A validated RP-HPLC method for the estimation of ornidazole in pharmaceutical dosage forms
(Hacettepe University, 2012)
A new, simple, rapid, selective, precise and accurate isocratic reverse phase high performance liquid chromatography assay has been developed and validated for assay of Ornidazole in tablet formulations. Tinidazole was ...
Optimization of separation of several sulfonamides in acetonitrile-water binary mixtures by using symmetry shield RP-8 column
(Hacettepe University, 2009)
In this work, the proportion of organic modifier of the hydro-organic mobile phase was optimized in order to separate twelve compounds namely sulfaguanidine, sulfanilamide, sulfadiazine, sulfathiazole, sulfamethazine, ...
Simultaneous estimation of ceftazidime and ceftizoxime in pharmaceutical formulations by HPLC method
(2011)
The aim of the present study was to develop a fast, sensitive and reliable method for rapid screening of cephalosporin injectable dosage forms namely ceftazidime and ceftizoxime to the detection of counterfeit and substandard ...
Determination of pK a values of cefdinir and cefixime by LC and spectrophotometric methods and their analysis in pharmaceutical dosage forms
(Friedr. Vieweg und Sohn Verlags GmbH, 2011)
The pK a values of cefdinir and cefixime, which are used in the treatment of bacterial infections, have been determined precisely in water and methanol-water binary mixtures (20% v/v) using spectrophotometric titration and ...
A novel RP-LC method for determination of pK a values of some anticancer agents and their assay
(2013)
A simple, reliable, and rapid RP-LC method has been developed for the determination of some anticancer drugs (daunorubicin, doxorubicin and vincristine sulfate) in their dosage forms and human urine. These compounds are ...
Solvent effects on pKa values of some substituted sulfonamides in acetonitrile-water binary mixtures by the UV-spectroscopy method
(2009)
The examination of the dissociation constants of sulfonamides is essential in drug-design studies and in explaining the biopharmaceutical properties of substances. The dissociation constants of ten common human and veterinary ...
Determination of dissociation constants of folinic acid (leucovorin), 5-fluorouracil, and irinotecan in hydro-organic media by a spectrophotometry method
(2010)
In this study, a multiwavelength spectrophotometry method was used for the determination of the dissociation constants of drugs used for treatment of colorectal cancer, folinic acid (leucovorin), 5-fluorouracil, and ...
Optimization of the experimental conditions for macrolide antibiotics in high performance liquid chromatography by using response surface methodology and determination of tylosin in milk samples
(2011)
The simple, rapid and sensitive liquid chromatographic separation of five macrolides (tilmicosin, erythromycin, tylosin, roxithromycin and josamycin) widely used in food producing animals was developed. Response surface ...
A validated RP-LC method for salmeterol and fluticasone in their binary mixtures and their stress degradation behavior under ICH-recommended stress conditions
(Maik Nauka Publishing / Springer SBM, 2014)
Simple, accurate, precise and fully validated analytical methods for the simultaneous determination of salmeterol xinafoate and fluticasone propionate in combined dosage forms have been developed. These drugs were exposed ...
Development and validation of a liquid chromatographic method for concurrent assay of weakly basic drug verapamil and amphoteric drug trandolapril in pharmaceutical formulations
(2012)
The analysis of weakly basic drugs such as verapamil by reverse-phase liquid chromatography remains a problem, particularly when present in combination with other drugs such as amphoteric compounds like trandolapril. In ...
