GANTRISIN vs SODIUM SULFACETAMIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive inhibitor of dihydropteroate synthase, blocking para-aminobenzoic acid (PABA) incorporation into dihydropteroic acid, thereby inhibiting bacterial folate synthesis and nucleic acid production.
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.
