FLONASE vs TARPEYO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a corticosteroid that binds to glucocorticoid receptors, inhibiting inflammatory mediators such as cytokines, leukotrienes, and prostaglandins, thereby reducing nasal inflammation.
TARPEYO (budesonide) is a corticosteroid with anti-inflammatory activity. It acts by binding to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines and immune cell activation, thereby reducing proteinuria in IgA nephropathy.
2 sprays (50 mcg/spray) per nostril once daily; may increase to 2 sprays per nostril twice daily if needed. Intranasal route.
16 mg/kg intravenously once daily on Days 1-5 of each 28-day cycle.

Terminal elimination half-life is approximately 3 hours (range 2-4 hours). This short half-life supports twice-daily dosing for systemic effects; however, intranasal administration achieves local therapeutic concentrations with minimal systemic exposure.
Terminal elimination half-life is approximately 27.3 hours (range 21-36 hours) in patients with IgA nephropathy. This supports once-weekly subcutaneous dosing without dose adjustment over the dosing interval.
Primarily hepatic metabolism (CYP3A4), with metabolites excreted in feces (approximately 87-90%) and urine (<5% unchanged). Less than 5% of a dose is excreted renally as unchanged drug.
Primarily hepatic metabolism, with <1% excreted unchanged in urine and <1% in feces. Elimination is predominantly via biliary excretion of metabolites into feces, accounting for >90% of total clearance.
