    Chloroquine stability in water


    The effects of light at wavelengths of 240–600 nm on solutions of chloroquine in isopropanol, and of light at wavelenghts of 320–600 nm on solutions of chloroquine in buffer solutions were investigated. Chloroquine has long been used in the treatment or prevention of malaria from Plasmodium vivax, P. malariae, excluding the malaria parasite Plasmodium falciparum, for it started to develop widespread resistance to it.

IV, Photochemical degradation of chloroquine Karin Nord, Jan Karlsen and Hanne Hjorth Tnesen Institute of Pharmacy, Department of. 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. The solubilities of chloroquine diphosphate and 4,7-dichloroquinoline in water, ethanol, tetrahydrofuran, acetone, and acetonitrile were measured over the temperature range of 298.2 to 333.2 K.

    It is recommended to check if chloroquine is still effective in the region prior to using it. Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance.

    E-pH stability diagram of water at 25 o C. Below the equilibrium reaction shown as line a in this figure, the decomposition of H 2 O into hydrogen is favored while it is thermodynamically stable above the same line a. As potential becomes more positive or noble, water can be decomposed into its other constituent, oxygen, as illustrated in. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Chloroquine is a member of the drug class 4-aminoquinoline. Samples of different dosage forms of chloroquine phosphate, that covered the 23 excipents used in chloroquine phosphate formulation were analyzed by dissolving a quantity equivalent to 100 mg of chloroquine phosphate of each formulation in 100 ml of water, 5 ml of this solution was diluted to 100 ml with water, the
