Company's plasma coating technology and face seal valve both help pMDI systems improve product performance. Plasma coating technology helps ensure technical success with inhalation components for challenging hydrofluoroalkane (HFA) formulations by creating a layer that protects against degradation, deposition and corrosion. The ultra thin coating is suitable for both plastics and metals. The face seal valve eliminates the need to prime an inhaler by collecting the dose as the inhaler is fired. Traditional pMDI valves operate on a “dose retention” principle, collecting the dose when the valve stem is released after firing. This can lead to loss of prime or loss of dose, which is why patients are advised to prime these inhalers by firing an uninhaled shot before use. The face seal valve eliminates this extra step. The technology helps ensure patients receive a full dose of medication with every use, including single shot products. Both plasma coating technology and the face seal valve are available as parts of a complete system program, or as stand alone components.
