It is bioactivated hepatically to its primary metabolite, N-desethylamodiaquine, by the cytochrome p450 enzyme CYP2C8. Among amodiaquine users, several rare but serious side effects have been reported and linked to variants in the CYP2C8 alleles.

Primaquine is a medication used to treat and prevent malaria and to treat Pneumocystis pneumonia. Specifically it is used for malaria due to Plasmodium vivax and Plasmodium ovale along with other medications and for prevention if other options cannot be used. Chloroquine is rapidly and almost completely absorbed from the gastrointestinal tract, and only a small proportion of the administered dose is found in the stools. Approximately 55% of the drug in the plasma is bound to nondiffusible plasma constituents. Excretion of chloroquine is quite slow, but is increased by acidification of the urine. People who are poor metabolizers of amodiaquine display lower treatment efficacy against malaria, as well as increased toxicity. CYP2C8*1 is characterized as the wild-type allele, which shows an acceptable safety profile, while CYP2C8*2, *3 and *4 all show a range of "poor metabolizer" phenotypes.

Chloroquine Phosphate is the phosphate salt of chloroquine, a quinoline compound with antimalarial and anti-inflammatory properties. Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Although the mechanism of action is not fully understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase.
