Sulfadoxine
Introduction
Overview
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
Mechanism of action
Sulfadoxine competitively inhibits dihydropteroate synthase, interfering with folate synthesis.
