It may have both an anti-spirochaete activity and an anti-inflammatory activity, similar to the treatment of rheumatoid arthritis. And caution is required if patients have certain heart conditions, diabetes, psoriasis etc. What class of drug is chloroquine Chloroquine injection dosage for adults The antimalarial chloroquine CQ has shown early promise among these. Due to its basic pKa, CQ preferentially accumulates within cellular lysosomes, subsequently. Chloroquine is a lysosomotropic agent that prevents endosomal acidification 1. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes. In this video, I will explain into one of the main antimalarial drug, chloroquine. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive. For prolonged treatment of lupus or arthritis, adverse effects include the acute symptoms, plus altered eye pigmentation, acne, anaemia, bleaching of hair, blisters in mouth and eyes, blood disorders, convulsions, vision difficulties, diminished reflexes, emotional changes, excessive coloring of the skin, hearing loss, hives, itching, liver problems or liver failure, loss of hair, muscle paralysis, weakness or atrophy, nightmares, psoriasis, reading difficulties, tinnitus, skin inflammation and scaling, skin rash, vertigo, weight loss, and occasionally urinary incontinence. The most common adverse effects are a mild nausea and occasional stomach cramps with mild diarrhea. For short-term treatment of acute malaria, adverse effects can include abdominal cramps, diarrhea, heart problems, reduced appetite, headache, nausea and vomiting.

These are identified as chloroquine-dilated lysosomes and lipid bodies with LAMP-2 and LipidTOX co-localization, respectively. Dilation is an indicator of lysosomal dysfunction. Chloroquine treatment of ARPE-19 cells. - PubMed Central PMC. Antimalarial Drug Mechanism of Action What is Chloroquine.. Chloroquine Indications, Side Effects, Warnings -. An aminoquinoline that is quinoline which is substituted at position 4 by a 5-diethylaminopentan-2-ylamino group at at position 7 by chlorine. Chloroquine is a chemotherapeutic agent for the clinical treatment of malaria. Chloroquine is able to bind to DNA, and inhibit DNA replication and RNA synthesis which in turn results in cell death. The effect of Chloroquine may also be related to the formation of a toxic heme-Chloroquine complex. Nov 15, 2015 Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4. Trapped as cationic species in the acidic organelles owing to his basic pKa, thereby elevating the endosomal pH 48.
