Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Stabilizes neuronal membranes by blocking voltage-gated sodium channels, inhibiting repetitive firing of action potentials. Also enhances GABAergic activity.
Stabilizes neuronal membranes by blocking voltage-gated sodium channels and inhibiting the release of excitatory neurotransmitters, particularly glutamate and aspartate.
Initial dose 200 mg orally twice daily, increase by 200 mg/day at weekly intervals; maintenance 800-1200 mg/day in 2 divided doses extended-release capsules.
