    Mode of action of chloroquine


    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.

    What family of drugs does chloroquine belong to Chloroquine class of drug

    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. Chloroquine Mode of Action Science The drug chloroquine is bactericidal for Bacillus megaterium ; it inhibits DNA and RNA biosynthesis and produces rapid degradation of ribosomes and. Mechanism of action Chloroquine basic concentrates in parasite food vacuole acidic. Prevent heme polymerization into hemozoin causing heme accumulation toxic to parasite. Drug complex with heme disrupt cell membrane function. Other mechanism include intercalating of parasite DNA, DNA synthesis inhibition. 7.

    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.

    The lysosomal inhibitor, chloroquine, increases cell surface. Sep 15, 2013 Under these conditions, very little receptor was observed at the cell surface suggesting rapid turnover of the receptor and accumulation in the lysosome. Treatment with chloroquine also resulted in lysosomal accumulation, but also appeared to increase GFP-tagged BMPR-II at the cell surface Fig. 2 K–N; arrowheads.
