Sulfadoxine

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Sulfadoxine (also spelled sulphadoxine) is an ultra-long-lasting sulfonamide previously used in combination with pyrimethamine to treat or prevent malaria.[1] Due to high levels of resistance, its use is no longer recommended routinely.[2] It is also used, usually in combination with other drugs, to treat or prevent various infections in livestock.[3]

It is on the World Health Organization’s List of Essential Medicines, a list of the most important medication needed in a basic health system.[4]

Mechanism of action

Sulfadoxine competitively inhibits dihydropteroate synthase, interfering with folate synthesis.
