    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.

    Dissolve a quantity of the substance being examined to give an expected titration volume of between 70–90% of the burette volume, in 50 mL of dehydrated ethanol R and 5.0 mL of hydrochloric acid 0.01 mol/L VS. Carry out a potentiometric titration 2.6. Non-aqueous titration 2017-01 Page 1 of 2 The International Pharmacopoeia - Ninth Edition. Lithium chloride in non-aqueous potentiometric titrations Received 26 March 1960 INSTRUMENT instability is often a problem iu the use of non-aqueous solvents in potentiometric measurements or titrations. Nonaqueous titration is the titration of substances dissolved in nonaqueous solvents. 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 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.

    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.
