Abstract

African children under 5 years of age bear the main burden of global malaria mortality. Seasonal malaria chemoprevention (SMC) with sulfadoxine-pyrimethamine (SP) plus amodiaquine (AQ) given monthly during the rainy season is a highly effective malaria intervention for children aged between 3 months and 5 years living in the Sahel region, a region of intense but seasonal malaria transmission. This intervention is now being considered for other regions of Africa where malaria parasites are more drug resistant. Dihydroartemisinin-piperaquine (DP), an artemisinin-based combination therapy (ACT), has proved to be highly effective and well tolerated in intermittent preventive treatment in pregnant women and children. This combination may be a suitable alternative for SMC. Understanding the safety, pharmacokinetic and pharmacodynamic properties of antimalarial combination therapies is crucial in optimising dosing.
