Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a potent glucocorticoid that binds to glucocorticoid receptors, modulating gene expression to inhibit pro-inflammatory cytokines (e.g., IL-1, IL-6, TNF-α) and reduce inflammation, immune response, and adrenal function.
Synthetic glucocorticoid with anti-inflammatory, immunosuppressive, and metabolic effects; binds to glucocorticoid receptor, modulating gene expression and inhibiting phospholipase A2, cytokine production, and immune cell activity.
0.75 mg orally once daily, typically as part of a tapering regimen for anti-inflammatory or immunosuppressive effects.
Initial adult dose 5-60 mg orally once daily, adjusted based on disease severity and response. Typically administered as a single dose in the morning with food.
