DEFLAZACORT vs XHANCE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Deflazacort is a glucocorticoid prodrug that is metabolized to its active form, 21-desacetyldeflazacort. It binds to glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating cytokine production.
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.
6-90 mg orally once daily; initial dose typically 6-30 mg/day, maintenance as lowest effective dose; taper gradually upon discontinuation.
1 spray (93 mcg fluticasone propionate) per nostril twice daily (total daily dose 372 mcg). Intranasal route.

moderateDeflazacort + Gatifloxacin
"The risk or severity of adverse effects can be increased when Deflazacort is combined with Gatifloxacin."

Terminal half-life of the active metabolite Δ6-deflazacort is 1.1–1.9 hours; parent drug half-life is approximately 1–2 hours. Clinical glucocorticoid effect persists for 12–24 hours due to receptor binding.
Terminal half-life is approximately 2-3 hours; short half-life supports twice-daily dosing for sustained local effect.
Renal (approximately 70% as metabolites, <5% unchanged); biliary/fecal (approximately 30%)
Primarily hepatic metabolism; renal excretion of metabolites accounts for <10% of the dose as unchanged drug; fecal excretion is minimal.
