    Non aqueous titration of chloroquine

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

    Pharmacopeia USP 3. BP describes non-aqueous titration with perchloric acid as titrant where the end point is located potentiometrically. USP describes a UV-spectrophotometric method, where the absorbance of CQP in HCl medium is measured at 343 nm. Feb 09, 2017 Nonaqueous titration is the titration of substances dissolved in solvents other than water. It is the most common titrimetric procedure used in pharmacopoeia. Skip navigation Thus the choice of the appropriate medium and titrant permits the determination of a variety of such materials by non-aqueous titration. Further, depending upon which part of a compound is physiologically active, it is often possible to titrate that part by proper selection of solvent and titrant.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

The nonaqueous titrimetric method was applied as parallel validation estimation. This involves volumetric determination of the chloroquine in non- aqueous solvent using 0.1M perchloric acid and crystal violet as indicator. Non-Aqueous Titrimetric Assay for Determination of Loratadine in Pharmaceutical Preparations. Non-aqueous titrations is the most titrimetric procedure used in pharmacopoeial assays and serves a double purpose, as it suitable for the titration of weak acids and bases and provides a solvent in which organic compounds are soluble.

    Chloroquine C18H26ClN3 - PubChem Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin.
