Pyrimethamine + Sulfadoxine is an antimalarial combination.
Pyrimethamine works by inhibiting the enzyme dihydrofolate reductase (DHFR). This enzyme is responsible for converting one form of folate into another active form that the malaria parasite needs for DNA synthesis and cell growth.
Sulfadoxine inhibits the enzyme dihydropteroate synthase (DHPS), preventing the conversion of a specific compound into a precursor of folate. The malaria parasite requires this precursor to produce folate.
