[Opioids in "non-malignant" pain-results of long-term treatment in patients with rheumatic disease.].
The oral administration of strong opioids like morphine is a very effective treatment in cancer pain. However, these analgesics are rarely prescribed for patients suffering from severe "non-malignant" pain. We examined the effects of oral opioids (morphine sulphate tablets, buprenorphine and levomethadone) given to patients with intractable rheumatic pain, which were refractory to other therapeutic measures. The origin of pain was inflammation or a degenerative lesion of the spine. Within a period of more than 3 years, 12 patients were treated accordingly. In 9 patients we could achieve sufficient pain relief, two of them showing improvement only after having changed the initially prescribed drug. We had to stop opioid medication in two patients because of side-effects and, moreover, in one patient because of failure to produce analgesia. 775 weeks of treatment were documented until December 31th, 1990, with an individual duration ranging from 11 to 145 weeks. It was necessary to increase the dose of morphine in the course of treatment of one patient, who is up to now being treated for more than 77 weeks. In all other patients the doses were either stable or varied. No severe side-effects such as respiratory depression were associated with long-term opioid therapy. Constipation was observed in 4 patients, nausea in two patients and urinary retention in one patient. These side-effects could be well treated by an additional medication. No drug abuse, dependence or tolerance were observed. Strong opioids are not analgesics of first choice in patients with rheumatic disease, but an opioid medication should be considered-as well as in patients with intractable pain caused by another disease-when alternative therapeutic measures have failed. The principles of opioid medication in rheumatic pain are similar to those in patients with cancer pain.
