Colistin, a cyclic polypeptide linked to a fatty acyl tail, is an old antibiotic with potential toxicity when administered intravenously; however, for treating lung infections, dry powder inhalers (DPIs) have potential to deliver high doses directly to the site of infection. This study has examined the potential to engineer microparticles of colistin, with optimised surface energy, to create particles for effective use in DPIs. Methods: Spray dried colistin sulphate powders were obtained using a Buchi Mini-Spray Drier 190. Inverse Gas Chromatography (IGC) was used to determine the surface energies of the different particles. In vitro dispersion efficiency was measured by aerosolising into a twin stage impinger.
