Generic Proair HFA
At this time, no generic versions of Proair HFA are available. It is unclear why this is so, as the first patents for the drug have expired. It is possible that some of the drug's other, unexpired patents are providing protection against generic competition.
Generic Proair HFA: An OverviewProair HFA® (albuterol inhaler) is a prescription medication used to treat asthma and other similar lung problems. It is part of a class of asthma drugs known as beta-adrenergic receptor agonists, or beta agonists for short.
Proair HFA is manufactured by Teva Respiratory, LLC. It is currently under the protection of a patent that prevents any generic Proair HFA from being manufactured in the United States. Proair HFA is one of only a few environmentally friendly albuterol inhalers. Older, "traditional" albuterol inhalers will no longer be available after December 31, 2008. None of the new inhalers have generic equivalents at this time.
When Will Generic Proair HFA Be Available?
The first patents for Proair HFA expired in November 2009 and July 2010. It is unclear why generic versions of Proair HFA are not yet available. Perhaps the other listed patents (the next of which is set to expire in February 2014) provide protection against generic competition.
When multiple patents are listed (as is the case with Proair HFA), it is often unclear which patents provide true protection against generic competition. Therefore, it is difficult (if not impossible) to predict when exactly a generic version of Proair HFA will become available.
