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. Mechanism of action of hydroxychloroquine in diabetes Hydroxychloroquine hydroxyzine interaxtion Chloroquine injection for malaria treatment Hydroxychloroquine how often eye exam 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. A comprehensive stability-indicating HPLC method for determination of chloroquine in active pharmaceutical ingredient and tablets Identification of oxidation impurities Author links open overlay panel Ana Silva Coelho a Clara Elisa Pontes Chagas a Rodrigo Maia de Pádua b Gerson Antônio Pianetti a Christian Fernandes a The focus of this study is identification and characterization of major unknown impurities in chloroquine CQ and hydroxychloroquine HCQ bulk drug samples using liquid chromatography/ion trap mass spectrometry LC/IT/MS and liquid chromatography/time of flight mass spectrometry LC/TOF/MS.
