A container that includes a canister sealed with a metering valve, having a metering chamber is described. The metering valve includes one or more sealing gaskets substantially constructed from a polymer of EPDM and the metering chamber surface presents a substantially fluorinated surface to a pharmaceutical aerosol formulation within the container. Metered dose inhalers that include the container are also described, as are packages that include the metered dose inhalers.
