electrical activity in the brain and altering chemical messengers called neurotransmitters [3]. It is believed to work by blocking voltage-sensitive sodium channels, which in turn inhibits the release of glutamate, an excitatory neurotransmitter [3]. This action helps to prevent the excessive firing of neurons that can lead to seizures or mood swings [3].
