Hydroxychloroquine for autoimmune diseases Hydroxychloroquine prononciation Lupus hydroxychloroquine sulfate Plasmodium falciparum chloroquine resistance is a major cause of worldwide increases in malaria mortality and morbidity. Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. 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. Plasmodium vivax resistance to chloroquine CQRPv is difficult to detect due to the low level of parasitaemia among parasite carriers and also to distinguish from relapses to reinfections. The first reports of CQRPv were from 1989 3, 4, 30 years after the resistance report for Plasmodium falciparum. One dose is taken beginning 2 weeks before traveling to an area where malaria is common, while you are in the area, and then for 8 weeks after you return from the area.

If weakness occurs, discontinue the drug. However, the rapid in vitro test may be considerably improved and may prove to be an accurate diagnostic tool for chloroquine resistance if the incubation period is extended to 12 to 24 h, or even to 42 h. Chloroquine is an anti-malaria medicine that works by interfering with the growth of parasites in the red blood cells of the human body. Parasites that cause malaria typically enter the body through the bite of a mosquito.
