FLOVENT vs NYSTATIN AND TRIAMCINOLONE ACETONIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a synthetic corticosteroid with anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory transcription factors (e.g., NF-κB) and increased synthesis of lipocortin-1, which reduces phospholipase A2 activity and subsequent release of arachidonic acid metabolites (prostaglandins, leukotrienes). In the lungs, it decreases airway inflammation by reducing eosinophil infiltration, mast cell degranulation, and cytokine release.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that cause leakage of intracellular contents and cell death. Triamcinolone acetonide is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, immune response, and vasodilation.
Inhalation aerosol: 88-880 mcg twice daily; typical starting dose: 88 mcg twice daily. Max: 880 mcg twice daily. Oral inhalation powder: 100-1000 mcg twice daily; typical starting: 100 mcg twice daily. Max: 1000 mcg twice daily.
Apply thin layer to affected area twice daily for 2-4 weeks. Topical only.

Approximately 14.4 hours (range 7.8–24.6 hours) for the inhaled route; supports twice-daily dosing; prolonged in hepatic impairment.
Nystatin: not systemically absorbed; terminal half-life not applicable. Triamcinolone acetonide: after intramuscular injection, terminal half-life is approximately 2-5 hours; after topical application, minimal systemic absorption precludes meaningful half-life determination.
Primarily hepatic metabolism (CYP3A4) with fecal excretion of metabolites; renal excretion accounts for <5% of the dose as unchanged drug and metabolites combined.
Nystatin: primarily excreted unchanged in feces via bile (>90%); negligible renal excretion (<1%). Triamcinolone acetonide: primarily hepatically metabolized; conjugated metabolites excreted renally (70%) and via bile (20% fecal). Systemic absorption of triamcinolone acetonide after topical application is minimal (<1%).
