HYDROCORTISONE AND ACETIC ACID vs KERLEDEX
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.
Kerledex is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane.
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 half-life 12 hours (range 10–14) in normal renal function; extended to 30–50 hours in severe renal impairment (CrCl <30 mL/min); 6–8 hours in hepatic cirrhosis.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
Renal: 70% unchanged; fecal/biliary: 20% as metabolites; 10% as minor metabolites. Total renal clearance 180 mL/min, active tubular secretion accounts for 60% of renal elimination.
