    Process related impurities in chloroquine and hydroxychloroquine


    The methods of quantification of HCQ sulfate, despite the undeniable advantages, have certain limitations, such as high cost of operation and maintenance of equipment, sample processing and analysis of the results relatively complicated. However, the simplicity of the process and velocity of the spectrophotometry by absorption in the UV -Vis region corroborate the usefulness of this methodology.

    Hydroxychloroquine HCQ, sold under the brand name Plaquenil among others, is a medication used for the prevention and treatment of certain types of malaria. Specifically it is used for chloroquine -sensitive malaria. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. Related Products. Hydroxychloroquine - Impurity D. Hydroxychloroquine Freebase - Impurity C. Hydroxychloroquine O-Acetate. Hydroxychloroquine - Impurity E. Chloroquine CQ is used to prevent and treat malaria and amebiasis,1 while hydroxychloroquine HCQ, a less toxic metabolite of chloroquine, is used to treat rheumatic diseases such as systemic lupus erythematosus SLE, rheumatoid arthritis RA, juvenile idiopathic arthritis JIA and Sjogren's syndrome.2

    The method was developed from the sample preparation used in the determination of HCQ in dosage form according to the methodology described by the USP 36. This work describes the application of Qb D in the development, optimization, and validation of an analytical method by absorption spectrophotometry in the UV-Vis region for quantification of HCQ sulfate.

    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. In cancer, authophagy is the process used by cancer cells to “self-eat” in order to survive. This is why authophagy can be both good and bad.

    Hydroxychloroquine-induced toxic hepatitis in a patient with. Liver enzyme abnormality was defined as a 10-fold or greater increase in aspartate aminotransferase and alanine aminotransferase. Acute toxic hepatitis was diagnosed, which rapidly returned to normal after cessation of the suspected causative medication, hydroxychloroquine, and subsequent administration of mycophenolate mofetil.
