Spectrophotometric Determination of Ceftibuten in Bulk and in Pharmaceutical Formulations

Abstract

A simple and cost effective spectrophotometric method is described for the determination of ceftibuten in pure form and in pharmaceutical formulations. The method is based on the formation of blue colored chromogen, when the drug reacts with Folin-Ciocalteu (F-C) reagent in alkaline medium. The colored species has an absorption maximum at 798 nm and obeys Beer’s law in the concentration range 10-50 mcg/mL. The apparent molar absorptivity and sandell’s sensitivity were 0.4583x104and 0.3x104respectively. The slope and intercept of the equation of the regression line are 4.5x10-3and 1.3x10-5respectively. The optimum experimental parameters for the reaction have been studied and the validity of the described procedure was assessed. Statistical analysis of the results has been carried out revealing high accuracy and good precision. The proposed method was successfully applied for the determination of ceftibuten in pharmaceutical formulations.

Spectrophotometric Method for Simultaneous Determination of Amiloride and Hydrochlorothiazide in Combined Dosage Form

“…It is frequently used alone or in combination with other medications for the treatment of hypertension, congestive heart failure, symptomatic edema, diabetes insipidus, renal tubular acidosis, hypoparathyroidism, and edema and prevention of kidney stones and used in the treatment of osteoporosis [5]. Literature survey reveals that AML is estimated individually by UV [6] and combine with HCZ forced degradation studies [7], RP-HPLC, Derivative Spectrophotometry [8][9][10] and HCZ combine with other drugs HPLC [11], UV and HPLC [12], HPLC-UV, LC-DAD and LC-MS [13] UPLC RP-UPLC [14,15] methods were reported. The purpose of this study was to develop simple, rapid, precise and accurate UV method for the simultaneous estimation of AML and HCZ in pure and in combined tablet dosage form by Simultaneous equation method and validate as per International Conference on Harmonization (ICH) guidelines.…”
