white, odorless, bitter tasting, crystalline substance, freely soluble in water. Resistance developed by most parasites that were initially sensitive to drugs mostly result from mutations in the genes responsive to the drug Jul 23, 2018 · Resistance to currently available antimalarial drugs has been confirmed in only two of the four p falciparum resistance to chloroquine human malaria parasite species, Plasmodium falciparum and P. They then spread through South and Southeast Asia and by …. Most likely, CQR has spread from Southeast Asia (SEA) to the Indian mainland through NE India Efﬁcacy of Chloroquine for Treatment of P. Since verapamil is known to reverse the P-glycoprotein-mediated efflux of drugs in multidrug-resistant tumor cells (Martin et al., 1987), this led to the proposal that efflux of chloroquine by a plasmodial P-glycoprotein is responsible for chloroquine resistance Some strains of P. The reversal of chloroquine resistance by verapamil suggested a similar mammalian tumor cells multidrug-resistant phenotype in malaria Injection 50 mg, 100 mg base (as phosphate or sulfate) per ml in 2-ml ampoule [chloroquine base 150 mg is equivalent to chloroquine sulfate 200 mg or Chloroquine phosphate 250 mg] General information Policy regarding the use of this drug as an antimalarial must be determined nationally since in many areas P.
