Embracing Spray Drying Strategies

Orally inhaled drug products have several therapeutic advantages over other dosage forms − most notably, a more direct delivery to the central nervous system. By their very nature, they avoid the first pass effect through the liver, for both regional as well as systemic delivery. This allows drug developers to formulate delivery strategies that reduce the dosage strength and limit the risk of adverse side effects. While pharmaceutical companies have long recognised the potential of inhalation products, many are starting to explore development techniques such as spray drying in more depth.

This article will outline the benefits of using respirable-engineered dry powder for inhalation products, as well as discussing how the new 505 (b) (2) application route for faster approval of new formulations that use existing APIs is a suitable pathway to getting these products to market quickly and efficiently.

Modifying MDI Canister Surfaces to Improve Drug Stability & Drug Delivery

Presspart Manufacturing Ltd

Hydrofluoroalkane (HFA)-based propellants are widely used in modern metered-dose inhalers (MDIs), due to their lack hazardous and environmentally-damaging effects. However, an HFA's active pharmaceutical ingredient can interact with the canister substrate, causing deposition of the drug to the canister walls, or interact with the solution, causing degradation and resulting in increased impurity levels. 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. Richard Turner, Business Development Director, Presspart Manufacturing Ltd, explains.
