DEXACORT vs PEDIAPRED
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist that modulates gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Prednisolone is a glucocorticoid receptor agonist that binds to the intracellular glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production (e.g., IL-1, IL-6, TNF-alpha). It also suppresses immune responses by reducing lymphocyte proliferation and activity.
Oral: 0.75-9 mg/day in divided doses; IV: 0.5-9 mg/day every 6-12 hours; IM: 4-20 mg every 2 weeks.
Oral: 5-60 mg/day as a single dose or divided doses; adjust based on condition and response.

Plasma terminal elimination half-life is 2.8-3.5 hours in adults, but the biological half-life (duration of HPA axis suppression) is 24-36 hours due to prolonged receptor occupancy
2.5–3.5 hours (terminal) in children; clinical context: requires multiple daily doses for sustained effect.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
Renal: ~80% as metabolites (mainly glucuronides and sulfates) and <5% unchanged; fecal: ~15%.
