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 sodium phosphate is a corticosteroid with potent anti-inflammatory and immunosuppressant properties. It binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of pro-inflammatory cytokines, inhibition of phospholipase A2, and reduction of inflammatory mediators like prostaglandins and leukotrienes.
5-60 mg orally once daily or divided twice daily; dose individualized based on condition and response.
0.5-24 mg/day IV or IM in divided doses every 6-12 hours; acute conditions: 4-20 mg IV initially, then 2-4 mg every 4-6 hours.

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.
Terminal elimination half-life is 3-4 hours in adults; clinical context: biological effects persist >24 hours due to prolonged receptor binding.
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.
Primarily renal (approximately 65-80% as free steroid and glucuronide conjugates); minor biliary/fecal elimination (10-15%).
