Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone acetate is a synthetic glucocorticoid receptor agonist that modulates gene expression to suppress inflammation, immune responses, and adrenal function by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.
Nystatin is a polyene antifungal that binds to ergosterol in the fungal cell membrane, forming pores that cause leakage of intracellular contents and cell death. Triamcinolone acetonide is a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), thereby inhibiting the release of arachidonic acid and reducing prostaglandin and leukotriene synthesis, leading to anti-inflammatory, antipruritic, and vasoconstrictive effects.
IV: 10-40 mg every 1-2 weeks; IM: 40-120 mg every 1-4 weeks; Intra-articular/soft tissue: 4-80 mg per injection, repeat every 1-5 weeks as needed.
Apply topically to affected area twice daily for 2-4 weeks.

Plasma terminal elimination half-life: 2.5-4.0 hours (methylprednisolone acetate formulation). Duration of adrenal suppression correlates with tissue esterase hydrolysis and prolonged tissue retention.
Nystatin: negligible systemic half-life due to lack of absorption. Triamcinolone acetonide: terminal half-life ~2-5 hours (mean ~3.5 h) after intravascular administration; prolonged in hepatic impairment.
Primarily hepatic metabolism; renal excretion of metabolites (<10% unchanged). Fecal excretion is minor (<5%).
Nystatin: negligible systemic absorption; excreted unchanged in feces (~100%). Triamcinolone acetonide: metabolized hepatically; renal excretion of metabolites (~40%) and unchanged drug (<5%); fecal excretion (~60%).
