Clinical Significance

Clinical Use: Carbamazepine and its metabolite, (10,11- Carbamazepine epoxide), are widely used for control of generalized tonic-clonic, partial-onset, complex and mixed seizure disorders. The metabolism of carbamazepine in epileptic patients has several different pathways that can be altered when the patient is co-medicated with other anticonvulsants and, therefore, its therapeutic level should be monitored along with its metabolite in their free and protein bound states.
