Summary
Elderly patients on multiple medications face higher risks due to unique physiological factors. Inappropriate prescribing, not just polypharmacy, causes adverse drug events in older adults.
Area of Science:
- Geriatrics
- Clinical Pharmacology
- Internal Medicine
Context:
- Elderly patients with chronic diseases often experience polypharmacy.
- Physiological changes in older adults increase vulnerability to medications.
- Limited clinical trial data complicates benefit/risk assessment in this population.
Purpose:
- To highlight the risks of polypharmacy and iatrogenicity in the elderly.
- To emphasize the need for careful drug prescription and review in older patients.
- To differentiate between polypharmacy and inappropriate prescribing.
Summary:
- Polypharmacy in elderly patients with chronic conditions can lead to adverse events due to pharmacokinetic and pharmacodynamic differences.
- Iatrogenicity is common, necessitating physician consideration of drug effects for unexplained health changes.
- Careful initiation and discontinuation of medications are crucial, focusing on avoiding inappropriate prescriptions rather than polypharmacy itself.
Impact:
- Physicians should actively consider drug adverse effects for unexplained health issues in the elderly.
- Rational drug prescription, including deprescribing, is essential for patient safety.
- This understanding can reduce iatrogenic complications and improve pharmacotherapy outcomes in geriatric populations.

Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
365
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
377
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

849
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
393
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
