Antimalarial medicines constitute important tools to cure and prevent malaria infections, thereby averting death and disability; their role in reducing the transmission of malaria is becoming increasingly important. Effective medicines that are currently available include artemisinin‐based combination therapies (ACTs) for uncomplicated malaria, parenteral and rectal formulations of artemisinin derivatives and quinine injectables for severe malaria, and primaquine as an anti‐relapse agent. These medicines are not optimal, however, owing to safety considerations in specific risk groups, complex regimens, and less than optimal formulations. The efficacy of antimalarial medicines including currently used ACTs is threatened by parasite resistance. Resistance to artemisinins has recently been identified at the Cambodia–Thailand border. Intermittent preventive treatment is constrained by the lack of a replacement for sulfadoxine‐pyrimethamine. Despite increasing financial support to procure medicines, access to medicines by populations at risk of malaria, particularly in African countries, remains poor. This is largely due to weak health systems that are unable to deliver quality diagnostics and medicines through an efficient supply chain system, close at hand to the sick patient, especially in remote rural areas. Health systems are also challenged by incorrect prescribing practices in the informal and often unregulated private sector (an important provider of medicines for malaria) and the proliferation of counterfeit and substandard medicines. The provision of a more equitable access to life‐saving medicines requires no less than a steady drug development pipeline for new medicines tailored to meet the challenging conditions in endemic countries, ideally single dose, highly effective against both disease and relapse‐causing parasites and infective forms, extremely safe and with a long shelf life, and made available at affordable prices.
