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. Natural alternatives plaquenil Hydroxychloroquine drug guide Chloroquine resistance 12. The development and spread of drug-resistant strains of malaria parasites has been identified as a key factor in this resur- However, the efficiency of chloroquine has been severely impacted by the recent development of chloroquine resistant plasmodium falciparum parasites. The development of chloroquine resistance by malaria parasites is increasing at an alarming rate especially in the tropical countries where it is used extensively as an antimalarial drug 2. Factors that promote the development of drug resistance are more intense with P. falciparum compared to P. vivax and this explains the higher incidence of resistance in P. falciparum. Mechanisms of resistance. The biochemical mechanism of resistance has been well understood in cases of chloroquine, the antifolates, and atovaquone. 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).

Among 49 patients with falciparum malaria, we found neither parasites carrying haplotypes associated with chloroquine resistance nor instances of chloroquine treatment failure.
