DELTA-CORTEF vs RAYOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid; binds to glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
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.
Prednisolone (DELTA-CORTEF) typical adult dose: 5-60 mg orally once daily or in divided doses, depending on condition. For acute exacerbations: 20-60 mg orally daily. Route: oral. Frequency: once daily or divided.
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: 1.5-2.5 hours (mean ~2 hours) for prednisolone; clinical context: short-acting glucocorticoid, requires multiple daily dosing for sustained anti-inflammatory effect, adrenocortical suppression lasts approximately 1.25-1.5 days after discontinuation.
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Renal: approximately 80-90% as unchanged drug and metabolites (primarily 20β-dihydrocortisone and other inactive conjugates); biliary/fecal: <10%.
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
