Escalating polypharmacy

New drug treatments, new indications for older drug treatments, lower thresholds for treating risk factors in preventative medicine, and an ageing population acquiring multiple pathologies all contribute to the development of polypharmacy. Longitudinal studies document the rise in prescribed medications, particularly in the elderly. The potential dangers of adverse drug reactions and interactions, poor adherence and confusion associated with ever-increasing polypharmacy are likely to worsen. Strategies to reduce prescribing will obviously decrease the dangers of polypharmacy. These include more considered prescribing when contemplating additions to patients' already lengthy prescription lists, and external reviews of medicine lists by a doctor or pharmacist. Despite such strategies, polypharmacy seems inevitable and considerations must be given to simplifying patients' multiple drug administrations using single-daily-dose regimens, fixed-dose combination pills, calendar-blister packaging and pill organizers.
