    Pharmacokinetics of quinine chloroquine and amodiaquine

    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.

    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. 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. The quinoline antimalarials quinine, chloroquine, amodiaquine, primaquine and mefloquine comprise the majority of world antimalarial drug usage. These compounds have narrow therapeutic ratios. None of them is younger than twenty years old. The object of this article is to illustrate howthe treatmentofmalaria.

    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.

  6. It is the first-line treatment for P. falciparum complicated malaria and is a treatment option for P. falciparum uncomplicated malaria in chloroquine-resistant regions. 25–27 Quinine seems to act against Plasmodium spp. by inhibiting haem polymerase that leads to toxic haem levels. 27 Quinine metabolism is interesting because acute malaria influences absorption, the binding-protein fraction, CYP450 activity and excretion of quinine.

As quinine is a lipophilic drug and has low hepatic clearance with a narrow therapeutic index, significant alterations in the pharmacokinetics of quinine in obese individuals might have clinical implications with respect to dosage regimens in obese patients.

    Chloroquine C18H26ClN3 - PubChem Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite.
