silica coated magnetite nanoparticles were covalent grafted with 3-aminopropyl trimethoxysilane to give aptscmnps. reaction of the resulted nanomaterial with 4-formyl benzo-12-crown-4 ether afforded fb12c4/aptsmnps nanocomposite material in which the crown ether moiety was attached through propyl chain spacer. characterization of the prepared nanocomposite was performed wit...
A biosimilar is a biological medicinal product that contains a version of the active substance of an already authorized original biological medicinal product. Biosimilarity to the reference product (RP) in terms of quality characteristics, such as physicochemical and biological properties, safety, and efficacy, based on a comprehensive comparability exercise needs to be established. SB2 (Flixab...
Both the active pharmaceutical ingredient and the vehicle physicochemical characteristics are retained to be the main features responsible for favorable topical bioavailability. Emulsion systems based on natural-origin alkyl polyglucoside (APG) emulsifier (cetearyl glucoside & cetearyl alcohol) present promising vehicles in contemporary pharmaceutical compounding [1], but require further charac...

the present study was undertaken to develop a suitable transdermal matrix patch of ketorolac tromethamine with different proportions of polyvinyl pyrrolidone (pvp) and ethyl cellulose (ec) using a d-optimal mixture design. the prepared transdermal patches were subjected to different physicochemical evaluation. the surface topography of the patches was examined by scanning electron microscopy (s...
The origin of the concept of a molecular complex between oxygen and hemoglobin can be traced to Stokes, a century and a half ago. Subsequently, physicochemical concepts of equilibria provided a path to quantitative formulations of these ligand-receptor interactions. Then, it took a quarter of a century before a proper format was prepared in terms of four stoichiometric equilibria and their asso...
