GANTANOL vs SULLA
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.
SULLA (sulfamethoxazole/trimethoprim) inhibits bacterial dihydropteroate synthase and dihydrofolate reductase, sequentially blocking folate synthesis and thereby nucleic acid production.
