DEXONE 1.5 vs HYDROCORTISONE AND ACETIC ACID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
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.
1.5 mg orally once daily
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.

Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
