Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
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.
0.5 mg orally once daily, with gradual taper to lowest effective dose
Apply thin layer to affected area twice daily for 2-4 weeks. Topical only.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
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: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
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%).
