One titrimetric and two spectrophotometric methods are proposed for the determination of diethylcarbamazine citrate (DEC) in bulk drug and in formulations using potassium iodate and potassium iodide as reagent. The methods employ the well-known analytical reaction between iodate and iodide in the presence of acid. In titrimetry (method A), the drug was(More)
Two simple titrimetric methods are described for the determination of pheniramine maleate (PAM) in pure form and in its dosage forms. The principle involved in the methods are simple acid-base reaction in which the carboxylic acid group of the drug was determined by titrating with an aqueous NaOH solution either visually using phenolphthalein as indicator(More)
Two simple and selective spectrophotometric methods are described for the determination of trifluoperazine dihydrochloride (TFH) as base form (TFP) in bulk drug, and in tablets. The methods are based on the molecular charge-transfer complexation of trifluoperazine base (TFP) with either 2,4,6-trinitrophenol (picric acid; PA) or 2,4-dinitrophenol (DNP). The(More)

Three indirect methods for the assay of flunarizine dihydrochloride (FNH) in bulk drug and commercial formulation based on titrimetric and spectrophotometric techniques using bromate-bromide mixture are described. In titrimetry, a measured excess of bromate-bromide mixture is added to an acidified solution of FNH and the unreacted bromine is determined(More)
One titrimetric and two spectrophotometric methods are described for the determination of ketotifen fumarate (KTF) in bulk drug and in tablets using cerium(IV) as the oxidimetric agent. In titrimetry (method A), the drug was treated with a measured excess of cerium(IV) in H2SO4 medium and after a standing time of 10 min, the surplus oxidant was determined(More)
