Description
Mechanism of Action of Sulfadoxine and Pyrimethamine Combination
This combination of Sulfadoxine and Pyrimethamine works synergistically to treat malaria by targeting the folate synthesis pathway essential for the parasite’s survival.
- Sulfadoxine: As a long-lasting sulfonamide, sulfadoxine competitively inhibits dihydropteroate synthase, an enzyme critical for folate synthesis in the parasite. By hindering folate production, it prevents DNA and RNA synthesis, limiting parasite replication.
- Pyrimethamine: This antiparasitic agent inhibits the enzyme dihydrofolate reductase, preventing the regeneration of tetrahydrofolic acid from dihydrofolate. Tetrahydrofolic acid is necessary for DNA and RNA synthesis in many species, including the malaria-causing protozoa.
