    Employ the developed method for analysis of chloroquine phosphate in pharmaceutical dosage forms, and to compare between the developed method and the official methods for analysis of chloroquine phosphate formulations. The zero order absorption and first derivative spectra were measured for chloroquine phosphate 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. Chloroquine phosphate CQP is chemically known as 7-chloro-4-4-diethylamino-1-methylbutyl amino-quinoline diphosphate. Its molecular formula is C 18 H 26 ClN 32H 3PO 4, with a molecular weight of 515.87. The structural formula is Cl N NH N CH3 CH3. 2 H 3PO 4 Physically, CQP is a white crystalline powder soluble in water; sparingly

    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.

    CHLOROQUINE is used to treat or prevent malaria infections. It is also used to treat amebiasis. The lowest GoodRx price for the most common version of chloroquine phosphate is around $23.11, 75% off the average retail price of $93.55. 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. Oct 01, 2018 The dosage of Chloroquine phosphate is often expressed in terms of equivalent Chloroquine base. Each 500 mg tablet of Chloroquine phosphate contains the equivalent of 300 mg Chloroquine base. In infants and children the dosage is preferably calculated by body weight.
