TERFONYL vs TRYSUL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
TERFONYL is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, thereby blocking folate synthesis and bacterial DNA replication.
Trypanocidal agent; forms a complex with DNA and inhibits nucleic acid synthesis.
2 g intravenously every 12 hours over 24 hours for susceptible infections.
2 tablets (each containing sulfamethoxazole 400 mg and trimethoprim 80 mg) orally every 12 hours for 10-14 days.

Terminal elimination half-life is 2.5-4 hours in adults with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl < 30 mL/min).
Terminal elimination half-life: 8-10 hours in adults with normal renal function; prolonged to 20-30 hours in severe renal impairment (CrCl <30 mL/min).
Renal excretion accounts for 70-90% of elimination as unchanged drug via glomerular filtration and tubular secretion; biliary/fecal excretion constitutes 10-30%.
Renal: approximately 70-80% as unchanged drug via glomerular filtration and tubular secretion; biliary/fecal: 15-20% as metabolites; small amount in feces.
