SULF-10 vs SULFAIR-15
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfacetamide inhibits bacterial dihydropteroate synthase, blocking folate synthesis and thereby nucleic acid production.
Sulfadoxine is a long-acting sulfonamide that inhibits dihydropteroate synthase, blocking folate synthesis. Pyrimethamine inhibits dihydrofolate reductase, synergistically inhibiting nucleic acid synthesis in Plasmodium species.
One to two drops of SULF-10 ophthalmic solution (10% sulfacetamide sodium) instilled into the affected eye(s) every 2-3 hours initially, then decreasing frequency as infection resolves, up to 5-6 times daily.
15 mg orally every 6 hours, not to exceed 60 mg/day.

Terminal elimination half-life is 7-12 hours in adults with normal renal function; prolonged in renal impairment
12–15 hours in healthy adults; prolonged to 20–30 hours in moderate hepatic impairment.
Renal excretion of unchanged drug and acetylated metabolites: ~85-90%; biliary/fecal: ~10-15%
Renal excretion unchanged: 70%; hepatic metabolism to inactive metabolites: 20%; fecal excretion: 10%.
