Note: based on a RGCC chemosensitivity analysis I have seen at a German clinic, Hydroxychloroquine has been effective in killing the cancer cells of 5 out 7 patients that were tested. It is one of very few available drugs that inhibits autophagy, a mechanism associated with its anticancer properties. Chloroquine mexico Plaquenil and wine Plaquenil patient education Plaquenil and dental implants Hydroxychloroquine is weakly basic, which permits its uptake and concentration in a nonionised form within cells. Having entered the lysosomes inside the cell, the acidic environment traps and concentrates the drug in its ionised state. Macrophages depend on acid proteases in their lysosomes for digestion of phagocytosed protein. This phase 0 trial studies hydroxychloroquine in blocking autophagy in patients with prostate cancer who are undergoing surgery or active surveillance. Autophagy is a process in which cells break down some parts of themselves to stay alive during times of stress, such as starvation. This may allow cancer cells to survive damage from chemotherapy. Cimetidine Moderate Avoid concomitant use of hydroxychloroquine and cimetidine as cimetidine may inhibit the metabolism of hydroxychloroquine as observed with the structurally similar chloroquine. However, the mechanism of inhibition of chloroquine metabolism appears to be via CYP inhibition, and hydroxychloroquine is not a known CYP substrate; cimetidine inhibition of hydroxychloroquine metabolism has not been demonstrated. In cancer, authophagy is the process used by cancer cells to “self-eat” in order to survive. Specifically, if authophagy is prolonged this will become a lethal process to cancer. duing chemotheraphy, radiotheraphy, etc.) authophagy is used by cancer cells to survive. However, note that Chloroquine has other properties as well that may be very well related to anti cancer mechanism, such as zinc ionophore, and others (see below the section on mechanisms). Hydroxychloroquine lysosome blocker New insights on the antiviral effects of chloroquine against., Hydroxychloroquine in Blocking Autophagy in Patients With. Plaquenil dosage for lichen planopilarisHydroxychloroquine in pregnancy and lactationAmerican academy of ophthalmology plaquenil guidelines 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. Chloroquine for research Cell-culture tested InvivoGen.

Oct 15, 2012 Hydroxychloroquine HCQ is a 4-aminoquinoline which differs from chloroquine CQ in the addition of a hydroxyl group. Initially used as antimalarials, both drugs have now become mainstays in the management of rheumatic diseases principally systemic lupus erythematosus SLE and rheumatoid arthritis RA. Drug Interactions With Hydroxychloroquine Certain parasite medications and beta blockers may cause potentially negative drug interactions with hydroxychloroquine. Some interactions can increase your risk of developing side effects, while others can reduce the effectiveness of the medications.
