this is the gist: "There is a new drug that acts similarly to ibuprofen, but appears to be less aggressive towards kidneys. Equally as bad for the heart."
However 70% of the participants failed to complete the study, so its not long term. No percentage risks are quoted. It also doesn't compare how effective celecoxib is compared to the much cheaper and well understood(interaction wise) ibuprofen.
It also notes that high doses were not tested: "600mg ibuprofen three times a day"
That my friend is a fucking large dose, as in three weeks and you have an ulcer dose.
