    Drug of choice for chloroquine resistant malaria


    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.

    Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted. P. falciparum has also developed resistance to nearly all of the other currently available antimalarial drugs, such as sulfadoxine/pyrimethamine, mefloquine, halofantrine, and quinine. For destinations where any chloroquine-resistant malaria is present, in addition to mosquito avoidance measures, prophylaxis options are atovaquone-proguanil, doxycycline, mefloquine, and tafenoquine. ANSWER There are a number of medicines used to treat malaria. Traditionally, chloroquine has been the first line drug of choice for uncomplicated, non-resistant malaria. However, several types of malaria, and most notably Plasmodium falciparum, the most severe and deadly kind, has become resistant to chloroquine in many places.

    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).

    For P. falciparum infections acquired in areas without chloroquine-resistant strains, which include Central America west of the Panama Canal, Haiti, and the Dominican Republic, patients can be treated with oral chloroquine. A chloroquine dose of 600 mg base = 1,000 mg salt should be given initially, followed by 300 mg base = 500 mg salt at 6, 24, and 48 hours after the initial dose for a total chloroquine dose of 1,500 mg base =2,500 mg salt. Chloroquine is the drug of choice in the few malaria-endemic areas free of CRPf. Combining chloroquine and proguanil is an option for CRPf when other first-line antimalarials are contraindicated. Combining chloroquine and proguanil is an option for CRPf when other first-line antimalarials are contraindicated. Artemisinin has been a very potent and effective antimalarial drug, especially when used in combination with other malaria medicines. 3 Combining an artemisinin drug with a partner drug that has a longer half-life was found to improve the efficacy of the artemisinin.

    Chloroquine for research Cell-culture tested InvivoGen Chloroquine is a lysosomotropic agent that prevents endosomal acidification 1. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes.
