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. Synthesis of chloroquine phosphate slideshare Hydroxychloroquine 200 mg ingredients An important mode of action of chloroquine and hydroxychloroquine is the interference of lysosomal activity and autophagy. Hours ago And there are almost certainly several modes of action at work, which will go on to have different effects in different human tissues, etc. Both chloroquine and hydroxychloroquine are used. Mice infected with P. berghei were given 50 mgm./kgm. chloroquine intra-peritoneally; rats infected with P. berghei were given 95 mgm./kgm. and monkeys with P. cynomolgi 17 mgm./kgm. These are moderately effective doses. Samples of blood were fixed in glutaraldehyde and osmic acid and sections were studied by the electron microscope. During the first 2 hours after treatment the pigment and. 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.

Quinoline-containing drugs such as chloroquine and quinine have had a long and successful history in antimalarial chemotherapy. Chloroquine and hydroxychloroquine increase pH within intracellular vacuoles and alter processes such as protein degradation by acidic hydrolases in the lysosome, assembly of macromolecules in the endosomes, and posttranslation modification of proteins in the Golgi apparatus. A brief presentation of chloroquine, its history and its future in the medical industry. Mechanism of Action of Fluoroquinolones - Duration. Elsevier India 9,452 views.
