Lamotrigine SR 150mg

Lamotrigine SR 150mg Uses

Lamotrigine SR 150mg is prescribed to: Treat epilepsy – Used alone or with other medications to manage partial and generalized seizures, including Lennox-Gastaut syndrome. Prevent bipolar disorder episodes – Helps stabilize mood and prevent extreme mood swings in bipolar I disorder. Reduce seizure frequency – Provides consistent control for individuals with seizure disorders. Minimize side effects – The sustained-release formula ensures gradual drug absorption, reducing sudden peaks and side effects.

How Does Lamotrigine SR 150mg Work?

Lamotrigine SR 150mg works by stabilizing electrical activity in the brain. Its mechanism includes: Inhibition of voltage-gated sodium channels – Prevents overactive nerve firing that causes seizures and mood instability. Glutamate regulation – Reduces the release of glutamate, an excitatory neurotransmitter that contributes to seizures and mood disorders. Extended-release action – Allows for slow, controlled drug release, ensuring consistent blood levels throughout the day. By reducing nerve excitability, Lamotrigine SR 150mg effectively prevents seizures and mood disturbances.
