DEXACEN-4 vs FLUDROCORTISONE ACETATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that binds to the glucocorticoid receptor, leading to increased transcription of anti-inflammatory proteins and suppression of pro-inflammatory mediators.
Mineralocorticoid receptor agonist; promotes sodium reabsorption and potassium excretion in renal distal tubules, increasing extracellular fluid volume. Also has glucocorticoid activity.
Dexamethasone 4 mg orally or intravenously every 6-8 hours; typical adult dose is 4-20 mg/day in divided doses, depending on condition.
0.1 mg orally once daily, range 0.05-0.2 mg/day

3-4 hours; prolonged to 6-8 hours in renal impairment (CrCl <30 mL/min)
Terminal elimination half-life is 3.5 hours (range 2–5 h); clinical effect duration exceeds half-life due to mineralocorticoid receptor binding.
Renal: 65-80% as unchanged drug; Biliary: 10-15% as metabolites; Fecal: <5%
Renal (80%) as inactive metabolites; less than 5% unchanged; minor biliary/fecal elimination.
