Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine; enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and inhibition.
Levetiracetam is a racetam anticonvulsant that binds to synaptic vesicle glycoprotein 2A (SV2A), reducing neurotransmitter release and neuronal excitability. It also inhibits N-type calcium channels and modulates GABAergic and glutamatergic transmission.
0.5 mg to 2 mg orally twice daily for anxiety; 0.5 mg to 1 mg orally three times daily for panic disorder. Maximum dose: 4 mg/day for panic disorder.
50 mg orally once daily, preferably in the evening. Maximum dose 100 mg/day.

Terminal half-life 30-40 hours (range 19-60 h) in adults; accumulation occurs with repeated dosing, steady-state reached in 5-7 days.
Terminal elimination half-life is 6-8 hours in healthy adults; prolonged in renal impairment (up to 16 hours in severe impairment).
Renal (60-80% as metabolites, mainly glucuronide conjugates; <2% as unchanged drug). Biliary/fecal excretion accounts for ~10-20%.
Renal excretion of unchanged drug accounts for approximately 70% of elimination; fecal excretion accounts for approximately 30%, primarily as metabolites.
