    Chloroquine resistant plasmodium falciparum treatment


    Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. However, resistance to the drug also rapidly emerged, with the first cases of not being cured by administration of chloroquine being reported in the 1950s.

    Chloroquine has long been used in the treatment or prevention of malaria from Plasmodium vivax, P. ovale, and P. malariae, excluding the malaria parasite Plasmodium falciparum, for it started to develop widespread resistance to it. Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence. Abstract. Background. Due to development of multidrug-resistant Plasmodium falciparum new antimalarial therapies are needed. In Guinea-Bissau, routinely used triple standard-dose chloroquine remained effective for decades despite the existence of “chloroquine-resistant” P. falciparum. Drug-resistant P. falciparum. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted.

    Nowadays, other drugs, and notably ones containing artemisinin-based compounds, are preferentially used to treat uncomplicated malaria and especially in areas where chloroquine resistance is known to occur. Since then, resistance has spread rapidly (since obviously it is beneficial to the parasite to be resistant, so various mutations conferring this protection have arisen multiple times in different areas in the world and also been passed on preferentially to new generations of malaria parasites), and now chloroquine resistant are found in multiple locations in south-east Asia, such as Myanmar and India, as well as from Guyana in South America.

    Abstract. The development of chloroquine as an antimalarial drug and the subsequent evolution of drug-resistant Plasmodium strains had major impacts on global public health in the 20th century. In P. falciparum the cause of the most lethal human malaria, chloroquine resistance is linked to multiple mutations in PfCRT, a protein that likely functions as a transporter in the parasite’s. We obtained 78 human blood samples from areas in Haiti with high transmission of malaria and found no drug resistance–associated mutations in Plasmodium falciparum chloroquine resistance transporter and Kelch 13 genes. We recommend maintaining chloroquine as the first-line drug for malaria in Haiti. Artemisinin-based therapy can be used as alternative therapy. Emerging resistance to chloroquine CQ by Plasmodium vivax threatens the health of the hundreds of millions of people routinely exposed to the risk of infection with this organism. CQ has been the first-line therapy for vivax malaria since 1946 32, 115.

    Chloroquine is the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat amebiasis, an infection of the intestines caused by a parasite.

    Generic Plaquenil - Antibiotics Home Page Several drug companies currently manufacture generic Plaquenil hydroxychloroquine, including Sandoz, Mylan Pharmaceuticals, and Watson Laboratories. The generic medication, which is sold by the name hydroxychloroquine, is only available in a 200 mg strength.
