Spectrophotometric and titrimetric methods for the determination of nordiazepam in pure and pharmaceutical dosage form

Titrimetric and Spectrophotometric Methods for the Determination of β-blockers in Pharmaceutical Dosage Form

Three new methods using titrimetric and spectrophotometry are described for the determination of Propranolol Hydrochloride (PPH) and Atenolol (AN) with potassium bromate as the oxidimetric reagent and acid dyes, Methyl orange and Indigo carmine. In direct titrimetric (method A), the drug is titrated directly with bromate in acid medium and in the presence of excess of bromide using methyl orang...

Reverse Phase HPLC and Visible Spectrophotometric Methods for the Determination of Meropenem in Pure and Pharmaceutical Dosage Form

In the present investigation a reverse phase high performance liquid chromatographic method and a visible spectrophotometric method were developed for the quantitative determination of meropenem, a highly active antibiotic in powder for injection. The chromatographic analysis was carried out by reversed phase technique on an ultra sphere XL-ODS, 75mm x 4.6mm I.D.,5μm column with a mobile phase ...

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...
