DEXONE 4 vs LIQUID PRED
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist, binding to glucocorticoid response elements to modulate gene transcription, resulting in anti-inflammatory, immunosuppressive, anti-allergic, and anti-shock effects.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (cytokines, prostaglandins, leukotrienes).
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.
5-60 mg/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.

Terminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
Renal excretion of metabolites (<5% unchanged drug); minor biliary/fecal elimination (<1%)
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
