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.
Beclomethasone dipropionate is a corticosteroid with anti-inflammatory activity. It binds to glucocorticoid receptors, inhibiting inflammatory mediators such as prostaglandins and leukotrienes, and reducing nasal inflammation.
0.75 mg orally once daily, typically as part of a tapering regimen for anti-inflammatory or immunosuppressive effects.
1 to 2 sprays (80 mcg/spray) per nostril once daily; maximum 2 sprays/nostril/day.

Terminal elimination half-life: 36-54 hours in adults with normal renal function; prolonged to 72-168 hours in severe renal impairment.
The terminal elimination half-life is approximately 8-10 hours in healthy adults, supporting twice-daily administration for systemic effects; however, intranasal administration results in minimal systemic absorption, and local half-life in nasal tissues is not well characterized.
Renal: ~65-80% as unchanged drug; Fecal: ~10-15% as metabolites; Minor biliary excretion.
The majority of a dose (approximately 40-50%) is excreted in feces as unchanged drug and metabolites, with about 10-15% excreted in urine as metabolites. Biliary excretion is the primary route of elimination.
