    Assay of chloroquine by non aqueous titration


    It is the most common titrimetric procedure used in pharmacopoeial assays and serves a double purpose: it is suitable for the titration of very weak acids and very weak bases, and it provides a solvent in which organic compounds are soluble. The most commonly used procedure is the titration of organic bases with perchloric acid in anhydrous acetic acid.

    Titrimetric Assay Assay of diclofenac by non-aqueous titration Titre values Table 1 for sample A and the calculation for percent purity are shown below as an example. Samples B to F were similarly treated. The average titre values of 0.1M HClO 4 after titrations for samples A to F, the amount of diclofenac in the sample, percent purity Non Aqueous Titration Theory. The need for non aqueous titration arises because water can behave as a weak base and a weak acid as well, and can hence compete in proton acceptance or proton donation with other weak acids and bases dissolved in it. A potentiometric titration method in non-aqueous media is proposed for the determination of some commonly used anti-inflammatory agents. The direct potentiometric titration of three anti-inflammatory agents, namely mefenamic acid, fenbufen and ibuprofen; and the indirect potentiometric titration of diclofenac sodium was carried out in acetonitrile solvent using tetra-n-butylammonium hydroxide.

    The Karl Fischer titration for water content is another nonaqueous titration, usually done in methanol or sometimes in ethanol. These assays sometimes take some perfecting in terms of being able to judge the endpoint precisely.

    Reported for the assay of CQP in dosage forms. An acid-base titrimetric method was developed, where the drug was titrated with 0.1 M NaOH in MeCN H2O medium using thymol blue as indicator 4. A non-aqueous titrimetric method involoving conductometric titration of drug with HClO 4 has also been reported 5. Gravimetric 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. The feasibility of a titration in a given sol- vent can be calculated from. Abstract A non-aqueous titration method was developed to assay the insensitive.

    Hydroxychloroquine and Chloroquine Retinopathy. First present as pericentral retinopathy and thus requires monitoring outside the macula. We assume chloroquine retinopathy follows a similar course as hydroxychloroquine retinopathy and so these guidelines also apply to patients taking chloroquine therapy.
