Simultaneous spectrophotometric determination of lidocaine and hydrocortisone acetate in pharmaceutical preparations by multivariate calibration methods
The multivariate calibration method, partial least square regression (PLS) was applied for thesimultaneous spectrophotometric determination of Lidocaine (LID) and Hydrocortisone acetate(HCA) in their mixtures. The parameters of chemometric technique were optimized and theproposed method was validated with synthetic samples and applied to analyze these drugs inpharmaceutical products with good a...
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 کاملSimultaneous estimation of amlodipine besylate and nebivolol hydrochloride in pharmaceutical tablets formulation by RP-HPLC using PDA detector
Background: The present work was undertaken with the aim to develop and validate a rapid and consistent RP-HPLC method in which the peaks will be appear with short period of time as per ICH Guidelines. Materials and Methods: The separation was achieved on a a stainless steel analytical column, Eclipse XDB plus C18 column (4.6 X 150 mm; 5 μm) in an isocratic mode. The mobile phase w...
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 کاملSimultaneous Determination of Amlodipine Besylate and Atorvastatin Calcium in Binary Mixture by Spectrofluorimetry and HPLC Coupled with Fluorescence Detection
Caduet tablets are novel prescription drug that combines amlodipine besylate (AM) with atorvastatin calcium (AT). A spectrofluorimetric and an HPLC-fluorescence detection methods were developed for simultaneous determination of both drugs in tablets. In the spectrofluorimetric method, native fluorescence of AM and AT were measured in methanol at 442 and 369 nm upon excitation at 361 and 274 nm,...
