Oxcarbazepine: The Anticonvulsant for Seizure Disorders
Introduction: What is Oxcarbazepine?
Oxcarbazepine is an anticonvulsant used to treat epilepsy and seizure disorders. It is mainly used to control partial seizures in adults and children and is often used as an alternative to carbamazepine, another anticonvulsant.
How Oxcarbazepine Works
Oxcarbazepine works by stabilizing the neuron membrane and inhibiting the excessive firing of neurons. It blocks sodium channels, which prevents the abnormal electrical activity that causes seizures.
