🧠💊 Oxcarbazepine 450mg Tablet: Seizure Control & Mood Stabilization

Oxcarbazepine 450mg is an anticonvulsant (anti-seizure) medication primarily prescribed to manage epilepsy and partial seizures, either alone or in combination with other medications. It is also occasionally used off-label as a mood stabilizer in certain psychiatric conditions. Oxcarbazepine is a structural derivative of carbamazepine but is often preferred for its fewer side effects and improved tolerability.

🔬 Mechanism of Action

Oxcarbazepine works by stabilizing overactive nerve signals in the brain. It blocks voltage-sensitive sodium channels, thereby reducing the repetitive firing of neurons that leads to seizures. After ingestion, it is rapidly converted to its active form — 10-monohydroxy derivative (MHD) — which is primarily responsible for the antiepileptic effect.
