[NON-ONCOLOGIC CHRONIC PAIN TREATMENT WITH OPIATES].

Non-oncologic chronic pain is a very common symptom. It causes great impact on daily activities of people who suffer it. The incidence of this type of pain is rising due to the increase in life expectancy. The most affected population is geriatric population. Back pain, osteoarthritic pain and neuropathic pain are the most prevalent types of non-oncologic chronic pain. Opiates, among other analgesic drugs, are used to alleviate this type of pain. Opiates are divided into minor opiates (tramadol, codeine) and major opiates (morphine, fentanyl, oxycodone, methadone). Opiates are very effective to treat pain, but they also have important adverse effects that we must know and try to prevent. One of these adverse effects is the opiates ability to cause dependence, tolerance, addiction and other aberrant behaviors. Terminology of these concepts is sometimes confusing. It is necessary to be careful and control the patient periodically in order to avoid these aberrant behaviors. However, if health professionals take precautions to prevent these behaviors, the risk is considerably reduced. Controlling patients on opiate treatment is essential to achieve a correct use if these drugs.
