Optimized and validated flow-injection spectrophotometric analysis of topiramate, piracetam and levetiracetam in pharmaceutical formulations.
Application of a sensitive and rapid flow injection analysis (FIA) method for determination of topiramate, piracetam, and levetiracetam in pharmaceutical formulations has been investigated. The method is based on the reaction with ortho-phtalaldehyde and 2-mercaptoethanol in a basic buffer and measurement of absorbance at 295 nm under flow conditions. Variables affecting the determination such ...
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 کاملSpectrophotometric Determination of Tropicamide in Bulk and Pharmaceutical Formulations
A simple and sensitive extractive spectrophotometric method is described for determination of tropicamide. The method is based on the reaction of tropicamide and bromocresol green. The ion-paired colored complex was extracted with chloroform at pH 3. The extracted complex showed maximum absorbance at 423 nm. The complex was stable up to 2 days and obeyed Beer's law over the concentration r...
متن کاملIndirect flow-injection spectrophotometric determination of meloxicam, tenoxicam and piroxicam in pharmaceutical formulations.
A simple and sensitive indirect spectrophotometric method for the assay of meloxicam (MX), tenoxicam (TX) and piroxicam (PX) in pure and in pharmaceutical formulations by flow injection analysis (FIA) has been proposed. The method is based on the oxidation of these drugs by a known excess of N-bromosuccinimide (NBS) in an acidic medium, followed by a reaction of excess oxidant with chloranilic ...
