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.
Synthetic corticosteroid with potent glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
0.5 mg orally once daily, with gradual taper to lowest effective dose
100 mg intravenously every 8 hours for 24 hours, then 50 mg intravenously every 8 hours for 48 hours, followed by 25 mg intravenously every 8 hours for 72 hours.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal elimination half-life is 2.5–3.5 hours; clinically, this short half-life requires multiple daily dosing for sustained effects.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Primarily renal (80% as metabolites, 20% unchanged); minor biliary/fecal (<5%).
