DIAZEPAM vs VALIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Benzodiazepine that enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and inhibition.
Benzodiazepine that enhances the effect of GABA at GABA-A receptors, increasing chloride ion conductance and producing neuronal hyperpolarization.
Anxiety: 2-10 mg PO BID-QID; Sedation/Muscle spasm: 5-10 mg IV/IM q3-4h PRN; Status epilepticus: 0.15-0.2 mg/kg IV (max 10 mg) q10-15 min PRN.
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 half-life 30-56 hours (range 20-70 hours) in adults; prolonged in elderly (up to 100 hours), neonates (up to 100 hours), and cirrhosis (up to 100+ hours).
Clinical Note
moderateDiazepam + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Diazepam is combined with Fluticasone propionate."

Clinical Note
moderateDiazepam + Tenofovir disoproxil
"The metabolism of Tenofovir disoproxil can be decreased when combined with Diazepam."
Clinical Note
moderateTerminal elimination half-life of diazepam: 20–50 hours; active metabolite desmethyldiazepam half-life: 36–200 hours (accumulates with chronic dosing, prolonging clinical effects).
Renal (70-80% as metabolites, primarily glucuronide conjugates; <5% unchanged), fecal (10-20% as metabolites), biliary (minor).
Renal: <1% unchanged; hepatic metabolism to active metabolites (desmethyldiazepam, temazepam, oxazepam); metabolites excreted renally as glucuronides. Fecal: minor.
