Extractive spectrophotometric determination of ambrisentan.
PURPOSE Ambrisentan (ABS) is an antihypertensive drug used in the treatment of pulmonary atrial hypertension. The survey of literature for ABS revealed only two spectrophotometric methods for its quantification. The reported methods lack the sensitivity. This study is aimed at developing two sensitive extractive spectrophotometric methods for the determination of ABS in bulk and in tablets. M...
متن کاملExtractive spectrophotometric determination of levetiracetam in pharmaceutical formulations
Three simple, economical, precise, reliable and reproducible visible spectrophotometric methods (A, B and C) have been developed for the estimation of Levetiracetam in bulk as well as in Tablet formulation. The developed methods A, B and C are based on the formation of chloroform extractable complex of Levetiracetam with Bromocresol green (method A), Bromophenol blue (method B) and Bromothymol ...
متن کاملExtractive Spectrophotometric Method for Determination of Carvedilol in Tablets
A sensitive and rapid extractive spectrophotometer method has been developed for the assay of carvedilol in pharmaceutical formulations. The method is based on the formation of a chloroform soluble ion-pair complex between carvedilol and bromocresol green in an acidic medium. The complex shows absorption maximum at 415 nm and the system obeys Beer’s law in the concentration range of 5-25 μg/ml....
متن کاملExtractive Spectrophotometric Determination of Mirtazapine in Pure and Pharmaceutical Forms
Four simple and sensitive extractive spectrophotometric methods have been described for the assay of Mirtazapine either in pure form or in pharmaceutical formulations. The developed methods involve formation of coloured chloroform extractable ion-pair complexes of the drug with bromocresol green (BCG), bromophenol blue (BPB), bromothymol blue (BTB) and bromocresol purple (BCP) in acidic medium....
متن کاملExtractive Spectrophotometric Method for the Determination of Tropicamide
Two simple, rapid, and extractive spectrophotometric methods were developed for the determination of tropicamide (TPC). These methods are based on the formation of ionpair complexes between the basic nitrogen of the drug with bromocresol purple (BCP) and methyl orange (MO) in acidic buffer solution. The formed complexes were extracted with chloroform and measured at 408 and 427 nm using BCP and...
