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. What is hydroxychloroquine made of Plaquenil tamoxifen toxic symptoms Quinine is active against the Plasmodium falciparum strain and may be used where other medicines – such as chloroquine or artesunate – are either ineffective or unavailable. Quinine is most effective at treating uncomplicated malaria. It becomes progressively less effective at treating more complicated, severe forms of malaria. The pharmacokinetics of artesunate and amodiaquine and their main active metabolites dihydroartemisinin and desethylamodiaquine were compared following monotherapy and combination therapy using analysis of variance. Chloroquine, noncurative, and amodiaquine, partially curative, have nearly the same initial dose-independent killing with a lag phase of minimal parasite reduction at all doses between 6 and 24. 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.
