HYDELTRA-TBA vs NYSTATIN-TRIAMCINOLONE ACETONIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene transcription to suppress inflammation, immune response, and adrenal function.
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.
20-40 mg intramuscularly every 3 weeks; for intra-articular use: 20-40 mg per large joint, 10-20 mg per medium joint, 4-10 mg per small joint.
Apply topically to affected area twice daily for 2-4 weeks.

Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
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 renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <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%).
