While patients with low back pain and osteoarthritis are often treated well using pure analgesics, patients with rheumatoid arthritis, and in particular those with ankylosing spondylitis, require the most potent anti-inflammatory drugs. Patients with cancer pain of moderate-to-severe intensity also benefit from them, but this is limited by the progression of the disease and the ceiling effect of non-steroidal anti-inflammatory drugs (NSAIDs). Regular endoscopic investigation of the upper gastro-intestinal tract should be considered for the prevention of fatal side-effects in patients at risk.

Increases in functional activity, return to work and closure of disability claims should also be considered.
