What is Carbamazepine?

Carbamazepine (CBZ) (Tegretol, cure Equetro) is an anticonvulsant and mood-stabilizing drug used primarily in the treatment of epilepsy and bipolar disorder, as well as trigeminal neuralgia. It is also used off-label for a variety of indications, including attention-deficit hyperactivity disorder (ADHD), schizophrenia, phantom limb syndrome, complex regional pain syndrome, paroxysmal extreme pain disorder, neuromyotonia, intermittent explosive disorder, borderline personality disorder, Myotonia congenita and post-traumatic stress disorder.

Like other anticonvulsants, intrauterine exposure is associated with spina bifida and neurodevelopmental problems.

Medical Use of Carbamazepine

Carbamazepine is typically used for the treatment of seizure disorders and neuropathic pain. It may be used as a second line treatment for bipolar disorder and along with antipsychotic agents in schizophrenia.

In the United States, the FDA-approved indications are epilepsy (including partial seizures and tonic-clonic seizures), trigeminal neuralgia, and manic and mixed episodes of bipolar I disorder. Although data are still lacking, Carbamazepine appears to be as effective and safe as lithium for the treatment of bipolar disorder, both in the acute and maintenance phase.

What is the 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.

How to dose Carbamazepine?

Usual Adult Dose for Epilepsy

Initial dose: 200 mg orally twice a day (immediate and extended release) or 100 mg orally 4 times a day (suspension).
Increase dose at weekly intervals in 200 mg/day increments using a twice daily regimen of extended release or a three times a day or four times a day regimen of the other formulations.

Usual Adult Dose for Trigeminal Neuralgia

Initial dose: 100 mg orally twice a day (immediate or extended release) or 50 mg orally 4 times a day (suspension).
May increase by up to 200 mg/day using increments of 100 mg every 12 hours (immediate or extended release), or 50 mg four times a day, (suspension), only as needed to achieve freedom from pain. Do not exceed 1200 mg/ day.
