Biological Activity for Carbamazepine

Carbamazepine is an inhibitor of neuronal voltage-gated Na+ channels. Exhibits anticonvulsant activity. Potentiates GABA-induced Cl- currents in HEK 293 cells expressing the GABAA receptor α1β2γ2 subtype combination. Can induce autophagy by inhibiting inositol synthesis. Also delays disease onset and prolongs survival in a mouse amyotrophic lateral sclerosis (ALS) model, as well as reducing motor neuron loss and altered muscle morphology.

Carbamazepine's effect on serotonin systems observed.

Carbamazepine's effect on serotonin systems observed and an attempt to explain how it exert it's antiseizure effects was made.

There is evidence that it is a serotonin releasing agent and possibly even a serotonin reuptake inhibitor
