Assessing Medicines for Use in the Geriatric Population.

Abstract

The aging processes alter the body's response to a medicine's pharmacokinetics, pharmacodynamics, and susceptibility to adverse effects. In addition, older adults, especially the oldest age category (85+ years) or those with multiple chronic health conditions, polypharmacy, or frailty, are under-represented in clinical trials of new medicines. Evidence-based prescribing guidelines based on these trials might result in inappropriate prescription, increasing the risk of drug interactions and adverse drug reactions. Regulators face a conundrum between acquiring sufficient data and putting susceptible patients at risk in the early stages of a development program, when little is known about a medicine's effects. Healthcare professionals and patients deserve to have access to clear information on the knowledge and evidence gaps leading to the approval of a new medicinal product. This should also include proper consideration of the population of older patients. In the present article, we outline the approach taken by the European Medicines Agency (EMA) regulators in the assessment of a new medicine's dossier.
