A mix of biocompatible macromolecules (poly(vinyl alcohol) (PVA) and poly(vinyl pyrrolidone) (PVP)) has been shown previously to enhance the physical stability of non-aqueous pharmaceutical suspensions. The aim of this work was to assess the feasibility of employing such a combination to facilitate the formulation of deoxyribonuclease I (DNase I) in a metered dose inhaler (MDI) using hydrofluor...

Cannabidiol (CBD) and cannabigerol (CBG) are two active pharmaceutical ingredients, derived from cannabis plant. In the present study, CBD CBG were formulated with polyvinyl(pyrrolidone) (PVP) Eudragit L-100, using electrohydrodynamic atomization (electrospinning). The produced fibers smooth uniform in shape, average fiber diameters range of 700–900 nm for PVP 1–5 μm L-100 fibers. encapsulation...

Abstract Diverse wet adhesives were prepared from oleic acid (OA), polyvinyl pyrrolidone (PVP), and cis -1,4-polyisoprene (PI) at different ratios for attracting trapping insects. The of (PVP-PI)/OA 1:2, 1:1 2:1 (g/g). ratio between PVP PI was 9 to 1 blends irradiated with doses 10 50 kGy. Adhesion properties, water sorption, Fourier transform infrared spectroscopy, thermogravimetric analysis s...

Two polymer solutions of polyacrylonitrile, polyvinyl pyrrolidone, and Ni(CH3COOH)2 in dimethylformamide were electrospun into ternary composite nanofibers, followed by stabilization and carbonization processes to obtain porous carbon/nickel composite nanofibers with diameters of 100-200 nm. The study revealed that carbon/nickel composite nanofibers were successfully prepared, which allowed nic...

The purpose of this study is to investigate the effects of N-methyl-2-pyrrolidone on the thermosensitive properties of aqueous ethylene oxide-propylene oxide block copolymer (Lutrol(®) F127) system. Due to the aqueous solubility enhancement and biocompatibility, N-methyl-2-pyrrolidone is an interesting solubilizer for the poorly water soluble drugs to be incorporated in the Lutrol(®) F127 syste...
