DEXONE 4 vs PREDNISOLONE ACETATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist, binding to glucocorticoid response elements to modulate gene transcription, resulting in anti-inflammatory, immunosuppressive, anti-allergic, and anti-shock effects.
Glucocorticoid receptor agonist; modulates gene expression to inhibit pro-inflammatory cytokines, phospholipase A2, and NF-κB; suppresses immune response and inflammation.
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.
5-60 mg orally once daily or divided every 12-24 hours; dose depends on condition and severity. For acute exacerbations, 200-400 mg intramuscularly once.

Terminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
Terminal elimination half-life: 2-4 hours (plasma); biological (tissue) half-life: 18-36 hours due to prolonged glucocorticoid receptor-mediated effects. Half-life prolonged in hepatic disease.
Renal excretion of metabolites (<5% unchanged drug); minor biliary/fecal elimination (<1%)
Renal (fraction excreted unchanged: <1%); primarily hepatic metabolism to inactive glucuronide and sulfate conjugates eliminated renally and fecally. After oral administration, 12-15% of dose recovered in bile/feces as metabolites.
