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 and modulating gene expression to produce anti-inflammatory and immunosuppressive effects. It also suppresses adrenal function by inhibiting ACTH secretion.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to induce anti-inflammatory, antipruritic, and vasoconstrictive effects.
0.75-9 mg/day orally in divided doses every 6-12 hours; or 0.5-9 mg/day IM/IV in divided doses every 12 hours for acute conditions; for cerebral edema, IV loading dose of 10 mg followed by 4 mg IM/IV every 6 hours.
Apply a thin film to affected area twice daily. Topical use only.

Terminal half-life: 3-4 hours (plasma); biological half-life: 36-54 hours (due to intracellular receptor binding); clinical context: duration of HPA axis suppression longer than plasma half-life
Terminal elimination half-life is approximately 2-3 hours for the parent drug; 18-36 hours for the active metabolites (clinical context: duration of action is prolonged due to local tissue retention and metabolite activity)
Renal (65-80% as 17-hydroxycorticosteroids and 20-hydroxycorticosteroids after hepatic metabolism); biliary/fecal (minor, <10%)
Renal (approximately 80% as metabolites, <1% unchanged), fecal/biliary (approximately 20% as metabolites)
