THIOSULFIL vs TRIPLE SULFOID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiosulfil (sulfamethizole) is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, blocking folic acid synthesis and thereby nucleic acid production.
Triple sulfoid (sulfadiazine, sulfamethazine, sulfamerazine) competes with para-aminobenzoic acid (PABA) to inhibit dihydropteroate synthase, blocking bacterial folate synthesis.
500 mg orally twice daily for 10-14 days.
2 tablets orally every 6 hours for 10-14 days; each tablet contains sulfadiazine 270 mg, sulfamerazine 270 mg, and sulfamethazine 270 mg.

Terminal elimination half-life is 2-4 hours in patients with normal renal function (creatinine clearance >80 mL/min); prolonged to 20-50 hours in severe renal impairment (CrCl <30 mL/min).
10-12 hours in normal renal function; prolonged to 24-48 hours in severe renal impairment (CrCl <30 mL/min)
Renal: 70-90% as unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal: <5%.
Renal: ~70% as unchanged drug; hepatic metabolism: ~20%; fecal: ~10%
