titrimetric and spectrophotometric methods for the determination of β-blockers in pharmaceutical dosage form

Titrimetric and Spectrophotometric Methods for the Determination of β-blockers in Pharmaceutical Dosage Form

Three new methods using titrimetric and spectrophotometry are described for the determination of Propranolol Hydrochloride (PPH) and Atenolol (AN) with potassium bromate as the oxidimetric reagent and acid dyes, Methyl orange and Indigo carmine. In direct titrimetric (method A), the drug is titrated directly with bromate in acid medium and in the presence of excess of bromide using methyl orang...

Spectrophotometric Methods for Determination of Sunitinib in Pharmaceutical Dosage Forms Based on Ion-pair Complex Formation

Three rapid spectrophotometric methods were developed for the determination of sunitinib based on the formation of ion-pair complex in acidic medium with bromocresol purple, bromothymol blue, and bromophenol blue. The formed ion-pair complexes, extractable with chloroform, were measured at 422 nm for bromocresol purple, 425 nm for bromothymol blue and 427 nm for bromophenol blue. All these meth...

Validated UV spectrophotometric method for quantitative determination of Mirabegron in bulk and Pharmaceutical dosage form

In the present work simple, precise, specific, accurate and cost effective UV spectrophotometric method has been developed for the determination of Mirabegron in pure and pharmaceutical formulation. The wavelength of the Mirabegron detection was 251 nm using methanol as a solvent and obeys Beer’s law in the concentration range of 0.2 – 1.2 μg /mL with a correlation coefficient of 0.9991. Relati...
