GANTRISIN vs TRIPLE SULFOID
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.
Triple sulfoid (sulfadiazine, sulfamethazine, sulfamerazine) competes with para-aminobenzoic acid (PABA) to inhibit dihydropteroate synthase, blocking bacterial folate synthesis.
2-4 g orally initially, then 4-8 g daily in 3-6 divided doses
2 tablets orally every 6 hours for 10-14 days; each tablet contains sulfadiazine 270 mg, sulfamerazine 270 mg, and sulfamethazine 270 mg.
