title: [Opioid use in osteoarthritis: From guidelines to clinical care].
abstract: Three treatment guidelines for the treatment of knee and hip osteoarthritis (OA) which pick up the aspects of treatment supported by evidence have been published. Opioid drugs have an important role in symptomatic treatment. The guidelines, the effectiveness, and the safety of opioid analgesics in osteoarthritis, as well as its implications in clinical practice are reviewed. Tramadol is the opioid with the biggest evidence of effectiveness and safety, besides being the most used in clinical practice. Strong opioids (transdermic brupenorphine or fentanyl, oxycodone, and morphine) can be used in severe pain that does not respond to other treatments. Opioids can be used in patients that have moderate or severe pain or in those with inadequate response or intolerance to NSAID's. The opioids also have a sedative effect that facilitates sleep and can improve functional limitations and anxiety. The side effects are frequent; they usually appear at the beginning of treatment and are rarely severe, but frequently force to stop treatment.
