Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene transcription. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis; suppresses inflammatory cytokine production; and causes vasoconstriction and immunosuppression.
Corticosteroid with high glucocorticoid receptor affinity; reduces inflammation by inhibiting phospholipase A2, decreasing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Hydrocortisone 100-500 mg IV/IM every 2-6 hours as needed for acute adrenal insufficiency or severe inflammation. Maintenance: 20-30 mg/day PO divided every 8-12 hours.
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.

1.5–2.5 hours (terminal half-life). In clinical context, the biological half-life (duration of HPA suppression) is longer (8–12 hours) due to tissue binding and active metabolites.
Terminal elimination half-life is 2.2-4.3 hours; clinical context: supports twice-daily dosing in ophthalmic use, with minimal systemic accumulation.
Renal: predominantly as conjugated metabolites and a small fraction of unchanged drug. Biliary/fecal: minor, <5%. Total renal clearance accounts for >95% of elimination.
Primarily hepatic metabolism; metabolites excreted in urine (approximately 80% as inactive metabolites) and feces (15-20%). Less than 1% excreted unchanged in urine.
