Ensuring appropriate and cost-effective drug use will be an important component of the agenda for future research on successful aging. Because they increase survival and improve quality of life, medications are among the most widely used and highly valued interventions for diseases of older adults. At least 85% of senior citizens use one prescription medication, and most use more than one (1). In 2002, more than 3 billion prescriptions were filled in the United States at a total cost of $183 billion, an increase of 11% from 2001 (2). Millions of older adults also use nonprescription medications and herbal therapies, which can increase the risk for adverse drug interactions and events. The use and costs of medications will probably continue to increase, driven by growing numbers of older adults with chronic diseases amenable to pharmacotherapy (3).
