Artemisinin Combination Therapies, or ACTs, are currently the frontline treatments against malaria. Although these treatments are working well in many parts of the world, there is serious concern that malaria parasites are once again developing widespread resistance to this vital treatment.

Chloroquine-Sensitive Zones. Chloroquine is the drug of choice for travel to areas where chloroquine resistance has not been described. Chloroquine is active against the erythrocytic forms Fig. 6.3 of sensitive strains of all species of malaria, and it is also gametocidal against P. vivax, P. malariae, and P. ovale. Development of Chloroquine Resistance in Plasmodium falciparum. Drug resistance is the ability of a parasite to survive despite the presence of a drug that is meant to kill it in toxic levels. Resistance developed by most parasites that were initially sensitive to drugs mostly result from mutations in the genes responsive to the drug. Quinine comes from the bark of a tree native to South America. 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.

Chloroquine Aralen - Side Effects, Dosage, Interactions.. Chloroquine Resistance in Plasmodium falciparum - microbewiki. Chloroquine mechanism of drug action and resistance in.. Chloroquine resistance is widespread. Chloroquine should not be used for treatment of P. falciparum infections from areas of chloroquine resistance or malaria occurring in patients where chloroquine prophylaxis has failed. Patients infected with a resistant strains of plasmodia should be treated with another antimalarial drug. 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 digestive vacuole membrane. Rapid diagnostic assays for PfCRT mutations are already employed as surveillance tools for drug resistance. Although chloroquine is an antimalarial, it is often not sufficient for prophylaxis. Chloroquine used to be the antimalarial of choice and it was widely used for from 1947 onwards. As a result, the malaria parasites endemic to certain regions developed a resistance to chloroquine. Resistance to chloroquine was observed as early as the 1950s.
