Carbamazepine 400mg XR

Carbamazepine 400mg XR Uses

Carbamazepine 400mg XR is prescribed to manage:

• Epilepsy: Controls partial and generalized tonic-clonic seizures effectively over extended periods.
• Trigeminal Neuralgia: Provides sustained relief from severe facial nerve pain.
• Bipolar Disorder: Stabilizes mood swings, helping to prevent manic and depressive episodes.

This extended-release formulation is ideal for individuals who need steady therapeutic effects with minimal dosing frequency.

How Does Carbamazepine 400mg XR Work?

Carbamazepine 400mg XR contains the active ingredient Carbamazepine, which regulates abnormal electrical activity in the brain. It works by blocking sodium channels in nerve cells, slowing the rapid firing of electrical signals that cause seizures and nerve pain. For bipolar disorder, it stabilizes neurotransmitter activity, helping to maintain emotional balance.

The extended-release formulation ensures a gradual release of the medication into the bloodstream, maintaining consistent drug levels for prolonged therapeutic benefits.
