NYSTATIN-TRIAMCINOLONE ACETONIDE vs ORTIKOS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
ORTIKOS (acalabrutinib) is a selective, irreversible inhibitor of Bruton tyrosine kinase (BTK). It forms a covalent bond with the active site cysteine residue (Cys481) in BTK, blocking downstream B-cell receptor signaling and inhibiting malignant B-cell proliferation and survival.
Apply topically to affected area twice daily for 2-4 weeks.
2 mg orally three times daily (total daily dose 6 mg).

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.
Terminal half-life of 8 hours (range 6-10) in healthy adults; prolonged to 24 hours in severe renal impairment (CrCl <30 mL/min).
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%).
Renal (70% unchanged), biliary/fecal (30% as metabolites)
