DEXONE 4 vs FLUDROCORTISONE 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.
Mineralocorticoid receptor agonist; promotes sodium reabsorption and potassium excretion in renal distal tubules, increasing extracellular fluid volume. Also has glucocorticoid activity.
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.
0.1 mg orally once daily, range 0.05-0.2 mg/day

Terminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
Terminal elimination half-life is 3.5 hours (range 2–5 h); clinical effect duration exceeds half-life due to mineralocorticoid receptor binding.
Renal excretion of metabolites (<5% unchanged drug); minor biliary/fecal elimination (<1%)
Renal (80%) as inactive metabolites; less than 5% unchanged; minor biliary/fecal elimination.
