Spectrophotometric and spectrofluorimetric determination of trimebutine

Spectrofluorimetric, Atomic Absorption Spectrometric and Spectrophotometric Determination of Some Fluoroquinolones

Simple, accurate, sensitive and selective spectrofluorimetric, atomic absorption spectrometric and spectrophotometric methods are described for the quantitative determination of ten fluoroquinolones (amifloxacin, ciprofloxacin hydrochloride, difloxacin hydrochloride, enoxacin, enrofloxacin, lomefloxacin hydrochloride, levofloxacin, norfloxacin, ofloxacin and pefloxacin mesylate). The first meth...

Spectrophotometric Determination of Trimebutine Through Ion- Pair and Charge- Transfer Complexation Reactions

Development and validation of spectrophotometric and spectrofluorimetric methods for simultaneous determination of Tofisopam

Two simple, rapid and accurate spectrophotometric and spectrofluorimetric methods developed for the determination of Tofisopam (TF) in pure form and in pharmaceutical formulation. The spectrophotometric method (A) is based on the reduction of ferric into ferrous in presence of 1, 10-phenanthroline to give an orange –red colored ferroin complex measured at 510 nm. Method (B) spectrofluorimetric ...

Spectrofluorimetric and Spectrophotometric Determination of Pregabalin in Capsules and Urine Samples

Three new, simple, sensitive and selective spectrofluorimetric and spectrophotometric methods were developed for the determination of the γ-amino-n-butyric acid derivative, pregabalin. Pregabalin as a primary amine reacts with fluorescamine to yield a fluorescent product (Method I), with 2,4-dinitrofluorobenzene (Method II) and 2,3,5,6-tetrachloro-1,4-benzoquinone (Method III) in aqueous alkali...

New Spectrophotometric and Spectrofluorimetric Methods for Determination of Prazosin HCl in API and Drug Product

New simple and sensitive spectrophotometric and fluorimetric methods have been developed for the determination of prazosin hydrochloride (PRZ) in its active pharmaceutical ingredient (API) and drug product. The spectrophotometric method (Method I) is based on formation of a binary complex with rose Bengal (RB) at 572 nm. The absorbance-concentration plot is rectilinear over the range 2.5 25 μg/...
