FDA approves Celebrex for ankylosing spondylitis

Along with the news that Celebrex's label will come with new warnings about its cardiovascular and gastrointestinal risks comes word that the FDA has approved it for anyklosing spondylitis (press release, Reuters). Considering that many of us have been prescribed it for AS anyway -- many drugs are prescribed as treatments for which they are not approved -- I have no idea how significant this announcement is.
