Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist at glucocorticoid receptors, leading to altered gene expression and suppression of inflammatory mediators.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
0.5-24 mg/day oral, IV, IM in 2-4 divided doses; anti-inflammatory: 0.75-9 mg/day; multiple myeloma: 40 mg oral/IV once daily on days 1-4, 9-12, 17-20 every 28 days.

Terminal elimination half-life 3-4 hours; clinically, duration of HPA suppression may exceed 24 hours due to prolonged receptor binding.

Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
Primarily renal (65-80% as unchanged drug); minor biliary/fecal (<10%).
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
