Modifying MDI Canister Surfaces to Improve Stability and Drug Delivery

Over the past few years, a number of surface coatings have been developed that can be applied to MDI canisters and valve components, to protect the contents from deposition and degradation. More recently, plasma processes have been developed to modify and improve the surface energy performance of an MDI canister. As Richard Turner of Presspart Manufacturing explains, this approach has a number of advantages over alternative coatings, but requires careful optimisation to ensure the highest quality finish and MDI performance.…pdf.pdf
