The major constituents of the neuropathic pain market are lower back pain, neuralgia/fibromyalgia, diabetic neuropathic pain and pain associated with multiple sclerosis. The nociceptive pain market is driven by the prevalence of the major indications of arthritic pain, particularly osteoarthritis and rheumatoid arthritis, post-operative pain, cancer-related pain and HIV-related pain.
