Determination of carvedilol and its impurities in pharmaceuticals
(Vieweg, Wiesbaden, 2005)
A reversed-phase high-performance liquid chromatographic (RP-HPLC) method has been developed for separation of carvedilol and its impurities from Karvileks tablets. The best separation was achieved on a 100 mm x 4.6 mm, 5 ...
Simultaneous determination of bifonazole and benzyl alcohol in pharmaceutical formulations by reverse-phase HPLC
(Springer Heidelberg, Heidelberg, 2005)
A simple, precise and sensitive reverse-phase high performance liquid chromatographic (RP-HPLC) method has been developed for the quantitation of bifonazole, an imidazole antifungal, simultaneously with benzyl alcohol, ...
Chemometrical approach in fosinopril-sodium and its degradation product fosinoprilat analysis
(Springer Heidelberg, Heidelberg, 2004)
In this paper the experimental design has been applied to define the optimum chromatographic conditions for the separation of Fosinopril sodium and its degradation product, fosinoprilat. Fosinopril is a prodrug and after ...
Stability testing of cefuroxime in tablets by micellar liquid chromatography
(Springer Heidelberg, Heidelberg, 2004)
Cefuroxime is a broad-spectrum second-generation bactericidal cephalosporin antibiotic active against beta-lactamose-producing strains. Anti-cefuroxime, the geometric isomer of cefuroxime, might be present in cefuroxime ...
Chromatographic behavior of fosinopril sodium and fosinoprilat using neural networks
(Springer Heidelberg, Heidelberg, 2008)
In this paper, the chromatographic characterization of fosinopril sodium and fosinoprilat is presented. The first stept was pK(a) determination for the active substance and its degradation product using RP-LC. It was ...
HPLC determination of lorazepam and lorazepam-related compounds in pharmaceutical formulations
(Vieweg, Wiesbaden, 2000)
A sensitive, accurate and reproducible high performance liquid chromatographic (HPLC) procedure has been developed for the separation and analysis of lorazepam and related compounds. A 20-muL sample was separated by ...
Salting-out thin-layer chromatography of some angiotensin converting enzyme inhibitors on different sorbents
(Vieweg, Wiesbaden, 2001)
Chromatographic behaviour of six anti hypertensive drugs from the class of ACE inhibitors was studied under conditions of salting-out thin-layer chromatography on silica-gel, cellulose and polyacrylonitrile (PANS) as ...
UV-densitometric determination of maprotiline, desipramine and moclobemide in pharmaceutical dosage forms
(Vieweg, Wiesbaden, 2003)
Maprotiline, desipramine and moclobemide are widely used in the treatment of depression. The content of these antidepressants in bulk drug and pharmaceutical formulations were determined by TLC and in situ densitometry ...
