[Therapy of pain in multiborbid elderly patients].
All human organ systems are prone to age-related physiological changes. Functional impairment is especially found in the liver, the kidneys, the nervous system, the gastrointestinal tract and the blood vessels. Changes in metabolism cause, e.g., changes in the composition of blood, reduction in neurotransmitters and the respective receptors, changes in calcium homeostasis with consequences for the stability of bones. As with any pharmacotherapy, the treatment of pain must consider these age-related factors. Adequate pain treatment is especially important in elderly patients, because the number of morbidities increases together with the number of pain conditions of different origin. In Germany, most patients with severe pain are undertreated. Although tumor pain, e.g., can be relieved in up to 95% of patients, up to 40% of patients under medical treatment still have pain, the German Pain League states. The WHO's pain ladder, developed in the 1980ies, is still regarded as an appropriate guideline, albeit too often disregarded by physicians, reflecting the reserve of patients and doctors towards opioids. With progress in opioid therapy, however, experts tend to early prescription of step-III-analgesics without sticking to the steps of the WHO ladder. Constipation, the major side effect of opioids, can be overcome by co-medication with laxatives. The combination of slow-release oxycodone with naloxone, an orally given antagonist of intestinal micro-receptors is effective as analgesic and maintains the normal bowel function.
