PENECORT vs TRIACIN-C
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
TRIACIN-C is a combination of triamcinolone (a corticosteroid) and nystatin (an antifungal). Triamcinolone suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis. Nystatin binds to ergosterol in fungal cell membranes, causing pore formation and cell death.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.
5 mg orally twice daily, taken with meals to enhance absorption.

Terminal elimination half-life: 3-4 hours in adults; prolonged in hepatic impairment (up to 8 hours).
Terminal elimination half-life: 7–9 hours. In patients with severe hepatic impairment (Child-Pugh C), half-life may extend to 15 hours; dosing adjustment recommended.
Renal: 60-70% as metabolites, 5-10% unchanged; Biliary/fecal: 20-30% as metabolites.
Renal: ~60% as unchanged drug; hepatic metabolism accounts for ~25% (primarily via CYP3A4), with biliary excretion of metabolites (~15%); fecal elimination <5%.
