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 glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, inhibition of phospholipase A2, and reduction of prostaglandin and leukotriene synthesis.
0.5 mg orally once daily, with gradual taper to lowest effective dose
Initial adult dose: 5-60 mg orally, intramuscularly, or intravenously daily, divided into 2-4 doses; maintenance: 2.5-15 mg daily.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal half-life: 2.1-3.5 hours in adults; prolonged in hepatic impairment (up to 12 hours) or with concurrent estrogen use.
