Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist at glucocorticoid receptors, modulating gene expression to suppress inflammation, immune response, and adrenal function.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (cytokines, prostaglandins, leukotrienes).
0.5-9 mg/day orally in divided doses every 6-12 hours; intravenously or intramuscularly as dexamethasone sodium phosphate; typical anti-inflammatory dose 0.75-9 mg/day. For cerebral edema: IV loading dose 10 mg, then 4 mg every 6 hours. For COVID-19: 6 mg IV or orally once daily for up to 10 days.
5-60 mg/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.

Terminal elimination half-life: 3-5 hours in adults; slightly prolonged in neonates (approximately 12-24 hours) and patients with hepatic impairment. Clinical context: Duration of HPA axis suppression may exceed the presence of measurable drug; single dose typically suppresses cortisol for 24-36 hours.
2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
Renal (primarily as glucuronide and sulfate conjugates) and biliary/fecal (minor). Approximately 65-80% of a dose is excreted in urine within 24 hours as 20-beta-dihydrodexamethasone (inactive) and conjugated metabolites; about 10-15% appears in feces. Less than 5% is excreted unchanged.
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
