EMFLAZA vs RAYOS
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.
Synthetic glucocorticoid with anti-inflammatory, immunosuppressive, and metabolic effects; binds to glucocorticoid receptor, modulating gene expression and inhibiting phospholipase A2, cytokine production, and immune cell activity.
0.6 mg/kg orally once daily (maximum 60 mg/day); titrate to lowest effective dose based on clinical response.
Initial adult dose 5-60 mg orally once daily, adjusted based on disease severity and response. Typically administered as a single dose in the morning with food.

6.2 hours (range 4.5–8.1 h) in healthy adults; prolonged in hepatic impairment.
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Renal excretion of inactive metabolites; less than 5% excreted as unchanged drug in urine. Biliary/fecal elimination accounts for <1%.
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
