HYDROCORTISONE AND ACETIC ACID vs TRIANEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Triamcinolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.

Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Terminal elimination half-life is 12 hours (range 10–14 hours) in healthy adults; prolonged to 24–30 hours in severe hepatic impairment.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
Renal excretion of unchanged drug accounts for 70% of elimination; biliary/fecal elimination accounts for 20%; 10% metabolized to inactive metabolites.
