Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

395
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

367
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

861
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 Excretion

354
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

382
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...

Summary

Ethnic elders in the U.S. are a rapidly growing population with diverse healthcare needs. Geriatric education must address these unique health risks, beliefs, and service utilization patterns for better care.

Area of Science:

  • Geriatrics
  • Public Health
  • Minority Health

Background:

  • The U.S. older adult population is rapidly expanding.
  • Ethnic minority populations represent a fast-growing segment of older adults.
  • Current geriatric education inadequately addresses the diverse needs of ethnic elders.

Purpose of the Study:

  • To highlight the growing need for ethnogeriatric education.
  • To inform the development of culturally sensitive geriatric care.
  • To address disparities in healthcare for ethnic elders.

Main Methods:

  • Reviewing diverse health risks among ethnic elders.
  • Analyzing varied health beliefs and treatment expectations.
  • Examining unique healthcare utilization patterns.

  • Developing ethnogeriatric curriculum content.

    • Main Results:

    • Ethnic elders exhibit significant diversity in health risks and beliefs.
    • Healthcare-seeking behaviors and service utilization vary widely.
    • Existing geriatric training lacks sufficient focus on ethnogeriatric competencies.
    • Stanford Geriatric Education Center is developing targeted curriculum.

    Conclusions:

    • Ethnogeriatric education is crucial for addressing the needs of a growing demographic.
    • Culturally competent geriatric care requires specialized training.
    • Curriculum development is essential to prepare providers for diverse elder populations.
