    Methylene blue falciparum chloroquine sensitize


    Methemoglobinemia may not resolve or may rebound after initial response to therapy with methylene blue in patients with methemoglobinemia associated with aryl amines (e.g., aniline) or sulfa drugs (e.g., dapsone). Has been used as a photosensitizer for photodynamic therapy† (PDT) for topical treatment of dermatologic or mucocutaneous infections (e.g., herpes labialis, eczema herpeticum, oral candidiasis, cutaneous leishmaniasis, chromoblastomycosis) When sodium nitrite is used for cyanide poisoning, do not use methylene blue in an attempt to treat excessive methemoglobinemia induced by the antidote because reduced cyanide binding and increased toxicity occurs.

    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. 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. Verapamil-Sensitive Transport of Quinacrine and Methylene Blue via the Plasmodium falciparum Chloroquine Resistance Transporter Reduces the Parasite's Susceptibility to these Tricyclic Drugs.

    Most cases of serotonin syndrome occurred when methylene blue was used as a diagnostic (visualizing) dye† (1–8 mg/kg IV) during parathyroid surgery in patients receiving a serotonergic drug; unclear whether there is a risk when methylene blue administered by other routes or in lower IV doses. (See Boxed Warning.) Manifestations of serotonin syndrome may include mental changes (e.g., confusion, hyperactivity, memory problems, agitation, hallucinations, delirium, coma), autonomic instability (e.g., tachycardia, labile BP, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or GI symptoms (e.g., nausea, vomiting, diarrhea).

  7. Methylene blue MB is the oldest synthetic antimalarial. It is not used anymore as antimalarial but should be reconsidered. For this purpose we have measured its impact on both chloroquine sensitive and resistant Plasmodium strains. We showed that around 5 nM of MB were able to inhibit 50 % of the parasite growth

    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. The combination of chloroquine and methylene blue is potentially effective for the treatment of chloroquine-resistant malaria caused by Plasmodium falciparum. The aim of this study was to investigate whether methylene blue influences the pharmacokinetics of chloroquine. In a randomized, placebo-controlled, parallel group design, a 3-day course of therapeutic oral doses of chloroquine total 2. Methylene blue has intrinsic antimalarial activity and it can act as a chloroquine. and it is a selective inhibitor of Plasmodium falciparum glutathione reductase. in glutathione depletion which sensitizes the parasite for chloroquine action.
