Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic corticosteroid with potent glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
Corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced synthesis of prostaglandins and leukotrienes. This results in anti-inflammatory, antipruritic, and vasoconstrictive effects.
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.
Apply a thin layer to affected area twice daily. Max 60 g/week.

Terminal elimination half-life is 2.5–3.5 hours; clinically, this short half-life requires multiple daily dosing for sustained effects.
Terminal elimination half-life: 1-2 hours (topical use); 3-4 hours (systemic absorption after topical application to large areas or occluded skin). Clinical context: short half-life allows once- or twice-daily dosing.
Primarily renal (80% as metabolites, 20% unchanged); minor biliary/fecal (<5%).
Renal: <1% as unchanged drug; biliary/fecal: minimal; primarily hepatic metabolism with metabolites excreted renally.
