CORTENEMA vs NYSTATIN-TRIAMCINOLONE ACETONIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
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.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.
Apply topically to affected area twice daily for 2-4 weeks.

1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
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 with renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
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%).
