This group of NSAIDs has the advantage of having fewer gastrointestinal side effects – less abdominal discomfort and less risk of gastrointestinal bleeding, than conventional NSAIDs. There are three different COX-2 inhibitors currently available to the public– Vioxx,
Celebrex and Bextra. COX-2 inhibitors have been associated with some liver dysfunction, although not as commonly as other NSAIDs. Recently, Vioxx has been removed from the market due to heart-related problems.
