Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

219
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

183
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 Metabolism

194
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

223
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

232
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...

Area of Science:

  • Forensic Criminology
  • Gerontology
  • Geriatric Psychiatry

Background:

  • Limited research exists on crimes committed by the elderly population.
  • Understanding elderly offender characteristics is crucial for developing targeted prevention strategies.
  • This study addresses the gap in knowledge regarding elderly perpetrators of homicide.

Purpose of the Study:

  • To profile elderly homicide offenders.
  • To identify demographic, motivational, and situational characteristics of elderly killers.
  • To provide recommendations for homicide prevention in the geriatric population.

Main Methods:

  • Analysis of demographic data, crime motivations, crime scenes, homicide methods, weapons, psychiatric diagnoses, and perpetrator-victim relationships.
  • Study population: elderly offenders (aged ≥65) undergoing forensic evaluation.
  • Data collected from 2011 to 2021 at the Fourth Specialization Board of the Council of Forensic Medicine of Turkey.

Main Results:

  • The majority of offenders (95%) were male, aged 65-87 years.
  • Most elderly offenders had low educational attainment, and homicides frequently occurred at home (46%).
  • Firearms were the most common weapon; 26.7% killed their spouses, and 8.9% had schizophrenia.

Conclusions:

  • Findings offer insights into the profile of elderly homicide offenders.
  • Recommendations include educating healthcare professionals, monitoring the geriatric population, and enhancing mental health awareness.
  • Strengthening social support services is anticipated to reduce homicide rates among older adults.
