With concentrated malaria eradication efforts currently underway, monitoring drug resistance in clinical settings complemented by in vitro drug susceptibility assays and analysis of resistance markers, becomes critical to the implementation of an effective antimalarial drug policy. Understanding of the factors, which lead to the development and spread of drug resistance, is necessary to design optimal prevention and treatment strategies. Plaquenil reduction Plaquenil dx code Nov 19, 2010 Resistance to chloroquine of malaria strains is known to be associated with a parasite protein named PfCRT, the mutated form of which is able to reduce chloroquine accumulation in the digestive vacuole of the pathogen. Chloroquine, or hydroxychloroquine, has been used to treat malaria since 1944. It can be given before exposure to malaria to prevent infection, and it can also be given as treatment afterward. Malaria is a disease that is caused by a parasite, unlike COVID-19. The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. The development of resistance to drugs poses one of the greatest threats to malaria control and results in increased malaria morbidity and mortality. This review attempts to summarize the unique factors presented by malarial parasites that lead to the emergence and spread of drug resistance, and gives an overview of known resistance mechanisms to currently used antimalarial drugs.

Haemoglobin is transported to an organelle called the digestive vacuole where it is degraded, releasing amino acids and the toxic molecule, haem. Malaria understanding drug resistance - BugBitten. Chloroquine mechanism of drug action and resistance in.. Drug resistance in malaria - World Health Organization. The mechanisms of chloroquine accumulation in the food vacuole have been proposed to be accumulation of chloroquine in the food vacuole as a result of increased acidity, presence of a carrier in the parasite and the presence of a receptor in the vacuole that chloroquine can bind to 10. Oct 01, 2018 Prophylaxis of malaria in geographic areas where resistance to Chloroquine is not present. Treatment of extraintestinal amebiasis. Chloroquine phosphate tablets do not prevent relapses in patients with vivax or ovale malaria because it is not effective against exoerythrocytic forms of the parasites. Chloroquine has been the standard of care for P. falciparum malaria for more than 40 years but the spread of resistant parasites in all malaria endemic regions has led to abandonment of the drug.
