[Pharmacological treatment of osteoarthritis in the elderly]

Osteoarthritis (OA) is the most common cause of functional disability in the elderly. Pain and loss of motion induce a vicious circle, leading to instability, frailty and ultimately invalidity. Currently, there is no treatment to reverse or slow the disease progression to a clinically meaningful extent. Thus, the primary goal of OA treatment in the elderly is pain relief and preservation of joint function. For this, pharmacological, non-pharmacological and if necessary surgical treatment regimes must form an integrated concept. However, the real challenge is polymorbidity and other age-related or age-associated factors, which influence the course of disease and its therapy unfavorably. The changes in pharmacokinetics and -dynamics in the elderly can be compensated for the nonopioid and opioid-analgesics by the well known "start low, go slow" approach. More problematic are non-steroidal anti-inflammatory drugs (NSAIDs), which are most often used for symptomatic treatment of OA: Patients over 65 have an enhanced susceptibility to the gastrointestinal and renal side effects of NSAIDs; all NSAIDs, not only coxibs, increase the cardiovascular risk in patients with such a disease; number and severity of drug interactions is elevated due to age-associated polypharmacy. Thus, NSAIDs, including coxibs, should be used with great caution for treatment of OA in the elderly.
