Carbamazepine depresses activity in the nucleus ventralis of the thalamus, reduces synaptic propagation of excitatory impulses or decreases summation of temporal stimulation leading to neural discharge by limiting influx of Na ions across cell membrane or other unknown mechanisms. It stimulates the release of antidiuretic hormone (ADH) and potentiates its action in promoting reabsorption of water.
