Abstract
Rheumatoid arthritis (RA) in the elderly may be mild or severe, with features that are similar to those seen in younger patients. As such, the treatment regimen in the elderly is almost the same as in younger patients. Methotrexate is the most popular disease-modifying antirheumatic drug (DMARD) for the treatment of RA in the US and Europe. It has excellent efficacy and an acceptable toxicity profile. However, a number of patients do not tolerate methotrexate and an alternative DMARD should be chosen.
In the elderly, choice of an alternative DMARD should be made after careful consideration of several age-related factors including concomitant diseases, existing medication, drug compliance, and altered age-related physiology and pharmacokinetics.
In elderly patients with RA who are unable to tolerate methotrexate, the alternatives are hydroxychloroquine or sulfasalazine for mild-to-moderate disease and cyclosporin or leflunomide for severe disease, given in combination with low-dose oral corticosteroids. This is primarily due to their efficacy combined with a relatively low toxicity profile compared with other DMARDs, such as gold compounds, penicillamine, azathioprine and alkylating agents. Where the above DMARDs are contraindicated, anticytokine therapy should be considered.
The therapy of RA is a dynamic process and requires a delicate balance of benefits and risks. Experience and familiarity with the currently available agents, and knowledge of the nature of the disease are necessary in order to make better therapeutic decisions.
