Abstract Dissolution of bicalutamide processed with polyvinylpyrrolidone by either supercritical carbon dioxide or ball milling has been investigated. Various compositions as well as process parameters were used to obtain binary systems of the drug with the carrier. Thermal analysis and powder X-ray diffractometry confirmed amorphization of bicalutamide mechanically activated by ball milling and the decrease in crystallinity of the supercritical carbon dioxide-treated drug. Both methods led to...

Abstract The aim of this research was to develop immediate release tablets comprising solid dispersion (IRSDTs) of tadalafil (Td) in a vinylpyrrolidone and vinyl acetate block copolymer (PVP-VA), characterized by improved dissolution profiles. The solid dispersion of Td in PVP-VA (Td/PVP-VA) in a weight ratio of 1:1 (w/w) was prepared using two different processes i.e. spray drying and ball milling. While the former process has been well established in the formulation of IRSDTs the latter has...

Abstract The objective of present study was to explore the application of Soluplus® as a stabilizer for the preparation of febuxostat (FEB) nanocrystals using ball milling technique. Preliminary trials were performed for the selection of stabilizer from HPMC VLV, PVA, PVP K30, Poloxamer 188 and Soluplus®. Soluplus® stabilized FEB nanocrystals were found stable and had least particle size as compared to the batches prepared using other stabilizers. A systematic optimization of critical...

Background: The objective of the present study was to investigate the combinative effect of ball milling and solvent displacement method on size reduction of Celecoxib particles. Celecoxib is a poorly water soluble cyclooxygenase 2 inhibitor which has a wide range of therapeutic applicability. Methods: Microparticles were developed via solvent displacement method followed by planetary ball milling. In order to obtain an optimized size and size distribution of Celecoxib microparticles various...

Chitosan has great potential as a pharmaceutical excipient. In this study, chitosan flake was micronized using cryo-ball and cryo-jet milling and subsequently sterilized with nitrogen plasma. Micronized chitosan was characterized by laser diffraction, scanning electron microscopy (SEM), conductometric titration, viscometry, loss on drying, FTIR, and limulus amebocyte lysate (LAL) assays. Cryo-jet milling produced mean particle size of 16.05 μm, 44% smaller than cryo-ball milling. Cryomilled...
