Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DEXAIR (dexamethasone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (e.g., cytokines, prostaglandins). It also inhibits leukocyte infiltration and reduces capillary permeability.
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.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
0.75 mg orally once daily, typically as part of a tapering regimen for anti-inflammatory or immunosuppressive effects.
