When Will Generic Xopenex HFA Be Available?
The first patent for Xopenex HFA currently expires in November 2009. This is the earliest date that a generic version of Xopenex HFA could become available. However, there are other circumstances that could arise to extend the exclusivity period of Xopenex HFA beyond 2009. This could include such things as other patents for specific Xopenex HFA uses or lawsuits. Once Xopenex HFA goes off patent, there may be several companies that will begin manufacturing a generic Xopenex HFA drug.
