Approximately 4 months after his arrival he begins to experience episodes of flu-like symptoms including fever, chills, fatigue and sweating. He goes to local free health clinic, where he is diagnosed with malaria, and given a prescription for chloroquine. Hydroxychloroquine sulfate for rheumatoid arthritis Plaquenil and pink eye Antimalarial mode of action and resistance. Chloroquine acts exclusively in the erythrocyte stage of malaria parasites. The antimalarial mechanism of action from chloroquine has not been fully elucidated. Doxycycline is a slow-acting blood schizontocidal agent that is highly effective at preventing malaria. In areas with chloroquine and multidrug-resistant P. falciparum parasites, doxycycline has already been successfully used in combination with quinine to treat malaria, and it has been proven to be effective and well-tolerated. Malaria Mode of action of chloroquine and mechanism of chloroquine resistance Article PDF Available in Journal de Pharmacie Clinique 323143-153 September 2013 with 415 Reads In 2012 the CDC estimated there were 627,000 estimated deaths due to malaria (CDC: Malaria, 2015). His symptoms disappear soon after beginning chloroquine therapy, but several months later his symptoms reappear., and one of the leading causes of death and disability (Figure 1).

As the mechanism of action appears to be distinct from the mechanism of resistance, this identifies a vulnerable target for the development of new. Chloroquine Mechanism of drug action and resistance in.. Malaria Mode of action of chloroquine and mechanism of.. How does methylene blue’s mode of action differ from chloroquine in.. Chloroquine. Chloroquine is the prototype anti malarial drug, most widely used to treat all types of malarial infections. It is also the cheapest, time tested and safe anti malarial agent. Mechanism of action The mechanism of action of chloroquine is unclear. Being alkaline, the drug reaches high concentration within the food vacuoles of the. The major action of chloroquine is to inhibit the formation of hemozoin Hz from the heme released by the digestion of hemoglobin Hb. The free heme then lyses membranes and leads to parasite death. Chloroquine resistance is due to a decreased accumulation of chloroquine in the food vacuole. The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial.
