    Assay— Dissolve about 100mg of Chloroquine Phosphate,accurately weighed,in about 5mLof water,and dilute quantitatively and stepwise with dilute hydrochloric acid 1in 1000to obtain a solution containing about 10µg per mL. Similarly prepare a Standard solution of USP Chloroquine Phosphate RS. Concomitantly determine the absorbances of both solutions in 1-cm cells at the wavelength of maximum. The dose of chloroquine is often expressed or calculated as the base each 500 mg tablet of chloroquine phosphate is equivalent to 300 mg chloroquine base. -The pediatric dose should never exceed the adult dose. Standard solutionUSP Chloroquine Phosphate RS in tion of about 1.5µg per mL. Medium Test solution—Proceed as directed for Assay preparation in Sample solutionDilute with Medium to a concentrationthe Assay. that is similar to the Standard solution. TolerancesNLT 75% Q of the labeled amount of Procedure—Separately inject equal volumes about 20µL

    Add 8 ml of 5M Sodium Hydroxide Take sample equivalent to 200 mg of Calcium Pantothenate in a 250 ml titration flask. Then dilute with water to 150ml, add 15ml of 1N sodium hydroxide and 3-5 mg of Hydroxy naphthol blue as indicator and titrate with 0.05M Edetatedisodium VS until the solution is deep blue.1 ml 0.05M Edetate disodium Dissolve a quantity of the powder containing 0.300 g of Calcium Lactate Pentahydrate in 50 ml of water and titrate with 0.05 M Disodium Edetate VS to within a few milliliters of the expected end point.

The zero order absorption and first derivative spectra were measured for chloroquine phosphate In most cases, 250 mg tablets have an equivalence of 150 mg chloroquine base, and 500 mg tablets have an equivalence of 300 mg chloroquine base. Although the purity mentioned above is generally accurate, it would be best to verify the chloroquine base contained in the tablets of your choice in order to be able to properly calculate the exact dosage.
