HYDROCORTISONE AND ACETIC ACID vs TRIATEX
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.
TRIATEX (methotrexate) inhibits dihydrofolate reductase, blocking tetrahydrofolate synthesis and thereby interfering with DNA synthesis, repair, and cellular replication. It also has immunomodulatory and anti-inflammatory effects through adenosine-mediated pathways.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.
Triatex (trianterene/hydrochlorothiazide) 37.5 mg/25 mg or 75 mg/50 mg orally once daily; may increase to maximum of 2 capsules daily.

Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Terminal elimination half-life is 8-12 hours (mean 10 hours) in adults with normal renal function; prolonged to 20-40 hours in moderate-severe renal impairment (CrCl <30 mL/min).
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
Primarily renal excretion (80-90% as unchanged drug via glomerular filtration and active tubular secretion) with 5-10% fecal elimination.
