title: Medication use by the elderly.
abstract: Medication use is correlated with the age-associated onset of chronic diseases for which drug therapy offers symptomatic relief, and assists in preventing the onset of disabling and life-threatening complications. However, high rates of medication use by older people raise a number of issues, ranging from concerns with rising expenditures for individuals and third-party insurers; increased risk of adverse drug reactions; toxic or interaction effects from concomitant use of multiple pharmaceutical agents, both physician and self-prescribed; and poor compliance with complex medication regimens by the more physically and mentally impaired. Although existing data do not support the theory of age as an independent predictor of drug-specific adverse reactions, older people have typically been excluded from clinical trials in the dynamic and changing field of pharmacotherapy. Furthermore, ingestion of a greater number of different agents clearly exposes individuals to higher risk of adverse reactions and interactions. Recent advances in information technology have facilitated multicenter clinical trials and post-marketing epidemiological surveillance studies of specific and concomitant medication use by individuals of all ages. The employment of such technology by insurers to determine appropriate prescribing or to control costs in the present limited state of knowledge is, however, premature. Furthermore, such techniques will not replace the need for careful clinical review of symptoms and total drug therapy by prescribing physicians, with modification of regimens and provision of appropriate information and instructions to older individuals and their caregivers.
