Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it. Cipro plaquenil Why malaria becomes resistant to chloroquine Hydroxychloroquine contraindications Methylene blue has intrinsic antimalarial activity and it can act as a chloroquine sensitizer. In addition, methylene blue must be considered for preventing methemoglobinemia, a serious complication of malarial anemia. As an antiparasitic agent, methylene blue is pleiotropic it Chloroquine-resistant cells efflux chloroquine at 40 times the rate of chloroquine-sensitive cells; the related mutations trace back to transmembrane proteins of the digestive vacuole, including sets of critical mutations in the P. falciparum chloroquine resistance transporter PfCRT gene. Proveblue, a methylene blue preparation, was found to exhibit antimalarial activity against Plasmodium falciparum strains in vitro. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

However recent studies has shown the efficacy of Methylene Blue as an effective and cheap antimalarial agent especially in countries with increasing resistance of P. falciparum to existing 1st line. Proveblue international patent PCT/FR/2007/001193, which is a methylene blue preparation that complies with the European Pharmacopoeia and contains limited organic impurities and heavy metals of recognized toxicity, has previously been demonstrated to possess in vitro antimalarial activity at a geometric mean 50% inhibitory concentration IC 50 of 3.62 nM against 23 Plasmodium falciparum strains that are resistant to various other antimalarials.
