Visible Spectrophotometric Estimation of Diacerein in Bulk and Pharmaceutical Dosage Forms
Two simple, sensitive, accurate, rapid, and economical spectrophotometric methods have been developed for the estimation of diacerein in Pharmaceutical dosage forms. Method A is based on the reaction of diacerein with Folin-Ciocalteu reagent, in the presence of 0.5 N sodium hydroxide solution, giving a pink-colored chromogen, which shows maximum absorbance at 512 nm against reagent blank, while...
متن کاملDetermination of Josamycin and Ciprofloxacin in their Pharmaceutical Dosage Forms by Spectrophotometry
Josamycin is a macrolide antibiotic that is particularly indicated for the treatment of infections of the skin, respiratory tract, ear, nose and throat. Its important pharmacokinetic properties include accumulation in certain cells and an increase in blood plasma levels after repeated ingestion. It also used as an alternative to penicillin-allergic patients. Like other macrolide antibiotics, jo...
متن کاملDerivative Spectrophotometry for Simultaneous Analysis of Chlorpheniramine Maleate, Phenylephrine HCl, and Phenylpropanolamine HCl in Ternary Mixtures and Pharmaceutical Dosage Forms
In this study, different derivative spectrophotometric methods are proposed for the simultaneous determination of chlorpheniramine maleate (CP), phenylephrine HCl (PE) and phenylpropanolamine HCl (PP) in their ternary mixtures and in pharmaceutical dosage forms. Spectra of single component and ternary mixtures of various concentrations and combinations from zero- to fourth-derivation were obtai...

متن کاملDETERMINATION OF AMOXYCYLLIN AND CLAVULANIC ACID IN PHARMACEUTICAL DOSAGE FORMS BY HPLC WITH AMPEROMETRIC DETECTION
A simple and sensitive high performance liquid chromatographic method with electrochemical detection is described for the quantitative determination of the amoxycillin and clavulanic acid in pharmaceutical dosage forms. Separation of sample components occurs on a reversed phase C18 column with a mobile phase consisting of methanol-water-phosphate buffer. For the amperometric detection, the pote...
