Abstract
New ecological, sustainability and practicality analytical methodologies became constant in the modern pharmaceutical analysis. Likewise, a simple, rapid, stability-indicating high-performance liquid chromatography (HPLC) method was developed and validated for simultaneous determination of lamivudine (3TC), zidovudine (ZDV) and nevirapine (NVP) in pharmaceutical formulations. The HPLC method was carried out on a monolithic C18 column (100 mm × 4.6 mm i.d.), maintained at 30°C. The mobile-phase consisted of ammonium acetate (pH 4.5; 10 mM)-methanol-acetonitrile (65:28:7, v/v/v), run at a flow rate of 2.0 mL/min, using photodiode array (PDA) detection at 270 nm. Validation parameters such as the specificity, linearity, precision, accuracy and robustness were evaluated according to the International Council for Harmonisation (ICH) guidelines. From the results obtained, the developed HPLC method was successfully applied for the simultaneous quantitative analysis of 3TC, ZDV and NVP in tablet dosage forms. The chromatographic separation was obtained in less than 3 min and it was suitable for high-throughput analysis. In addition, the greenness assessment, the holistic overall evaluation and the practicality check using the novel Analytical GREEnness Metric Approach and Software (AGREE) calculator, the RGB-12 model and Blue Applicability Grade Index (BAGI), respectively, were performed. The results demonstrated the environmental friendliness (AGREE), practicality (BAGI) and holistic sustainability profile (RGB-12 model) of the proposed method.
期刊介绍：
The Journal of Chromatographic Science is devoted to the dissemination of information concerning all methods of chromatographic analysis. The standard manuscript is a description of recent original research that covers any or all phases of a specific separation problem, principle, or method. Manuscripts which have a high degree of novelty and fundamental significance to the field of separation science are particularly encouraged. It is expected the authors will clearly state in the Introduction how their method compares in some markedly new and improved way to previous published related methods. Analytical performance characteristics of new methods including sensitivity, tested limits of detection or quantification, accuracy, precision, and specificity should be provided. Manuscripts which describe a straightforward extension of a known analytical method or an application to a previously analyzed and/or uncomplicated sample matrix will not normally be reviewed favorably. Manuscripts in which mass spectrometry is the dominant analytical method and chromatography is of marked secondary importance may be declined.
