Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
Mineralocorticoid receptor agonist; promotes sodium reabsorption and potassium excretion in renal distal tubules, increasing extracellular fluid volume. Also has glucocorticoid activity.
0.5 mg orally once daily, with gradual taper to lowest effective dose
0.1 mg orally once daily, range 0.05-0.2 mg/day

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal elimination half-life is 3.5 hours (range 2–5 h); clinical effect duration exceeds half-life due to mineralocorticoid receptor binding.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Renal (80%) as inactive metabolites; less than 5% unchanged; minor biliary/fecal elimination.
