Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

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...

Pharmacodynamics in Geriatric Patients: Effects of Age

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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

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...
Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

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...
Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution01:00

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

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 not...
Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

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...

    Summary

    Family physicians and residents reported challenges treating elderly patients, including communication and time constraints. Enhanced geriatric education is recommended to improve care and prevent physician pessimism.

    Area of Science:

    • Geriatric Medicine
    • Medical Education
    • Family Medicine

    Background:

    • Physician attitudes and experiences with elderly patients are crucial for effective geriatric care.
    • Understanding training gaps in geriatrics is essential for improving healthcare for older adults.

    Purpose of the Study:

    • To assess the experiences and attitudes of family physicians and residents regarding geriatric patients.
    • To identify challenges in treating the elderly and perceived needs for specialized geriatric training.

    Main Methods:

    • A study involving 180 family physicians and residents.
    • Data collection focused on physician experience, attitudes, and perceived problems in geriatric care.

    Main Results:

    Oral Health Assessment by Lay Personnel for Older Adults

    Published on: February 2, 2020

  • Older physicians reported a higher volume of geriatric patients.
  • Residents expressed more dissatisfaction with geriatric care compared to established physicians.
  • Key challenges identified include communication barriers, inadequate medical education, and insufficient time.
  • Residents more frequently recognized the need for geriatric specialists.

    • Conclusions:

    • Physician age or experience did not correlate with pessimism towards geriatric patients.
    • Enhanced geriatric education at all training levels is vital to foster positive attitudes and prevent therapeutic pessimism.
