Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfamethoxazole is a sulfonamide that inhibits bacterial dihydropteroate synthase, preventing folate synthesis. Trimethoprim inhibits bacterial dihydrofolate reductase, blocking tetrahydrofolate production. The combination produces sequential blockade of folate metabolism, leading to bactericidal activity.
Sulfisoxazole diolamine is a sulfonamide antibiotic that competitively inhibits dihydropteroate synthase, blocking the conversion of p-aminobenzoic acid (PABA) to dihydropteroic acid, thereby inhibiting bacterial folate synthesis and nucleic acid production.
800 mg orally every 12 hours for 5-7 days.
2-4 g orally initially, followed by 4-8 g/day in 4-6 divided doses for urinary tract infections; 6-8 g/day in 4-6 divided doses for nocardiosis.
