Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive actions. Suppresses cytokine production, inhibits phospholipase A2, and reduces prostaglandin and leukotriene synthesis.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to increased lipocortin synthesis, inhibition of phospholipase A2, decreased arachidonic acid release, and reduced prostaglandin and leukotriene production; it also suppresses cytokine expression and immune cell migration. Acetic acid is a weak acid that lowers local pH, inhibiting bacterial and fungal growth and disrupting microbial cell membranes.
0.1-0.2 mg/kg intravenously once.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.

Terminal elimination half-life is 2-4 hours. Clinical context: Short half-life requires frequent dosing for sustained effect; accumulation possible in renal impairment.
Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Renal excretion of unchanged drug and metabolites accounts for approximately 70-80% of elimination, with biliary/fecal excretion contributing 20-30%.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
