PENECORT vs RAYOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, 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.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 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.
