DIAZEPAM INTENSOL vs VALIUM
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.
Benzodiazepine that enhances the effect of GABA at GABA-A receptors, increasing chloride ion conductance and producing 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.
Oral: 2-10 mg 2-4 times daily. IV/IM: 5-10 mg, repeat in 3-4 hours if needed; max 30 mg in 8 hours.

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 of diazepam: 20–50 hours; active metabolite desmethyldiazepam half-life: 36–200 hours (accumulates with chronic dosing, prolonging clinical effects).
Renal excretion of metabolites (primarily glucuronide conjugates) accounts for ~70% of elimination; fecal excretion accounts for ~10%; unchanged drug in urine is <1%.
Renal: <1% unchanged; hepatic metabolism to active metabolites (desmethyldiazepam, temazepam, oxazepam); metabolites excreted renally as glucuronides. Fecal: minor.
