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 subsequent anti-inflammatory and immunosuppressive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses cytokine production.
0.5 mg orally once daily, with gradual taper to lowest effective dose
10-60 mg orally once daily or divided twice daily; maximum 60 mg/day.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal elimination half-life: 2-3 hours (after IV/IM/oral). Clinically, anti-inflammatory effects persist beyond plasma half-life due to glucocorticoid receptor-mediated gene transcription effects.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Primarily renal (80-90% as inactive glucuronide and sulfate conjugates; less than 10% as unchanged drug). Biliary/fecal excretion accounts for about 5%.
