Outcomes research: clinical trials in the elderly

Abstract

Very few clinical trials have been done in the elderly. This report reviews results of two completed studies and describes one in progress. The largest published study was a United States Veterans Affairs Administration study in newly diagnosed patients with epilepsy. It compared carbamazepine to gabapentin and lamotrigine, and found that, although equivalent in efficacy, the newer antiepileptic drugs (AEDs) were better tolerated. This study also highlighted many of the difficulties in recruiting and retaining elderly patients in studies, the large number of comorbidities, and the problems of distinguishing seizures in the elderly from other symptoms. Another study of new-onset epilepsy suggested that a large percentage of elderly patients respond to initial AED therapy, but side effect profiles differ. More studies are needed to better define the risk/benefit relationships in elderly patients.
