DITATE-DS vs TRIACIN-C
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DITATE-DS is a combination of dexamethasone, a corticosteroid with anti-inflammatory and immunosuppressant properties, and trimethoprim, a folate antagonist. Dexamethasone acts by binding to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response. Trimethoprim inhibits dihydrofolate reductase, blocking bacterial folate synthesis and exerting antibacterial effects.
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.
1 tablet (0.5 mg dexamethasone/5 mg cyproheptadine) orally every 8 hours, maximum 3 tablets daily.
5 mg orally twice daily, taken with meals to enhance absorption.

Terminal elimination half-life is 4-6 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min), requiring dose adjustment.
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 (50-60% as unchanged drug and metabolites), biliary/fecal (40-50% as metabolites and unchanged drug).
Renal: ~60% as unchanged drug; hepatic metabolism accounts for ~25% (primarily via CYP3A4), with biliary excretion of metabolites (~15%); fecal elimination <5%.
