Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone sodium phosphate is a glucocorticoid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
Sterane (prednisolone) is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.
4-20 mg IV or IM every 4-6 hours; for cerebral edema: 10 mg IV followed by 4 mg IM/IV every 6 hours; for shock: 20 mg IV initially then 2-6 mg/kg IV bolus or 40 mg IV every 2-6 hours as needed.
100 mg orally every 12 hours

Terminal elimination half-life is 3-4 hours in adults; however, the duration of action extends beyond the plasma half-life due to intracellular receptor-mediated effects.
Terminal elimination half-life is approximately 2.5 hours (range 2-3 hours) in adults with normal renal function; clinically, this supports twice-daily dosing
Renal excretion of unchanged drug and metabolites accounts for approximately 60-70% of elimination; biliary/fecal excretion accounts for 30-40%.
Renal (approximately 70% as unchanged drug and glucuronide conjugate), biliary/fecal (approximately 30%)
