Medication use in the elderly patient: focus on the perioperative/perianesthesia setting

As the population ages, the use of multiple medications also increases. Polypharmacy (taking multiple drugs at a time) presents concerns to the perianesthesia nurse who is caring for the geriatric patient. The pharmacokinetics and pharmacodynamics of drugs are often altered in older adult patients. Adverse drug reactions and drug interactions occur more often in geriatric patients than in younger patients. For these reasons, the benefits and risks of multiple medications and the administration of certain types of drugs must be carefully considered in the elderly patient. The selection of any medication should be individually based on the benefits and risks. Adverse drug reactions play a significant role in hospitalization for the general population, and the elderly are more susceptible to these. These drug reactions often contribute to significant morbidity as well as mortality. Medications need to be considered carefully in the older adult patient, but perhaps more so in the perioperative/perianesthesia period. Drug interactions are diverse. The type of anesthesia may influence the patient's outcome, depending on the medications the patient is currently taking. The patient's response to the stress of surgery is also affected by individual medical conditions as well as medications the patient is currently receiving Polypharmacy, inappropriate medications, adverse drug reactions, drug-disease issues, and drug interactions in the geriatric population are concerns in the perioperative/perianesthesia setting.
