Dark-skinned persons may experience generalized pruritus that is not indicative of drug allergy. Retinal toxicity that may occur with long-term high doses of chloroquine used in the treatment of other diseases is extremely unlikely with chloroquine given as a weekly malaria chemosuppressive agent. Chloroquine hemolytic transfusion Hydroxychloroquine and citrus Chloroquine binds to heme or FP to form the FP-chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function. Action of the toxic FP-chloroquine and FP results in cell lysis and ultimately parasite cell autodigestion. Chloroquine is a 9-aminoquinoline that has been known since 1934. Specifically synthesised to be used as an antimalarial agent, chloroquine was subsequently shown to have immunomodulatory properties that have encouraged its application in the treatment of autoimmune diseases such as rheumatoid arthritis. 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. Because insufficient drug is excreted in breast milk to protect the infant, nursing infants should be given chloroquine. Chloroquine use is suitable for people of all ages and for pregnant women.

Remdesivir and chloroquine effectively inhibit the recently emerged novel coronavirus 2019-nCoV in vitro. which is in agreement with its putative anti-viral mechanism as a nucleotide analogue. Nov 15, 2015 However, note that Chloroquine has other properties as well that may be very well related to anti cancer mechanism, such as zinc ionophore, and others see below the section on mechanisms. In cancer, authophagy is the process used by cancer cells to “self-eat” in order to survive. Mechanism of Action Chloroquine, a 4-aminoquinoline, is an anti-protozoal agent. The precise mechanism by which chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme.
