Antimalarial medications, also known as antimalarials, are designed to prevent or cure malaria. Antimalarial drugs may be used for the treatment of malaria in individuals with suspected or confirmed infection, for the prevention of infection in individuals visiting a malaria-endemic region who have no immunity (Malaria prophylaxis) and for the Routine intermittent treatment of certain groups in endemic regions (Intermittent preventive therapy). Some antimalarial agents, particularly chloroquine and hydroxychloroquine, are also used in the treatment of rheumatoid arthritis and lupus-associated arthritis.

In the present book, twelve typical literatures about antimalarial drugs published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on medical science, virology, epidemiology, ect. We hope this book can demonstrate advances in antimalarial drugs as well as give references to the researchers, students and other related people.
