METHYLPREDNISOLONE vs PENECORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; inhibits phospholipase A2, decreases prostaglandin and leukotriene synthesis; suppresses cytokine production and immune cell activity.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
4-48 mg/day orally in divided doses; 10-40 mg IV/IM bolus, then 10-40 mg IV q4-6h; high-dose IV pulse: 1 g/day for 3 days.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.

Plasma: 2.5-3.5 hours; biological half-life (tissue): 18-36 hours due to glucocorticoid receptor-mediated effects; clinical context: anti-inflammatory effects persist beyond plasma clearance
