Malaria during pregnancy is associated with low birth weight and increased perinatal mortality, especially among primigravidae. Despite increasing prevalence of malarial parasite resistance to sulfadoxine-pyrimethamine (SP), SP continues to be recommended for intermittent preventive treatment in pregnancy (IPTp). Women without

Sulfadoxine-pyrimethamine (SP) is used throughout Africa for intermittent preventive treatment (IPT) of malaria, but resistance threatens its efficacy. We found marked regional differences in the genotypes responsible for SP resistance when mapping recent surveys of dihydrofolate reductase (dhfr) and dihydropteroate

Pregnant women in malaria-endemic countries in sub-Saharan Africa are especially vulnerable to malaria. Recommended prevention strategies include intermittent preventive treatment with two doses of sulfadoxine-pyrimethamine and the use of insecticide-treated nets. However, progress with implementation has been slow and the

Annals of internal medicine, 106(5), 714-718 (1987-05-01)
The widespread emergence of chloroquine-resistant Plasmodium falciparum led to the formulation of an effective, fixed combination of two antimalarial agents, pyrimethamine and the long-acting sulfonamide sulfadoxine, for prophylaxis and treatment. These drugs act at sequential steps to inhibit the formation
