HYDROCORTISONE AND ACETIC ACID vs SERVISONE
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.
SERVISONE is a corticosteroid that exerts anti-inflammatory and immunosuppressive effects by binding to glucocorticoid receptors, modulating gene transcription, and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.
10-20 mg orally once daily in the morning; higher doses up to 40 mg daily for severe cases.

Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Terminal elimination half-life is 3-4 hours. Clinically, this supports twice-daily dosing for sustained effect.
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
