    Chloroquine resistant and sensitive areas

    Previously referred to as “Resochin”, Chloroquine was first discovered in 1924 at Bayer laboratories. Its first use was initially ignored as it was found to be toxic to people.

    The location of study sites with documented chloroquine resistance and chloroquine sensitive P. vivax is shown in Figure 2a and for chloroquine sensitive sites in Figure 2b below. Estimates for chloroquine sensitivity derived from 112 sites. In 50.9% of the sites estimates P. vivax were categorized as resistant. Chloroquine is used for the prophylaxis of malaria in areas of the world where the risk of chloroquine-resistant falciparum malaria is still low. It is also used with proguanil when chloroquine-resistant falciparum malaria is present. However, this combination may not be ideal. Treatment of uncomplicated falciparum malaria, only in areas where P. falciparum is still sensitive to chloroquine Central America, Haiti and Dominican Republic – Prophylaxis of falciparum malaria for non-immune individuals, only in areas where resistance to chloroquine is moderate and always in combination with proguanil. Forms and.

    These trials showed that chloroquine eliminated malaria and was appropriate to be used as an antimalarial drug. Thus, it was not until World War II that the government of the United States sponsored the clinical trials of chloroquine as an antimalarial drug.

    Both species are regarded as very sensitive to chloroquine, although there is a single recent report of chloroquine resistance in P. malariae. P. vivax is still generally very sensitive to chloroquine, although resistance is prevalent and increasing in some areas, notably Oceania, Indonesia and Peru. This chloroquine efflux occurs at a rate 40 to 50 fold faster among resistant parasites than that in sensitive ones.  Mutations in pfmdr­1 & 2 and pfcrt gene have also been associated with chloroquine resistance. Therefore, using culture-adapted isolates in in vitro assays, although occasionally misleading in some cases, may be an effective way of monitoring CQ susceptibility, especially in areas with low prevalence of CQ resistance. Chloroquine susceptibility of the 32 isolates assayed could be categorized into three levels, including S 17 isolates, MR 6 and HR 9, but could also be separated into sensitive and resistant categories with the cut-off value being an IC 50 of 100 nM.
