    It is a rapidly acting drug, targeting the asexual stage. The mortality rate has increased along with the spread of malaria. p H of food vacuole of plasmodium specie is acidic while chloroquine is a weak base, leading to change in p H of food vacuole. More effective for long term treatment of rheumatoid arthritis as devoid of long term adverse drug reactions, especially eye changes. Use of chloroquine is declining recently due to the fact that most strains have become resistant. It rapidly enters and gets concentrated in food vacuole, present within erythrocytes. If we want to avoid relapse, Primaquine is used to eradicate tissue schizontal activity. Previously used for chemoprophylaxis, now due to development of resistance, chloroquine is not used. Anti-amoebic effect –infection caused by Entamoeba histolytica) Amebic liver abscess (as chloroquine is concentrated in the liver) because: Used for long time for rheumatoid arthritis, but because of associated ocular adverse effects, precaution is taken to have eye examination every 4 to 6 month to check retinal changes.

    Oct 01, 2018 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. It can also inhibit certain enzymes by its interaction with DNA. Onset of Action for Chloroquine 2 - 3 days Duration of Action for Chloroquine 7 days Half Life of Chloroquine 3 - 10 days Side Effects of Chloroquine 1. Nausea 2. Vomiting 3. Diarrhoea 4. Abdominal cramps 5. Pruritis 6. Headache 7. Dizziness 8. Hypotension 9. Visual disturbances Contra-indications of Chloroquine 1. Hypersensitivity to Chloroquine and other 4 Amino quinolines 2. Porphyria 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. Many theories have been developed to elucidate the chloroquine mechanism of action, including DNA binding and inhibition of various enzymes and/or transporters.

    Plasmodium develops, multiplies and transforms by utilizing hemoglobin of human erythrocytes. Inhibits phospholipase A2 (used rheumatoid arthritis), chemotaxis is decreased, resulting in decreased proliferation of antigen. Primarily highly effective against febrile illness, relief is quickly achieved within 24 hours. CRTF Another gene involved is chloroquine resistance transporter factor (CRTF) 4. When administered, patient becomes afebrile within 24-48 hours. Resistance has developed in Afghanistan and Khyber Pathtunkhua.

    General antimicrobial mechanism of action of chloroquine. Chloroquine accumulates in very high concentrations in the parasite food vacuole Geary et al. 1986. Once in the food vacuole, chloroquine is thought to inhibit the detoxification of heme. Chloroquine becomes protonated to CQ 2+ because the digestive vacuole is acidic pH 4.7 Mechanism of action of chloroquine. Entry into the parasitized RBCs; 1. Accumulation in food vacuole of the parasite- role of pH gradient chloroquine trapping Affects asexual cycle of plasmodium specie. Once administered, it has to enter site of action.

    Genetic architecture of artemisinin-resistant Plasmodium falciparum. Analysis of the fine structure of the parasite population showed that the fd, arps10, mdr2 and crt polymorphisms are markers of a genetic background on which kelch13 mutations are particularly likely to arise and that they correlate with the contemporary geographical boundaries and population frequencies of artemisinin resistance.

    Does anyone take methotrexate and hydroxychloroquine. - NRAS I was diagnosed with RA in march and have been on increasing dose of methotrexate. Yesterday my rheumatologist started me on hydroxychloroquine as well. Is anyone else on this combination and have you had any problems with it as I know hydroxychloroquine can cause eye sight problems. Thanks
