Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid agonist; activates glucocorticoid receptors, leading to inhibition of inflammatory mediators (e.g., cytokines, prostaglandins) and suppression of immune cell migration and activation in nasal mucosa.
Corticosteroid that inhibits inflammatory mediators (e.g., prostaglandins, leukotrienes) and reduces nasal mucosa inflammation.
Beclomethasone dipropionate aqueous nasal spray: 1-2 sprays (42-84 mcg/spray) in each nostril twice daily. Total daily dose: 168-336 mcg.
2 sprays (64 mcg) per nostril once daily, or 1 spray (32 mcg) per nostril twice daily; intranasal use.

Terminal elimination half-life of beclomethasone dipropionate (BDP) is approximately 6.5 hours after intranasal administration; active metabolite beclomethasone-17-monopropionate (17-BMP) has a half-life of about 2.7 hours; clinical context: intranasal half-life supports once- or twice-daily dosing.
Terminal elimination half-life is 2.0–3.6 hours in adults, allowing twice-daily dosing.
Renal: <10% as unchanged drug; biliary/fecal: predominant route, with metabolites excreted in bile and feces; total elimination: >90% as metabolites via feces.
Budesonide (active ingredient) is primarily eliminated via hepatic metabolism (CYP3A4) with metabolites excreted in urine (60%) and feces (40%). Unchanged drug in urine is less than 10%.
