🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by increasing the concentration of gamma-aminobutyric acid (GABA) in the brain. GABA is an inhibitory neurotransmitter that reduces the excessive electrical activity of nerve cells that can lead to seizures and mood swings. It achieves this by inhibiting the enzymes that break down GABA and by enhancing the release of GABA from nerve terminals. Additionally, it may block voltage-gated sodium channels, which further stabilizes neuronal membranes and prevents the spread of abnormal electrical signals. The overall effect is a calming influence on the central nervous system, which helps to control seizures and stabilize mood.
