Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, leading to altered gene expression and suppression of inflammatory mediators, immune cells, and cytokine production.
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.
5-60 mg orally once daily or divided twice daily; dose individualized based on condition and response.
0.5 mg orally once daily, with gradual taper to lowest effective dose

The terminal elimination half-life of prednisolone (active form) is 2.1–3.5 hours. In clinical context, this short half-life supports once-daily to twice-daily dosing for anti-inflammatory effects, but adrenal suppression can persist longer due to receptor binding.
3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Prednisone is a prodrug converted to prednisolone. Prednisolone is metabolized primarily in the liver. Renal excretion of unchanged drug is negligible (<1%). Metabolites are excreted renally (approximately 80% as glucuronides and sulfates) and to a small extent in feces (<5%). Biliary excretion is minimal.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
