[ 1 ] - GC-FID and HPLC-DAD Methods for the Determination of Menadione Sodium Bisulphite Directly and by Converting Menadione Sodium Bisulphite to Menadione in Pharmaceutical Preparation

GC-FID and HPLC-DAD were developed for determination of menadione (MN) and menadione sodium bisulphite (MSB). By means of each method, quantitative analysis of MSB in commercial pharmaceutical was performed in both direct analysis of MSB and analysis of MN by converting MSB to MN with sodium carbonate. GC-FID method was carried out on the HP-5 capillary column using nitrogen gas. HPLC-DAD metho...

[ 3 ] - Metabolomic profiling of liver tissues of rat after acute administration of Vardenafil

Erectile dysfunction (ED) diseases have almost affected 100 million men all over the world. Orally administered phosphodiesterase 5 (PDE 5) inhibitors are the most used pharmaceutical formulations for the treatment of ED. In this study, it is aimed to investigate the metabolomics feature of orally administered vardenafil in rats. To carry out the experimental procedure eight male Wistar albino ...
