UV-Visible spectrophotometry of Repaglinide in bulk and in formulation by using methyl orange as reagents
Two sensitive spectrophotometric methods are presented for the assay of Repaglinide in bulkdrug and in formulations using methyl orange, as reagents. Oxidant by reacting with a fixedamount of either methyl orange and measuring the absorbance at 485.2 nm (method-I) andmeasuring the absorbance at 618.9 nm (method-II). Developed method is based on the formationof extractable colored complex of dru...
متن کاملQuantitative estimation of diacerein in bulk and in capsule formulation using hydrotropic solubilizing agents by UV-spectrophotometry and the first order derivative using the area under curve method
PURPOSE This study was designed to develop and validate two simple, rapid, and economical UV-spectrophotometric and the first-order derivative methods using the area under curve method for estimation of diacerein in bulk and in capsule formulation. MATERIALS AND METHODS In this study, hydrotrophic solution of 8 M urea and 0.5 M potassium citrate were employed as the solubilizing agent to solu...

متن کاملEstimation of Naratriptan Hydrochloride in Bulk and Formulation by First Order Derivative UV- Spectrophotometric Methods
Naratriptan Hydrochloride is a triptan drug used for the treatment of migraine headaches and is a selective 5-hydroxytryptamine 1 receptor subtype agonist. Two simple, precise and economical UV-Spectrophotometric methods have been developed for the determination of Naratriptan Hydrochloride in pharmaceutical dosage form. In Method I, zero order spectrum of Naratriptan Hydrochloride was derivati...
