KERLEDEX vs XHANCE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Kerledex is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane.
XHANCE (fluticasone propionate) is an anti-inflammatory corticosteroid that inhibits multiple inflammatory cell types and mediators (e.g., histamine, leukotrienes, cytokines) involved in nasal and sinus inflammation. It reduces nasal polyp size and nasal congestion.
Intravenous: 500 mg every 6 hours; Oral: 250 mg every 8 hours.
1 spray (93 mcg fluticasone propionate) per nostril twice daily (total daily dose 372 mcg). Intranasal route.

Terminal half-life 12 hours (range 10–14) in normal renal function; extended to 30–50 hours in severe renal impairment (CrCl <30 mL/min); 6–8 hours in hepatic cirrhosis.
Terminal half-life is approximately 2-3 hours; short half-life supports twice-daily dosing for sustained local effect.
Renal: 70% unchanged; fecal/biliary: 20% as metabolites; 10% as minor metabolites. Total renal clearance 180 mL/min, active tubular secretion accounts for 60% of renal elimination.
Primarily hepatic metabolism; renal excretion of metabolites accounts for <10% of the dose as unchanged drug; fecal excretion is minimal.
