Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with high glucocorticoid receptor affinity; reduces inflammation by inhibiting phospholipase A2, decreasing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Synthetic corticosteroid with potent glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
0.5% ophthalmic suspension: 1-2 drops into affected eye(s) four times daily. In severe cases, may be increased to 1-2 drops every hour during the first week, then taper.
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.

Terminal elimination half-life is 2.2-4.3 hours; clinical context: supports twice-daily dosing in ophthalmic use, with minimal systemic accumulation.
Terminal elimination half-life is 2.5–3.5 hours; clinically, this short half-life requires multiple daily dosing for sustained effects.
Primarily hepatic metabolism; metabolites excreted in urine (approximately 80% as inactive metabolites) and feces (15-20%). Less than 1% excreted unchanged in urine.
Primarily renal (80% as metabolites, 20% unchanged); minor biliary/fecal (<5%).
