    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.

    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. Jun 23, 2014 Non aqueous titration 1. NON AQUEOUS TITRATION 2. INTRODUCTION • Non- aqueous titrations are the titrations in which weakly acidic or basic substances are carried out using nonaqueous solvents to get sharp end point. • The moisture content in nonaqueous titrations should not be more than 0.05%. Assay by Non-Aqueous Titrations. a Acidimetry in Non-aqueous Titrations—It can be further sub-divided into two heads, namely i Titration of primary, secondary and tertiary amines, and ii Titration of halogen acid salts of bases.

    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.

    In general, the concept of pH becomes a relative measurement in these samples. There are alternate buffers available, such as water- methanol and water-ethanol buffer systems as described by IUPAC6. A titration for acidity or basicity, rather than a pH measurement, may be appropriate for non-aqueous samples.

    Plaquenil Dosage Guide - In a small percentage of patients, side effects may require temporary reduction of the initial dosage. Maintenance adult dosage When a good response is obtained, the dosage may be reduced by 50 percent and continued at a maintenance level of 200 mg to 400 mg 155 to 310 mg base daily, administered as a single daily dose or in two divided doses.
