Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
Corticosteroid with high glucocorticoid receptor affinity; reduces inflammation by inhibiting phospholipase A2, decreasing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
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.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
Terminal elimination half-life is 2.2-4.3 hours; clinical context: supports twice-daily dosing in ophthalmic use, with minimal systemic accumulation.
Primarily hepatic metabolism with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
Primarily hepatic metabolism; metabolites excreted in urine (approximately 80% as inactive metabolites) and feces (15-20%). Less than 1% excreted unchanged in urine.
