Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

217
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...

Drug Therapy01:28

Drug Therapy

237
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Pharmacodynamics in Geriatric Patients: Effects of Age01:27

Pharmacodynamics in Geriatric Patients: Effects of Age

182
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...

Alzheimer's Disease: Treatment

801
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

245
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Dosage Regimen: Individualization01:24

Dosage Regimen: Individualization

161
Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Area of Science:

  • Gerontology
  • Pharmacology
  • Public Health

Background:

  • Persons with dementia (PWD) frequently struggle with medication management, leading to medication deviations.
  • These deviations can increase the risk of adverse drug events and hospitalizations.

Purpose of the Study:

  • To identify and summarize factors influencing medication deviations in PWD.
  • To provide references for enhancing medication management strategies in this population.

Main Methods:

  • A scoping review methodology was employed.
  • Literature search conducted across six databases for studies published between January 1, 2015, and March 1, 2025.
  • Included cross-sectional and cohort studies investigating medication deviations in PWD.

Main Results:

  • Twenty-one studies were included in the review.
  • Common assessment tools included the Beers Criteria® and STOPP criteria.
  • Risk factors were categorized into individual, caregiver, and medication-related domains.
  • Potentially inappropriate medications were the most prevalent deviation type, with rates from 12.2% to 85%.

Conclusions:

  • Medication deviations are widespread in individuals with dementia.
  • Strengthening medication management through reviews, caregiver education, and multidisciplinary approaches is crucial.
  • Future research should focus on standardized tools and dementia-specific strategies.
