Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to glucocorticoid receptors, inhibiting inflammatory mediators (e.g., cytokines, prostaglandins) and reducing nasal inflammation.
Budesonide is a corticosteroid with potent anti-inflammatory effects. It inhibits multiple inflammatory cell types and mediators such as cytokines, chemokines, and adhesion molecules, reducing airway hyperresponsiveness and inflammation.
55 mcg (1 spray) per nostril once daily; may increase to 110 mcg (2 sprays) per nostril once daily if needed. Maximum 440 mcg/day total.
Inhalation: 1-2 inhalations (90-180 mcg) twice daily; maximum 720 mcg twice daily.

Terminal elimination half-life is approximately 3.5 hours following intranasal administration, reflecting slow systemic absorption and prolonged local retention.
Terminal half-life: 2.0-3.5 hours (mean 2.5 h) in adults after inhalation. Clinically, duration of effect may persist beyond pharmacokinetic half-life due to receptor binding.
Renal (approximately 40% as metabolites), fecal (approximately 60% as metabolites and parent drug)
Renal: ~60% as metabolites, fecal: ~40% as metabolites. Less than 10% unchanged in urine.
