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.
Glucocorticoid receptor agonist; suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene transcription.
0.5 mg orally once daily, with gradual taper to lowest effective dose
Oral: Initial dose 50-100 mg twice daily; maintenance 25-50 mg twice daily. Maximum 200 mg/day.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal elimination half-life: 2.6-3.8 hours. Clinical context: Short half-life requires multiple daily dosing; no significant accumulation with regular dosing.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Renal: 20-30% as unchanged drug; biliary/fecal: 70-80% as metabolites and unchanged drug.
