DIAZEPAM INTENSOL vs ZAXOPAM
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.
Zaxopam is a benzodiazepine that enhances GABA-A receptor activity by binding to the benzodiazepine site, increasing chloride ion influx and causing neuronal hyperpolarization.
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.
10 mg orally twice daily, titrated to a maximum of 30 mg twice daily based on response and tolerability; oral route.

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 12-15 hours, allowing for once-daily dosing in most patients.
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 accounts for approximately 80% of the administered dose, predominantly as conjugated metabolites; biliary/fecal excretion accounts for the remaining 20%.
