Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

193
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...

Cognitive Development During Adulthood

728
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Pharmacodynamics in Geriatric Patients: Effects of Age

168
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 Excretion

211
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 Absorption

199
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 Metabolism

171
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...

Area of Science:

  • Geriatric Medicine
  • Orthopedics
  • Neurology

Background:

  • Frailty and cognitive dysfunction are prevalent in elderly orthopedic patients.
  • The interplay between frailty and cognitive decline requires further investigation in emergency settings.

Purpose of the Study:

  • To analyze the prevalence of frailty and cognitive dysfunction in elderly patients presenting to an orthopedic emergency department.
  • To investigate the correlation between frailty status and cognitive function in this population.

Main Methods:

  • A cohort of 248 elderly patients (≥65 years) in an orthopedic emergency department were assessed.
  • Cognitive function was evaluated using the Mini-Mental State Examination (MMSE); frailty was assessed using the FRAIL scale.
  • Additional assessments included ADL, exercise tolerance, grip strength, and Geriatric Nutritional Risk Index (GNRI).

Main Results:

  • Prevalence rates for cognitive impairment ranged from mild cognitive impairment (MCI) to severe dementia.
  • Significant associations were found between frailty, prefrailty, and cognitive dysfunction.
  • Factors such as age, education level, hypertension, COPD, cerebral infarction, and GNRI influenced frailty, while frailty, ADL, exercise tolerance, and grip strength impacted cognitive function.

Conclusions:

  • Prefrailty and frailty are significant risk factors for cognitive dysfunction in elderly patients within an orthopedic emergency context.
  • These findings highlight the need for integrated screening and management of both frailty and cognitive health in this demographic.
