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.

A patient who survives the acute phase and is asymptomatic should be closely observed until all clinical features of toxicity resolve. Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion. 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.

SAR Of Artemisinin • Studies of artemisinin analogues such as deoxyartemisinin which do not contain the endoperoxide bridge, showed vastly reduced biological activity. • Moreover, derivatisation at the carbonyl lactone demonstrated that it is a possible region of modification that can be manipulated in order to improve pharmacokinetic properties.
