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 (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
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.
0.5 mg orally once daily, with gradual taper to lowest effective dose
5-60 mg orally once daily or divided as 5-15 mg every 4-12 hours; adjust based on response and condition.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
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: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Renal: approximately 60-80% as unchanged drug and conjugated metabolites; biliary/fecal: minor (5-10%)
