According to legend it was first brought to Europe by a Countess who had been treated with it in Peru in the 1600s. In 1820, two French chemists isolated quinine from the cinchona bark and quinine became a treatment of reference for intermittent fever throughout the world. Quinine remains an important and effective treatment for malaria today, despite sporadic observations of quinine resistance. Hydroxychloroquine mechanism of action ra What else can i take if i cant take plaquenil Hydroxychloroquin cardiac protective During the past year, confirmed chloroquine-resistant infections have been described from specific areas in Zambia 3 and Sudan 4; previously, Kenya, Tanzania, Uganda, Madagascar, and the Comoros Islands were acknowledged to have transmission of chloroquine-resistant P. falciparum. Prevalence of mutations conferring resistance to sulfadoxine–pyrimethamine dhfr and dhps and chloroquine pfcrt in Plasmodium falciparum isolates from Karonga and Blantyre in Malawi, and in the Mbeya region in south‐west Tanzania Schönfeld et al. 2007 Chloroquine resistance was demonstrated for the ﬁ rst time in semi-immune Tanzanians in 1982. 11 The following year, a chloroquine resistance rate of 34% was reported among a Zanzibar school population. 12 Studies con- These compounds belonged to a new class of antimalarials, the four-amino quinolines. Research by German scientists to discover a substitute for quinine led to the synthesis in 1934 of Resochin (chloroquine) and Sontochin (3-methyl-chloroquine).

Chloroquine - Wikipedia. Chloroquine is still the drug of choice for the treatment of uncomplicated falciparum malaria in most of sub-Saharan Africa. But the increasing number of therapeutic failures with chloroquine has led to concern about whether this drug can remain effective for long in Africa. Before deciding to change the drug policy on the first-line antimalarial treatment, the extent of true drug resistance.

Plasmodium falciparum resistance to anti-malarial drugs remains a major obstacle to the control of malaria. In 2001 Tanzania replaced chloroquine CQ with sulphadoxine-pyrimethamine SP as first-line drug, which in turn was replaced by artemisinin combination therapy in 2006.
