    Non aqueous titration of chloroquine phosphate


    All the indicators except the three and four-membered-ring cyclic ethers give sharp end-point inflections in titrations of quinuclidine and 8-hydroxyquinoline, but for caffeine only the acetal indicators are satisfactory. Relative standard deviations obtained in replicate determinations of 0.1-mequiv.

Take this medication by mouth, usually with food to prevent stomach upset, exactly as directed by your doctor. Daily or weekly dosing, dosage amount, and length. The accuracy, as seen in or estimated from the percent recovery studies, was between 96 and 99% with an average of 97.75% in biological materials, common excipients and sampled tablets. Non- aqueous titration was employed as a parallel validation procedure of the described method.

    In the drug titrations, the acetal indicators give the sharpest end-point inflections for chloroquine phosphate. Amounts range from 0.10 to 0.66%, with sample and titrant delivery errors making a significant contribution.
