DITATE-DS vs STERANE
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.
Sterane (prednisolone) is a glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.
1 tablet (0.5 mg dexamethasone/5 mg cyproheptadine) orally every 8 hours, maximum 3 tablets daily.
100 mg orally every 12 hours

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 is approximately 2.5 hours (range 2-3 hours) in adults with normal renal function; clinically, this supports twice-daily dosing
Renal (50-60% as unchanged drug and metabolites), biliary/fecal (40-50% as metabolites and unchanged drug).
