METICORTEN vs PREDNISOLONE SODIUM PHOSPHATE
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.
Agonist of glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of pro-inflammatory cytokines, and suppression of immune cell activity.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.
Initial dose: 5-60 mg orally or intravenously once daily or divided every 12-24 hours; range 5-60 mg/day. For acute conditions, 40-60 mg once daily.

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 is 2.1–3.5 hours in adults (mean 2.6 h). Clinical context: Short half-life supports twice-daily dosing for most conditions; prolonged in hepatic impairment (up to 8 h).
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 excretion of inactive metabolites (primarily prednisolone) accounts for >80% of elimination; less than 10% excreted unchanged. Biliary/fecal excretion is negligible (<5%).
