Carbamazepine - Mechanism of Action

Mechanism of Action

The mechanism of action of carbamazepine and its derivatives is relatively well-understood. Carbamazepine stabilizes the inactivated state of Voltage-gated sodium channels, making fewer of these channels available to subsequently open. This leaves the affected cells less excitable until the drug dissociates. Carbamazepine has also been shown to potentiate GABA receptors made up of alpha1, beta2, gamma2 subunits.

    The action of the soul is oftener in that which is felt and left unsaid, than in that which is said in any conversation. It broods over every society, and they unconsciously seek for it in each other.
    Ralph Waldo Emerson (1803–1882)
