Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor and modulating gene expression to produce anti-inflammatory and immunosuppressive effects. It also suppresses adrenal function by inhibiting ACTH secretion.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (cytokines, prostaglandins, leukotrienes).
0.75-9 mg/day orally in divided doses every 6-12 hours; or 0.5-9 mg/day IM/IV in divided doses every 12 hours for acute conditions; for cerebral edema, IV loading dose of 10 mg followed by 4 mg IM/IV every 6 hours.
5-60 mg/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.

Terminal half-life: 3-4 hours (plasma); biological half-life: 36-54 hours (due to intracellular receptor binding); clinical context: duration of HPA axis suppression longer than plasma half-life
2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
Renal (65-80% as 17-hydroxycorticosteroids and 20-hydroxycorticosteroids after hepatic metabolism); biliary/fecal (minor, <10%)
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
