DailyMed - CHLOROQUINE PHOSPHATE tablet. A dual fluorescent Plasmodium cynomolgi reporter line reveals in vitro.. 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. Whether the protein mediates extrusion of the drug acting as a channel or as a carrier and which is the protonation state of its chloroquine substrate is the subject of a. Hydroxychloroquine can be detected in the cord blood at delivery in concentrations similar to those in the maternal serum Costedoat-Chalumeau 2002.
