Abstract
Unfractionated heparin is an anti-inflammatory mucoactive agent, with the potential to treat the inflamed and mucus-obstructed airways in patients with cystic fibrosis. In this study, unfractionated heparin has been spray-dried to produce spherical micronized particles in the size range 1-5 microm, which is suitable for delivery by dry-powder inhalation. Spray drying parameters have been optimized using a 2(4) factorial experimental design. The feed concentration and atomization spray flow rate have the greatest effects on recovery (typically 60%) and particle size.
