ABSTRACT:
A dual seal configuration for an aerosol canister containing a medicinal aerosol formulation. The canister includes a vial body and valve ferrule sealed by first and second sealing members to form a chamber that contains the medicinal aerosol formulation. The dual seal configuration reduces leakage of contents, and is particularly helpful where the formulation includes hydrofluorocarbon propellant and an ethanol cosolvent. The first seal can be selected to be a barrier to the formulation components, while the second seal can be relatively more labile to such components.
