SATRIC vs SEPTRA GRAPE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
SATRIC is a combination of sulfathiazole, sulfacetamide, and sulfabenzamide, which are sulfonamide antibiotics. They competitively inhibit dihydropteroate synthase, blocking folate synthesis in susceptible bacteria.
Septra Grape (trimethoprim/sulfamethoxazole) inhibits bacterial folic acid synthesis via sequential blockade: sulfamethoxazole inhibits dihydropteroate synthase, and trimethoprim inhibits dihydrofolate reductase, leading to bactericidal activity.
No standard dosing information available for SATRIC.
160 mg trimethoprim / 800 mg sulfamethoxazole (1 double-strength tablet) orally every 12 hours.

3-5 hours in healthy adults; prolonged to 6-8 hours in renal impairment (CrCl < 30 mL/min)
Trimethoprim: 8-10 hours (renal impairment >24h). Sulfamethoxazole: 10-13 hours (acetylation phenotype; prolonged in renal impairment). Clinical: Dosing interval generally 12h; adjust CrCl <30 mL/min.
Renal: 70% unchanged; fecal: 20%; biliary: 10%
Renal: 50-70% unchanged (trimethoprim), 30-50% as N-acetyl metabolite; sulfamethoxazole: 70-80% as metabolites, 20-30% unchanged; biliary excretion minimal (<5% total).
