Prostaglandins establish the inflammatory response.
This mechanism may relate to the variation in response between patients. Scientific studies have shown a correlation between concentration of the drug and effect, but do not explain the differences in individual patient responses. This interaction can enhance either therapeutic or toxic effects of either drug. A trial period of three weeks should be given for anti-inflammatory effectiveness to be observed. Naproxen, indomethacin, and diclofenac were viewed as an intermediate risk.
