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...

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...

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...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
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...

Area of Science:

  • Nephrology
  • Geriatrics
  • Internal Medicine

Background:

  • Increasing prevalence of chronic kidney disease (CKD) globally.
  • Elderly patients with CKD exhibit distinct clinical features and complications.
  • Age-related issues like malnutrition, cognitive impairment, and physical dependence are common in elderly CKD patients.

Purpose of the Study:

  • To highlight the emergence and importance of geriatric nephrology.
  • To emphasize the need for specialized care considering the unique profile of elderly CKD patients.
  • To underscore the impact of comorbidities like diabetes and vascular disease on prognosis.

Main Methods:

  • Review of clinical features and complications in elderly CKD patients.
  • Consideration of age-specific factors such as malnutrition, cognitive status, and functional dependence.
  • Analysis of the role of comorbidities (diabetes, vascular disease) in prognosis.
  • Emphasis on comprehensive patient evaluation including quality of life.

Main Results:

  • Geriatric nephrology has emerged to address the specific needs of older adults with CKD.
  • High prevalence of diabetes and vascular disease in the elderly CKD population is linked to poor prognosis, particularly cerebrocardiovascular mortality.
  • Comprehensive assessment, including quality of life, is crucial for treatment decisions.

  • Geriatric nephrology requires a holistic approach to manage elderly patients with CKD.
  • Accurate patient evaluation and tailored therapeutic strategies are essential.
  • Judicious use of medications is critical in this vulnerable population to improve outcomes and reduce mortality.
