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. Diseases treated with plaquenil Can long-term use of plaquenil causing low-blood sugar Plaquenil black box warning Methylene blue MB combined with chloroquine CQ has been considered as one promising new regimen. The primary objective of this study was to evaluate the safety of CQ-MB in African children with uncomplicated falciparum malaria. Secondary objectives were to assess the efficacy and the acceptance of CQ-MB in a rural population of West Africa. Dr. Eric Baret is a Pediatrician in Carrollton, GA.

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.

Another advantage of using methylene blue in combination with antimalarial drugs is its activity against the gametocyte stages, which can reduce the transmission of P. falciparum. Ex vivo activity of Proveblue, a methylene blue, against.. A Partial Convergence in Action of Methylene Blue and.. In Vitro Activity of Proveblue Methylene Blue on Plasmodium.. 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. 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 The development of safe, effective and affordable drug combinations against malaria in Africa is a public health priority. Methylene blue MB has a similar mode of action as chloroquine CQ and has moreover been shown to selectively inhibit the Plasmodium falciparum glutathione reductase. In 2004, an uncontrolled dose-finding study on the combination MB-CQ was performed in 435 young children.
