Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

Several artemisinin derivatives have been developed for clinical use in prevention and treatment of malaria, some of which have been linked to rare instances of acute liver injury. Therefore, artemisinin-based combination therapy ACT is recommended for the treatment of P. falciparum malaria. Fast acting artemisinin-based compounds are combined with a drug from a different class. Compound formulations have been developed for artemether, artesunate and dihydroartemisinin, as described below. Artemisinin was first announced to the rest of the world in 1979. At first, biological chemists were puzzled by the apparent stability of the hitherto unknown 15-carbon sesquiterpene peroxide structure. A full chemical synthesis was reported 4 years later, although, as for quinine, this remains too expensive for commercialization. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

Qinghaosu Artemisinin The Price of Success Science. Genetic architecture of artemisinin-resistant Plasmodium.. Efforts are ongoing to make other antimalarial compounds based on the structure of artemisinin and its mechanism of action. It is known that artemisinin requires hemoglobin digestion and the release of iron containing heme, which induces oxidative stress Klonis et al. 2011. Chloroquine is an aminoquinoline that is quinoline which is substituted at position 4 by a 5-diethylaminopentan-2-ylamino group at at position 7 by chlorine. It is used for the treatment of malaria, hepatic amoebiasis, lupus erythematosus, light-sensitive skin eruptions, and rheumatoid arthritis. Artemisinin is effective against all the malaria-causing protozoal organisms in the genus Plasmodium. The drug is particularly useful in the treatment of infections involving chloroquine -resistant parasites and infections involving multidrug-resistant P. falciparum, which is the deadliest of the malaria protozoans.
