Validation of a high-performance liquid chromatography method for the determination of pancuronium in Pavulon injections
(Elsevier Science BV, Amsterdam, 2002)
A new high-performance liquid chromatography (HPLC) method was developed for the quality control of pancuronium bromide and its degradation products. The HPLC method used a 5-mum Supelcogel ODP-50 (150X4 cm) column with ...
Experimental design in reversed-phase high-performance liquid chromatographic analysis of imatinib mesylate and its impurity
(Elsevier Science BV, Amsterdam, 2004)
For the determination of the optimal RP-HPLC chromatographic conditions for the separation of imatinib mesylate and its impurity STI 509-00 experimental design 2(4) was applied. All the factors that affect imatinib ...
Investigation of chromatographic conditions for the separation of ofloxacin and its degradation products
(Elsevier Science BV, Amsterdam, 2006)
A sensitive, precise, and accurate reversed-phase high-performance liquid chromatography (RP-HPLC) method was developed and validated for simultaneous determination of fluoroquinolone antibacterial ofloxacin and its ...
Validation of a high-performance liquid chromatographic method for the simultaneous determination of tramadol and its impurities in oral drops as a pharmaceutical formulation
(Elsevier Science BV, Amsterdam, 2006)
The novel, rapid high performance liquid chromatographic method for the determination of tramadol hydrochloride and its three impurities was developed and validated. The method can simultaneously assay potassium sorbate, ...
Validation of liquid chromatographic method for analysis of lidocaine hydrochloride, dexamethasone acetate, calcium dobesilate, buthylhydroxyanisol and degradation product hydroquinone in suppositories and ointment
(Elsevier Science BV, Amsterdam, 2005)
In this paper, there was developed a sensitive, precise and accurate reversed-phase liquid chromatographic (RP-HPLC) method and validated for simultaneous determination of lidocaine hydrochloride, dexamethasone acetate ...
Chemometrical evaluation of ropinirole and its impurity's chromatographic behavior
(Elsevier Science BV, Amsterdam, 2009)
The aim of this study was the chemometrical evaluation of ropinirole and its impurity's (4-[2(dipropylamino)ethyl]-1H-indol-2,3-dione) chromatographic behavior in systematic and the most efficient way. For that purpose, ...
Development of liquid chromatographic method for fosinoprilat determination in human plasma using microemulsion as eluent
(Elsevier Science BV, Amsterdam, 2005)
Fosinopril sodium presents a prodrug for the active angiotensin converting enzyme (ACE) inhibitor, fosinoprilat. The dual elimination of fosinoprilat by the liver and the kidney distinguishes fosinopril from other angiotensin ...
Monitoring of fosinopril sodium impurities by liquid chromatography-mass spectrometry including the neural networks in method evaluation
(Elsevier Science BV, Amsterdam, 2008)
In this paper, the mass spectrometry (MS) detection has been applied for screening of fosinopril sodium impurities which arise during forced stress study. Before MS analysis, liquid chromatographic method with suitable ...
Ultra-thin-layer chromatography mass spectrometry and thin-layer chromatography mass spectrometry of single peptides of angiotensin-converting enzyme inhibitors
(Elsevier Science BV, Amsterdam, 2011)
The separation of structurally related angiotensin-converting enzyme (ACE) inhibitors lisinopril, cilazapril, ramipril and quinapril and their corresponding active diacid forms (prilates) by conventional TLC silica gel 60 ...
Correlation between ultra-high performance liquid chromatography-tandem mass spectrometry and reversed-phase thin-layer chromatography hydrophobicity data for evaluation of angiotensin-converting enzyme inhibitors absorption
(Elsevier Science BV, Amsterdam, 2012)
In this research seven ACE inhibitors (enalapril, quinapril, fosinopril, lisinopril, cilazapril, ramipril, benazepril) were studied to evaluate the correlation between their absorption and ultra-high performance liquid ...
