Urinary excretion studies of meldonium after multidose parenteral application
(Elsevier Science BV, Amsterdam, 2018)
Meldonium is a drug exhibiting cardioprotective and anti-ischemic effects. Due to its potential performance-enhancing benefit in sports, meldonium was added to the World Anti-Doping Agency list of prohibited substances in ...
Development of liquid chromatographic method for the analysis of dabigatran etexilate mesilate and its ten impurities supported by quality-by-design methodology
(Elsevier Science BV, Amsterdam, 2015)
In this paper, the development of reversed-phase liquid chromatographic method for the analysis of dabigatran etexilate mesilate and its ten impurities supported by quality by design (QbD) approach is presented. The defined ...
High-performance liquid chromatographic method for the determination of bumetanide in pharmaceutical preparations
(Journal of Pharmaceutical and Biomedical Analysis, 1989)
Application of Analytical Quality by Design concept for bilastine and its degradation impurities determination by hydrophilic interaction liquid chromatographic method
(Elsevier Science BV, Amsterdam, 2016)
This paper deals with the development of hydrophilic interaction liquid chromatographic (HILIC) method for the analysis of bilastine and its degradation impurities following Analytical Quality by Design approach. It is the ...
High performance thin layer chromatography (HPTLC) and high performance liquid chromatography (HPLC) for the qualitative and quantitative analysis of Calendula officinalis-Advantages and limitations
(Elsevier Science BV, Amsterdam, 2014)
Chromatography techniques such as HPTLC and HPLC are commonly used to produce a chemical fingerprint of a plant to allow identification and quantify the main constituents within the plant. The aims of this study were to ...
Spectrophotometric determination of obidoxime chloride as its Pd(II) complex in water and injections
(Journal of Pharmaceutical and Biomedical Analysis, 1987)
It has been established that obidoxime chloride reacts with palladium(II) chloride in the pH range 3.9-8.0 and forms a yellow water-soluble (1:1) complex with maximum absorbance at 355 nm. By applying the methods of Sommer, ...
Development and validation of reversed phase high performance liquid chromatographic method for determination of moxonidine in the presence of its impurities
(Elsevier Science BV, Amsterdam, 2012)
A simple, rapid, isocratic reversed-phase high-performance liquid chromatographic method was developed and validated for the analysis of moxonidine and its impurities in tablet formulations. The chromatographic separation ...
Electrochemical and theoretical study on interaction between erlotinib and DNA
(Elsevier B.V., 2023)
A comprehensive investigation of tyrosine kinase inhibitor erlotinib (ERL) electrochemical behavior and interaction with DNA was performed with the aim to clarify its redox mechanism and to determine the mode of binding. ...
Quality by Design approach in the development of hydrophilic interaction liquid chromatographic method for the analysis of iohexol and its impurities
(Elsevier Science BV, Amsterdam, 2015)
This study presents the development of hydrophilic interaction liquid chromatographic method for the analysis of iohexol, its endo-isomer and three impurities following Quality by Design (QbD) approach. The main objective ...
Use of palladium(II) chloride as colour-forming reagent in determination of pralidoxime chloride in water and tablets
(Journal of Pharmaceutical and Biomedical Analysis, 1988)
Pralidoxime chloride (PAM-2Cl) has been determined spectrophotometrically in Britton-Robinson buffer solution at pH = 6.45; the method is based on measurement of the absorbance of the Pd(II)-pralidoxime complex at 327 nm. ...
