4 Drug and Medication Information
4.1 Drug Indication

Sulfadoxine is used in combination with pyrimethamine for the treatment or prevention of malaria. It can also be used to treat various infections in livestock as well. Sulfadoxine and pyrimethamine is indicated for the treatment of Plasmodium falciparum malaria in those patients in whom chloroquine resistance is suspected.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Sulfadoxine helps inhibit the enzyme dihydropteroate synthetase which is an enzyme necessary in the conversion of PABA to folic acid. As folic acid is vital to the synthesis, repair, and methylation of DNA which is vital to cell growth in Plasmodium falciparum. With this vital nutrient lacking, the parasite has difficulty in reproducing.


5.2 MeSH Pharmacological Classification

Anti-Infective Agents, Urinary

Substances capable of killing agents causing urinary tract infections or of preventing them from spreading. (See all compounds classified as Anti-Infective Agents, Urinary.)


Anti-Infective Agents

Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection. (See all compounds classified as Anti-Infective Agents.)


Antimalarials

Agents used in the treatment of malaria. They are usually classified on the basis of their action against plasmodia at different stages in their life cycle in the human. (From AMA, Drug Evaluations Annual, 1992, p1585) (See all compounds classified as Antimalarials.)

5.4 Mechanism of Action

Sulfadoxine is a sulfa drug, often used in combination with pyrimethamine to treat malaria. This medicine may also be used to prevent malaria in people who are living in, or will be traveling to, an area where there is a chance of getting malaria. Sulfadoxine targets Plasmodium dihydropteroate synthase and dihydrofolate reductase. Sulfa drugs or Sulfonamides are antimetabolites. They compete with para-aminobenzoic acid (PABA) for incorporation into folic acid. The action of sulfonamides exploits the difference between mammal cells and other kinds of cells in their folic acid metabolism. All cells require folic acid for growth. Folic acid (as a vitamin) diffuses or is transported into human cells. However, folic acid cannot cross bacterial (and certain protozoan) cell walls by diffusion or active transport. For this reason bacteria must synthesize folic acid from p-aminobenzoic acid.
