DELTA-CORTEF vs HYDROCORTISONE AND ACETIC ACID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
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.
Prednisolone (DELTA-CORTEF) typical adult dose: 5-60 mg orally once daily or in divided doses, depending on condition. For acute exacerbations: 20-60 mg orally daily. Route: oral. Frequency: once daily or divided.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.

Terminal elimination half-life: 1.5-2.5 hours (mean ~2 hours) for prednisolone; clinical context: short-acting glucocorticoid, requires multiple daily dosing for sustained anti-inflammatory effect, adrenocortical suppression lasts approximately 1.25-1.5 days after discontinuation.
Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Renal: approximately 80-90% as unchanged drug and metabolites (primarily 20β-dihydrocortisone and other inactive conjugates); biliary/fecal: <10%.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
