of the propionic acid class (which puts it in the same class as ibuprofen) and is commonly used for relief of a wide variety

of pain, fever, swelling and stiffness.:665,673 It is the preferred NSAID for long-term use in people with a high risk of

cardiovascular (for example, heart attacks or strokes)complications, due to its relatively low risk of causing such complications.

which is high risk. In order to reduce the risk of stomach ulceration, it is often combined with a proton-pump inhibitor 

(a medication that reduces the production of stomach acid) during long-term treatment, in those with pre-existing stomach ulcers,

or a history of developing stomach ulcers while on NSAIDs.
