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. Drug interactions plaquenil Hydroxychloroquine lupus Rash from taking plaquenil Tinnitus chloroquine Researchers also hope that this model will allow drug designers to make structural adjustments to old, less effective malarial drugs and perhaps restore them to their former potency. Perhaps this could even be done by modifying chloroquine, introduced in the 1940s as the first effective antimalarial. As the threat of antimalarial drug resistance grows, there is increasing pressure to sustain the efficacy of existing treatments, develop alternative treatments, as well putting in place preventative measures such as bednets. Key drivers of antimalarial drug resistance It is unknown if P. malariae or P. ovale has developed resistance to any antimalarial drugs. P. knowlesi, a zoonotic monkey malaria that infects humans in forest fringe areas of Southeast Asia, is fully susceptible to chloroquine and other currently used drugs. Drug-resistant P. falciparum 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).
