How Britzilam SR 100 Tablet Works

Britzilam SR 100 Tablet contains brivaracetam, which works by binding to a specific protein in the brain called synaptic vesicle protein 2A (SV2A). Inside the brain, nerve cells communicate through electrical signals. During a seizure, these signals become hyperactive, disorganised, and fire too quickly. By attaching to this protein, Britzilam SR 100 Tablet helps slow down the release of chemical messengers that trigger abnormal electrical storms, restoring a calmer and more stable state in your brain.
