RAYOS vs SERVISONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
SERVISONE is a corticosteroid that exerts anti-inflammatory and immunosuppressive effects by binding to glucocorticoid receptors, modulating gene transcription, and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
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.
10-20 mg orally once daily in the morning; higher doses up to 40 mg daily for severe cases.

2-3 hours (terminal); prolonged in hepatic impairment; circadian-timed formulation intended for once-daily morning dosing.
Terminal elimination half-life is 3-4 hours. Clinically, this supports twice-daily dosing for sustained effect.
Renal: ~80% as inactive metabolites; fecal: ~5%; biliary: small amount.
Renal (70-80% as metabolites, 5-10% unchanged); fecal/biliary (15-20%)
