    -Suppressive therapy should continue for 8 weeks after leaving the endemic area. Approved indication: For the suppressive treatment of malaria due to Plasmodium vivax, P malariae, P ovale, and susceptible strains of P falciparum CDC Recommendations: 300 mg base (500 mg salt) orally once a week Comments: -For prophylaxis only in areas with chloroquine-sensitive malaria -Prophylaxis should start 1 to 2 weeks before travel to malarious areas; should continue weekly (same day each week) while in malarious areas and for 4 weeks after leaving such areas.

    Abstract The first proposed hypothesis about the mechanism of chloroquine CQ action on malaria parasites is DNA intercalation hypothesis which indicates that the site of CQ action is within the nucleus. Later on the interest of research was shifted from nucleus to lysosome due to the report of CQ accumulation within lysosome. Apr 02, 2019 Chloroquine is rapidly and almost completely absorbed from the gastrointestinal tract, and only a small proportion of the administered dose is found in the stools. Approximately 55% of the drug in the plasma is bound to nondiffusible plasma constituents. Excretion of chloroquine is quite slow, but is increased by acidification of the urine. To understand how chloroquine CQ enhances transgene expression in polycation-based, nonviral gene delivery systems, a number of CQ analogues with variations in the aliphatic amino side chain or in the aromatic ring are synthesized and investigated. Our studies indicate that the aliphatic amino moiety of CQ

    Approved indication: For acute attacks of malaria due to P vivax, P malariae, P ovale, and susceptible strains of P falciparum CDC Recommendations: Chloroquine-sensitive uncomplicated malaria (Plasmodium species or species not identified): 600 mg base (1 g salt) orally at once, followed by 300 mg base (500 mg salt) orally at 6, 24, and 48 hours Total dose: 1.5 g base (2.5 g salt) Comments: -For the treatment of uncomplicated malaria due to chloroquine-sensitive P vivax or P ovale, concomitant treatment with primaquine phosphate is recommended. 60 kg or more: 1 g chloroquine phosphate (600 mg base) orally as an initial dose, followed by 500 mg chloroquine phosphate (300 mg base) orally after 6 to 8 hours, then 500 mg chloroquine phosphate (300 mg base) orally once a day on the next 2 consecutive days Total dose: 2.5 g chloroquine phosphate (1.5 g base) in 3 days Less than 60 kg: First dose: 16.7 mg chloroquine phosphate/kg (10 mg base/kg) orally Second dose (6 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Third dose (24 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Fourth dose (36 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Total dose: 41.7 mg chloroquine phosphate/kg (25 mg base/kg) in 3 days Comments: -Concomitant therapy with an 8-aminoquinoline compound is necessary for radical cure of malaria due to P vivax and P malariae.

    Chloroquine as Intercalator a Hypothesis Revived S. R. Meshnick The mode of action of chloroquine is still controversial. Proposed mechanisms of action include I DNA intercalation, 2 lysosome accumulation and 3 binding to ferriprotoporphyrin IX. Recent data sug- gest that intercalation into parasite DNA A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen. 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.

They were randomized 12 to a calibration arm given radiotherapy RT alone 30Gy;5Gy/6fractions over 2 weeks, or an experimental arm given RT plus hydroxychloroquine HCQ, 200mg orally twice daily from 7 days prior to RT until progression/toxicity. The primary endpoint was one-year overall survival OS; target 34%.

    Chloroquine-Induced Neuronal Cell Death Is p53 and Bcl-2 Family. Chloroquine-Induced Neuronal Cell Death. The concentration- and time-dependent cytotoxic effects of CHQ were assessed by quantitating SYTOX Green nuclear labeling of nonviable cells and bisbenzimide labeling of all cell nuclei. Increasing CHQ concentrations 6.25–50 μM produced a proportional increase in cell death 48 h post-addition.
