Direct Spectrophotometric Determination of Glimepiride in Pure Form And Pharmaceutical Formulations Using Bromocresol Purple

Spectrophotometric determination of etodolac in pure form and pharmaceutical formulations

BACKGROUND Etodolac (ETD) is a non-steroidal anti-inflamatory antirheumatic drug. A survey of the literature reveals that there is no method available for the determination of ETD in pure form and pharmaceutical formulations by oxidation-reduction reactions. RESULTS We describe three simple, sensitive and reproducible spectrophotometric assays (A-C) for the determination of etodolac in pure f...

Two new, simple, rapid and reproducible spectrophotometric methods have been developed for the determination of lamotrigine (LMT) both in pure form and in its tablets. The first method (method A) is based on the formation of a colored ion-pair complex (1:1 drug/dye) of LMT with bromocresol green (BCG) at pH 5.02±0.01 and extraction of the complex into dichloromethane followed by the measurement...

New Method for Spectrophotometric Determination of Lisinopril in Pure Form and in Pharmaceutical Formulations

Synthesis new organic azo dye as reagent 3-((4-acetyl-3-hydroxyphenyl) diazenyl)-4-amino-N-(5-methylisoxazol3-yl)benzene sulfonamide (SDA) and Analytical Study of Co(II), Ni(II) and Cu(II), metals complexes. The reagent and its complexes were characterized by elemental analysis, UV-Vis, and molar conductivity measurements. The data show that the complexes have the composition of [MR]X2 type. Th...

Spectrophotometric determination of certain cephalosporins in pure form and in pharmaceutical formulations.

A simple and reproducible spectrophotometeric method for the assay of cefotaxime sodium, cefuroxime sodium, and ceftriaxone disodium with metol-chromium(VI) reagent has been developed. The procedure is based on direct oxidation of metol by potassium dichromate in presence of drug in acidic medium and subsequent formation of ternary complex. Beer's law is obeyed in the range 0.2-28 microg ml(-1)...
