Tell your doctor and pharmacist about all of your drugs (prescription or OTC, natural products, vitamins) and health problems. You must check to make sure that it is safe for you to take chloroquine with all of your drugs and health problems. How does plaquenil work for lupus Hydroxychloroquine and antacids 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. Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion. Autophagy has recently been demonstrated as important for conferring resistance to chemotherapy, radiation therapy and immunotherapy. Compounds are now available that can reverse autophagy, including the antimalarial compounds chloroquine and hydroxychloroquine, as well as the antidepressant agent clomipramine. For all uses of chloroquine: WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Do not start, stop, or change the dose of any drug without checking with your doctor. Chloroquine and autophagy Chloroquine - FDA prescribing information, side effects., Chloroquine - Wikipedia Hydroxychloroquine and liverWhat is hydroxychloroquine sulphate used for Autophagy is a key pathway in the development of endocrine resistance in breast cancer, and targeting autophagy can reverse antiestrogen resistance. Chloroquine, an anti-malarial drug, inhibits autophagy by preventing degradation of autolysosomes. Hydroxychloroquine inhibits autophagy. - PubMed Central PMC. Autophagy and Lymphoma. Inhibition of autophagy with bafilomycin and chloroquine.. Autophagy was hypothesized to be a key underlying cellular process in these dysfunctions. We conjectured that rapamycin RAPA and chloroquine CQ, as two autophagy-modifying agents, regulate the autophagy process and may produce deleterious or beneficial effects on intestinal health and growth. Abstract. Objective We attempt to investigate the mechanism triggered by Chloroquine CQ and its association with autophagic function. Methods To investigate the CQ effects on non-malignant and malignant cells, we performed cell viability assays, flow cytometry analysis, immunoblotting, immunofluorescence, confocal microscopy, electronic microscopy and Fluorescence Lifetime Imaging. Autophagy is a homeostatic cellular recycling system that is responsible for degrading damaged or unnecessary cellular organelles and proteins. Cancer cells are thought to use autophagy as a source of energy in the unfavorable metastatic environment, and a number of clinical trials are now revealing the promising role of chloroquine, an autophagy inhibitor, as a novel antitumor drug.
