Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that potentiates GABA-A receptor activity by binding to the benzodiazepine site, increasing chloride ion conductance and neuronal 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.
2 to 10 mg orally 2 to 4 times daily, as needed for anxiety or muscle spasm; 10 mg orally before procedures for sedation. Maximum 40 mg/day.
50 mg orally once daily, preferably in the evening. Maximum dose 100 mg/day.

Terminal elimination half-life is 20–50 hours (mean ~30 hours) in adults, with significant interindividual variability; prolonged in elderly, hepatic impairment, and neonates (up to 100 hours).
Terminal elimination half-life is 6-8 hours in healthy adults; prolonged in renal impairment (up to 16 hours in severe impairment).
Renal excretion of metabolites (primarily glucuronide conjugates) accounts for ~70% of elimination; fecal excretion accounts for ~10%; unchanged drug in urine is <1%.
Renal excretion of unchanged drug accounts for approximately 70% of elimination; fecal excretion accounts for approximately 30%, primarily as metabolites.
