DITATE-DS vs SERVISONE
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.
SERVISONE is a corticosteroid that exerts anti-inflammatory and immunosuppressive effects by binding to glucocorticoid receptors, modulating gene transcription, and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
1 tablet (0.5 mg dexamethasone/5 mg cyproheptadine) orally every 8 hours, maximum 3 tablets daily.
10-20 mg orally once daily in the morning; higher doses up to 40 mg daily for severe cases.

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 3-4 hours. Clinically, this supports twice-daily dosing for sustained effect.
Renal (50-60% as unchanged drug and metabolites), biliary/fecal (40-50% as metabolites and unchanged drug).
Renal (70-80% as metabolites, 5-10% unchanged); fecal/biliary (15-20%)
