HYDROCORTISONE AND ACETIC ACID vs STERANE
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.
Sterane (prednisolone) is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.

Plasma t1/2: 1.5-2 hours; biological t1/2: 8-12 hours (based on HPA axis suppression).
Terminal elimination half-life is approximately 2.5 hours (range 2-3 hours) in adults with normal renal function; clinically, this supports twice-daily dosing
Renal: ~60-70% as metabolites; biliary/fecal: ~10-15%; unchanged drug: <5%.
