Detailed Description:
Plasmodium falciparum malaria kills over one million people and results in up to 500 million cases annually, affecting mainly young children and pregnant women. Artemisinin-based combination therapies (ACT) are considered today by WHO to be the best anti-malarials in terms of efficacy and lower propensity to resistance. Pyronaridine artesunate is a new ACT, in development to treat acute uncomplicated malaria. Pyronaridine and artesunate are antimalarial agents with a history of clinical use both separately and in combination with other drugs.Each drug has powerful antischizonticidal actions. The aim of a fixed dose combination of pyronaridine and artesunate in the treatment of uncomplicated acute malaria is to provide rapid reduction in parasitaemia with a three-day regimen, thereby improving compliance and reducing the risk of recrudescence through the slower elimination of pyronaridine.
