pharmachologic effect

Antiepileptic agent, derivative of tricyclic iminostilbene. It is believed that anticonvulsant action is associated with a decrease in the ability of neurons to maintain a high frequency of development of repeated action potentials through inactivation of sodium channels. In addition, it seems that inhibition of the release of neurotransmitters by blocking the presynaptic sodium channels and the development of action potentials, which in turn reduces the synaptic transmission, is important.

Has a moderate antimanic, antipsychotic effect, as well as analgesic effect with neurogenic pain. The mechanisms of action may involve GABA receptors, which may be associated with calcium channels; Also, apparently, the effect of carbamazepine on the systems of neurotransmitter modulators is important.

The antidiuretic effect of carbamazepine may be associated with a hypothalamic effect on the osmoreceptors, which is mediated through the secretion of ADH, and is also due to direct action on the renal tubules.

Indications
