PARACORT vs RAYOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Paracort is a corticosteroid that acts by binding to glucocorticoid receptors, leading to modulation of gene expression and suppression of inflammatory mediators such as cytokines and prostaglandins.
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.
Prednisone 5-60 mg orally once daily; initial dose 5-15 mg daily; for acute conditions, up to 60 mg daily tapered over 2-3 weeks.
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.

Terminal elimination half-life is 3.5 hours (range 2.5–4.5 hours) in adults with normal renal function; prolonged to up to 10–15 hours in severe renal impairment (CrCl <30 mL/min).
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Renal elimination of unchanged drug accounts for approximately 70% of the dose; biliary/fecal excretion accounts for 20%; the remainder is metabolized and excreted as inactive metabolites.
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
