AbstractDespite its high prevalence, chronic pain is suboptimally treated in approximately one half of affected patients. Failure to recognise and manage comorbid physical and psychosocial impairments may contribute to the perpetuation of chronic pain. Knowledge of the potential advantages and disadvantages of available analgesic medications will permit informed selection of the appropriate medication for the individual chronic pain patient. Ultimate therapeutic goals will also influence analgesic medication selection. For the patient with chronic pain requiring analgesic treatment for an extended period of time, long-acting analgesics are recommended. Theoretically, these agents will provide sustained analgesia by minimising the end-of-dose pain that is often seen with short-acting medications, with improved patient convenience and a potential for reduced risk of adverse events. The extended-release formulation of tramadol (tramadol ER) has proven efficacy in chronic pain conditions such as osteoarthritis and low back pain, as well as a favourable tolerability profile. In addition, tramadol ER has been shown in clinical trials to improve pain-related sleep disturbances and physical function in patients with chronic pain from osteoarthritis and low back pain.
