Presspart Manufacturing, a specialist in the field of bespoke metal and plastic drug delivery components and devices, has released a new white paper entitled ‘Modifying MDI Canister Surfaces to Improve Drug 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 a MDI canister.

This approach has a number of advantages to alternative coatings but requires careful optimisation to ensure the highest quality finish and MDI performance.
