METICORTELONE vs RAYOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with glucocorticoid and mineralocorticoid activity; binds to 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.
Prednisolone: 5-60 mg orally once daily or divided twice daily; methylprednisolone: 4-48 mg orally once daily or divided twice daily. Dose and duration vary by indication.
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: 3.0-3.5 hours; clinical context: requires multiple daily doses for sustained effect; biological half-life (duration of HPA suppression) longer (~24-36 hours) due to intracellular activity
2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Renal: <5% unchanged; hepatic metabolism to inactive metabolites, primarily conjugated and excreted in urine; <2% fecal
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
