How Topiramate Works

The exact way Topiramate works is not fully understood, but it is known to:

• Reduce abnormal nerve activity in the brain.
• Enhance the activity of gamma-aminobutyric acid (GABA), a calming neurotransmitter.
• Block certain excitatory signals involved in seizures.
• Reduce excessive nerve firing associated with migraine attacks.

These actions help stabilize brain activity and reduce the likelihood of seizures and migraines.
