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.
Triple sulfoid (sulfadiazine, sulfamethazine, sulfamerazine) competes with para-aminobenzoic acid (PABA) to inhibit dihydropteroate synthase, blocking bacterial folate synthesis.
800 mg orally every 12 hours for 5-7 days.
2 tablets orally every 6 hours for 10-14 days; each tablet contains sulfadiazine 270 mg, sulfamerazine 270 mg, and sulfamethazine 270 mg.
