Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, immune responses, and adrenal function.
1.5 mg orally once daily
5-60 mg orally once daily or divided as 5-15 mg every 4-12 hours; adjust based on response and condition.

Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
4-5 hours (terminal); prolonged in renal impairment (up to 12+ hours in anuria) and hepatic dysfunction; clinical context: dosing interval adjustment in severe renal failure
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
Renal: approximately 60-80% as unchanged drug and conjugated metabolites; biliary/fecal: minor (5-10%)
