METICORTEN vs PREDNISOLONE ACETATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, modulating gene expression and suppressing inflammation, immune response, and adrenal function.
Glucocorticoid receptor agonist; modulates gene expression to inhibit pro-inflammatory cytokines, phospholipase A2, and NF-κB; suppresses immune response and inflammation.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.
5-60 mg orally once daily or divided every 12-24 hours; dose depends on condition and severity. For acute exacerbations, 200-400 mg intramuscularly once.

Following oral or IV administration, the terminal elimination half-life of total prednisolone (active form) is 2.1–3.5 hours in adults with normal hepatic function. In hepatic impairment, half-life may be prolonged (up to 6–8 hours), necessitating dose adjustment.
Terminal elimination half-life: 2-4 hours (plasma); biological (tissue) half-life: 18-36 hours due to prolonged glucocorticoid receptor-mediated effects. Half-life prolonged in hepatic disease.
Primarily renal: approximately 80% as inactive metabolites (conjugated and oxidized forms) and <5% as unchanged prednisolone. Biliary/fecal excretion accounts for about 10-15% of the dose.
Renal (fraction excreted unchanged: <1%); primarily hepatic metabolism to inactive glucuronide and sulfate conjugates eliminated renally and fecally. After oral administration, 12-15% of dose recovered in bile/feces as metabolites.
