HYDROCORTISONE AND ACETIC ACID vs TRYMEX
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.
TRYMEX is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity by blocking the reuptake of serotonin at the presynaptic neuron, enhancing neurotransmission in the central nervous system.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.
Adults: 500 mg orally twice daily or 1 g intravenously once daily.

Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Terminal elimination half-life is 12-15 hours in adults with normal renal function; extends to 30-40 hours in severe renal impairment (CrCl <30 mL/min), requiring dose adjustment.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
Renal excretion of unchanged drug accounts for 60-70% of dose; biliary/fecal elimination contributes 20-30%, with <5% as metabolites.
