    Chloroquine mode of action


    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.

    An important mode of action of chloroquine and hydroxychloroquine is the interference of lysosomal activity and autophagy. Chloroquine is used to prevent or treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. Antiprotozoal-Malaria /Mechanism of action/ may be based on ability of chloroquine to bind and alter the properties of DNA. Chloroquine also is taken up into the acidic food vacuoles of the parasite in the erythrocyte.

    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.

  6. 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.

    THE MECHANISM OF ACTION OF CHLOROQUINE There are almost as many different proposals to explain why chloroquine exerts a specific antimalarial activity as there are congeners of the parent compound synthesized in an attempt to improve its efficacy. 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. 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.
