    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.

    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. The latter is related to drug accumulation in melanin-rich tissues. 15,16 Prolonged treatment with chloroquine also can cause toxic myopathy, cardiopathy, and peripheral neuropathy and neuropsychiatric disturbances; all of these reactions improve if the drug is discontinued promptly. 17,18 Both chloroquine and hydroxychloroquine should be used cautiously in the presence of hepatic or severe gastrointestinal tract disease, neurological disorders, and blood disorders. For patients receiving. A metabolite of chloroquinehydroxychloroquine – has a long half-life 32–56 days in blood and a large volume of distribution 580–815 L/kg. The therapeutic, toxic and lethal ranges are usually considered to be 0.03 to 15 mg/l, 3.0 to 26 mg/l and 20 to 104 mg/l, respectively.

    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.
