Spectrophotometric Analysis of Vardenafil in Tablet Dosage Forms by Using Electrophilic Coupling Reagents
Two new spectrophotometric methods (M1 and M2) are developed for the determination of vardenafil in bulk and in tablet dosage forms. The method M1 involves oxidative coupling of vardenafil with 3-methyl-2-benzothiazolinone hydrazone hydrochloride in presence of ferric chloride in acidic medium yielding green colored chromogen with absorption maxima at 625 nm. The method M2 is based on the oxida...
متن کاملApplication of hydrotropic solubilization in spectrophotometric analysis of Esomeprazole and Itopride pharmaceutical combined tablet dosage forms
Two simple, accurate and precise methods for simultaneous estimation of Esomeprazole and Itopride in bulk drug and tablet dosage form have been described. Method-A employs formation and solving of simultaneous equation using 231 and 370 nm as two analytical wavelengths. Method -B is Absorption ratio method, which uses 308 and 331 nm as two analytical wavelengths.Beer’s law was obeyed in the con...
