Carbamazepen is an anticonvulsant used to control grand mal and psychomotor or focal seizures. It may be related to its ability to increase the inactivation of sodium channels, to limit postsynaptic neurons and block the presynaptic Na + channels, thereby limiting the presynaptic neurons after the action potential Dispensing, blocking the release of excitatory neurotransmitters so that the excitability of nerve cells decreased to achieve the role of anticonvulsant.
