Making fine particles of inhalable drugs

By Chemical Engineering |

A team from the School of Chemical Sciences and Engineering, at the University of New South Wales (Sydney, Australia; www.unsw.edu.au), has developed a process for the micronization of insulin called Arise (Atomized Rapid Injection for Solvent Extraction). According to BioParticle Technologies Pty. Ltd. (BPT; Sydney; www.bioparticletechnologies.com), the company marketing Arise, the technology offers several advantages over other existing supercritical fluid technologies. The team leader, professor Neil Foster who invented the Arise process, says “this technology allows us to shrink the particle size of existing drugs and make them better suited for pulmonary delivery.” Arise is a supercritical fluid (SCF) precipitation process employing the energized rapid release of organic solutions and the anti-solvent capability of supercritical CO2 for the precipitation of pharmaceutical compounds from organic solvents. It exploits a pressure differential and rapid injection to atomize organic solutions into a vessel containing supercritical CO2 without using capillary nozzles. This results in a more homogeneous distribution of organic solution for precipitation to occur within the entire vessel containing the supercritical CO2. The…
