A photometric titration procedure is described for the determination of a number of phenothiazine derivatives and their dosage forms. An acidic solution of the drug or dosage form is titrated with standard ceric sulfate solution. The end point is determined photometrically at 420 mG. Quantitative re
Barbiturate salts in various dosage forms are determined by liberating the barbituric acid from the salt by passage through a cation exchange resin. Dimethylformamide is used as the solvent. The barbituric acid is titrated visually with 0.1 N sodium methoxide in benzene-methanol. The method is rapid
The difference in pKa values for acetaminophen and the barbituric acids permits differentiation of mixtures containing these drugs. Ion-exchange chromatography is used t o separate acetaminophen and barbiturate from other active and inert constituents. Titrations are performed nonaqueously in dimeth
