NASACORT HFA vs PULMICORT
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.
Glucocorticoid receptor agonist; inhibits inflammatory mediators, reduces airway edema and mucus secretion.
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: 200-800 mcg twice daily for maintenance; maximum 1600 mcg/day. Nebulization: 0.5-1 mg twice daily.

Terminal elimination half-life is approximately 3.5 hours following intranasal administration, reflecting slow systemic absorption and prolonged local retention.
The terminal elimination half-life of budesonide is approximately 2.0 to 3.6 hours in adults, with a mean of about 2.8 hours. This short half-life is consistent with its rapid clearance and lack of significant accumulation with once- or twice-daily dosing.
Renal (approximately 40% as metabolites), fecal (approximately 60% as metabolites and parent drug)
Budesonide is primarily metabolized in the liver via CYP3A4 to inactive metabolites. Approximately 60% of the dose is excreted in urine as metabolites, and 40% in feces. Less than 10% of unchanged drug is excreted renally.
