EMFLAZA vs METICORTEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist at glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response.
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.
0.6 mg/kg orally once daily (maximum 60 mg/day); titrate to lowest effective dose based on clinical response.
5-60 mg orally once daily, depending on condition; for acute exacerbations, up to 250 mg IV every 4-6 hours.

6.2 hours (range 4.5–8.1 h) in healthy adults; prolonged in hepatic impairment.
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.
Renal excretion of inactive metabolites; less than 5% excreted as unchanged drug in urine. Biliary/fecal elimination accounts for <1%.
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.
