DEXAIR vs NYSTATIN AND TRIAMCINOLONE ACETONIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DEXAIR (dexamethasone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (e.g., cytokines, prostaglandins). It also inhibits leukocyte infiltration and reduces capillary permeability.
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: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.
Apply thin layer to affected area twice daily for 2-4 weeks. Topical only.

Terminal elimination half-life: 3.0-4.5 hours in adults with normal renal function; prolonged to 8-12 hours in severe renal impairment (CrCl <30 mL/min).
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.
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
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%).
