Malaria in pregnancy is potentially fatal to both the mother and the foetus particularly in the primigravidae. Implementation of appropriate control and preventive measures is challenged by the fact that malaria infection in pregnancy is often asymptomatic and parasitized red blood cells sequestrated in the placental microcirculation may not be detectable in the peripheral blood. In addition, the widespread prevalence of parasites resistant to chloroquine and sulphadoxine-pyrimethamine (SP) and, the safety concerns about newer antimalarials, poverty and inadequate supply have made antimalarial treatment options available to pregnant women very limited. These have necessitated an urgent search for alternative safe and efficacious treatment options for pregnant women. The objective of this study is to assess the efficacy, safety and tolerability of four antimalarial treatment options in rural Ghana within a programme setting.
