This is the main mechanism of heme detoxification in Plasmodium parasites, occurring within the food vacuole, in which the acidic environment aids the chloroquine accumulation, due to its weak alkaline nature. Its use declined in the 1980's as piperaquine resistant strains of Plasmodium falciparum appeared and artemisinin derivatives became available. The drug chloroquine is bactericidal for Bacillus megaterium; it inhibits DNA and RNA biosynthesis and produces rapid degradation of ribosomes and dissimilation of ribosomal RNA. These effects were seen at exposure levels similar to clinical dosing in humans. [15], Overdosing can reduce the number of function of various kinds of blood cells, including loss of red blood cells, methemoglobinemia, and loss of white blood cells. Use in Malaria: Primaquine has been the only 8-amino quinoline drug available since 1952 for the radical cure of P. vivax (and P. ovale) malaria by its action on the dormant hypnozoites. Primaquine.

OH-PQm exert modest antimalarial efficacy against parasite gametocytes; however, potency is enhanced ca.1000 fold in the presence of cytochrome P450 NADPH:oxidoreductase (CPR) from the liver and bone marrow. Primaquine is an 8-aminoquinolone drug commonly used for the chemoprophylaxis and treatment of avian malarial infections in managed penguin populations worldwide. Our findings provide new insight into molecular mechanism(s) underlying the presynaptic action of nitric oxide on inhibitory neurotransmission. 0.5 mg/kg daily in NoN G6PD deficient, Fast acting drugs can be used singly to treat attacks of malarial fever: faster acting drugs are preferred in falciparum malaria where delay in treatment may result in death even if the parasites are cleared from blood. The metabolism of Acalabrutinib can be decreased when combined with Piperaquine. One small clinical trial of pamaquine as a causal prophylactic was disappointing[3] (whereas primaquine is an extremely effective causal prophylactic). In 1926, Roehl demonstrated that pamaquine was effective in treating malaria in birds, and introduced it into use in humans. Primaquine, an 8-aminoquinoline, is the only medication approved by the World Health Organization to treat the hypnozoite stage of Plasmodium vivax and P. ovale malaria.
