DEXAMETHASONE vs PENECORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist at glucocorticoid receptors, leading to altered gene expression and suppression of inflammatory mediators.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
0.5-24 mg/day oral, IV, IM in 2-4 divided doses; anti-inflammatory: 0.75-9 mg/day; multiple myeloma: 40 mg oral/IV once daily on days 1-4, 9-12, 17-20 every 28 days.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.
