Quantitative analysis of analgoantipyretics in dosage form using planar chromatography
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
In the therapy of pain of weaker genesis, frequently used drugs usually represent a mix of analgoantipyretics of different chemical structures, mostly derivatives of salicylic acid, pyrazolone and p-aminophenol as well as ...
The use of a response surface methodology on HPLC analysis of methyldopa, amiloride and hydrochlorothiazide in tablets
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
A multifactor optimisation technique is successfully applied to develop a new HPLC method in which methyldopa, hydrochlorothiazide and amiloride were analysed and determined on a C18 column with detection at 286 nm. The ...
A preliminary study of beta-cyclodextrin/metoprolol tartrate inclusion complex for potential enantiomeric separation
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
The inclusion complex formation between Metoprolol tartarata (MeT) and beta -cyclodextrin (beta -CD) has been investigated using hyperchromic shift at lambda (max) 274.4 nm of MeT. Different parameters such as stirring ...
Simultaneous HPLC determination of nitrendipine and impurities of the process of synthesis
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
A method has been developed for separation of nitrendipine and its impurities of reaction partners and side reaction products by high-performance liquid chromatographic method on a RP-ls column and detection at 238 nm. The ...
Analytical method development supported by DoE-DS approach for enantioseparation of (S,S)- and (R,R)-moxifloxacin
(Elsevier B.V., 2023)
In this paper, method for enantiomeric purity testing of fourth-generation fluoroquinolone, moxifloxacin hydrochloride, was developed and validated. Exceptional enantioselectivity for this assay was achieved using cyclodextrin ...
Predicting liquid chromatography−electrospray ionization/mass spectrometry signal from the structure of model compounds and experimental factors; case study of aripiprazole and its impurities
(Elsevier Inc., 2023)
A priori estimation of analyte response is crucial for the efficient development of liquid chromatography–electrospray ionization/mass spectrometry (LC–ESI/MS) methods, but remains a demanding task given the lack of knowledge ...
Coulometric determination of sulphisomidine, sulphamethoxydiazine and sulphamoxole
(Journal of Pharmaceutical and Biomedical Analysis, 1991)
Determination of anti-secalin antibodies in sera from coeliac patients by ELISA-based assay
(Elsevier, 1998)
Coeliac disease (CD) is a permanent intolerance
to dietary prolamins (alcohol soluble protein fraction of cereal gluten) from selected cereals (wheat,
rye, barley and oats) resulting in small intestinal
villus atrophy ...
