Spectrophotometric Determination of drugs in bulk and pharmaceutical dosage forms by using Tetracyanoethylene
ABSTRACT A selective ,sensitive ,accurate UV-Visible spectrophotometric methods have been developed for the estimation of drugs viz.,Diflunisal (DFL),Febuxostat(FBT),Metaxalone(MTX),Fexofenadine methyl ester(FME) and Linezolid(LZD) in bulk and their pharmaceutical dosage forms using Tetracyanoethylene (TCNE) as analytical reagent. These method are based on the formation of charge transfer compl...
متن کاملSimultaneous Spectrophotometric Estimation of Atorvastatin Calcium and Amlodipine Besylate in Tablet Dosage Forms
A simple and economical dual wavelength spectrophotometric method has been developed for the simultaneous estimation of atorvastatin calcium and amlodipine besylate in their combined dosage forms. The method was based on property of additivity of absorbances. The two wavelengths on amlodipine besylate curve were found out where it showed same absorbance, which were 257.4 and 360.0 nm. At 360.0 ...
متن کاملKinetic spectrophotometric method for determination of amlodipine besylate in its pharmaceutical tablets
A simple and sensitive kinetic spectrophotometric method has been developed and validated for determination of amlodipine besylate (AML). The method was based on the condensation reaction of AML with 7-chloro-4-nitro-2,1,3-benzoxadiazole in an alkaline buffer (pH 8.6) producing a highly colored product. The color development was monitored spectrophometrically at the maximum absorption λmax 470 ...
متن کاملThree Multivariate Calibration Methods for Simultaneous Spectrophotometric Determination of Olmesartan Medoxamil, Amlodipine Besylate and Hydrochlorothiazide in Their Combined Dosage Form
Olmesartan medoxamil (OLM, an angiotensin II receptor blocker), amlodipine besylate (AML, a dihydropyridine calcium channel blocker) and hydrochlorothiazide (HCT, a diuretic of the class of benzothiadiazines) are co-formulated in a single-dose combination for the treatment of hypertensive patients whose blood pressure is not adequately controlled on either component monotherapy. In this work, t...
متن کاملA New Extractive Spectrophotometric Method for the Determination of Gatifloxacin and Cefotaxime Sodium in Pure and Pharmaceutical Dosage Forms
Simple, accurate, precise, and rapid extractive spectrophotometric method was developed for the estimation of gatifloxacin (I) and cefotaxime sodium (II) in both pure and pharmaceutical dosage forms. The method was based on the formation of colored complex by the drugs with Eriochrome black-T in an acidic medium. The ion-associated complex formed was quantitatively extracted under the experimen...
