SODIUM SULFACETAMIDE vs SULLA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfacetamide is a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, thereby blocking the synthesis of folic acid and ultimately nucleic acid synthesis, leading to bacteriostatic activity.
SULLA (sulfamethoxazole/trimethoprim) inhibits bacterial dihydropteroate synthase and dihydrofolate reductase, sequentially blocking folate synthesis and thereby nucleic acid production.
