Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective enhancement of slow inactivation of voltage-gated sodium channels, stabilizing neuronal membranes and inhibiting excitatory neurotransmitter release.
Increases seizure threshold by modulating voltage-gated sodium channels and enhancing GABA-ergic inhibition.
Initial: 50 mg orally once daily; titrate at weekly intervals by 50 mg twice daily increments to maintenance dose of 200 mg twice daily (400 mg/day). Maximum: 400 mg twice daily (800 mg/day).
300-600 mg orally three times daily; titrate to seizure control.

Terminal elimination half-life ranges from 20 to 48 hours (mean ~32 hours). Steady-state achieved within 5-7 days.
16-24 hours (trimethadione); dimethadione (active metabolite) has a half-life of ~6-12 days, leading to drug accumulation.
Primarily eliminated by hepatic metabolism, with approximately 95% excreted as metabolites in urine and <2% as unchanged drug. Fecal excretion accounts for about 5%.
Renal: ~70% as unchanged drug and metabolites (including dimethadione); biliary/fecal: minimal (<10%).
