^NY (what is this?)  (verify)

Sulfadoxine (also spelled sulphadoxine) is an ultra-long-lasting sulfonamide used in combination with pyrimethamine to treat malaria.^[1]

It is also used to prevent malaria^[2] but due to high levels of sulphadoxine-pyrimethamine resistance, this use has become less common.^[3]

It is also used, usually in combination with other drugs, to treat or prevent various infections in livestock.^{[citation needed]}

Mechanism of action

Sulfadoxine competitively inhibits dihydropteroate synthase, interfering with folate synthesis.^{[citation needed]}
