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. Cbd and hydroxychloroquine Chloroquine blood to plasma ratio Skin changes with plaquenil Calcium loss hydroxychloroquin therapy Aminoquinoline, excellent schizonticide, Antimalarial, amebicide, anti inflammatory and local irritant. Mechanism of Action of Chloroquine Malarial parasites digest their own haemoglobin and release highly toxic heme. This heme is used up by parasitic polymerase enzyme and converted to non toxic haemozoin. Since Chloroquine is. MECHANISM OF ACTION Acts on trophozoites. Has no effect on cysts. Nitro group of metronidazole is reduced by protozoan leading to cytotoxic reduced product that binds to DNA and proteins resulting into parasite death. is active against the invasive form in gut and liver. The metronidazole metabolites are taken up into bacterial DNA, and form unstable molecules. Chloroquine mechanism of drug action and resistance in Plasmodium falciparum. Slater AF1. Author information 1Picower Institute for Medical Research, Manhasset, NY 11030. Quinoline-containing drugs such as chloroquine and quinine have had a long and successful history in antimalarial chemotherapy. 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.

The parasite digests the host cell’s hemoglobin to obtain essential amino acids ii. The process releases large amounts of heme, which is toxic to the parasite iii. To protect itself the parasite ordinarily polymerizes the heme to nontoxic hemozoin, which is sequestered in. Stereoselectivity in chloroquine body disposition could be responsible for this discrepancy. Chloroquine binding to plasma proteins is stereoselective, favouring S+-chloroquine 67% vs 35% for the R-enantiomer. Hence, unbound plasma concentrations are higher for R−-chloroquine. Inhibition of DNA replication is proposed as a general mechanism of the antimicrobial action of chloroquine. The drug chloroquine is bactericidal for Bacillus megaterium ; it inhibits DNA and RNA.
