Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

344
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

312
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

310
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 Distribution

326
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

797
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 Metabolism01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

314
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...

Summary

External visible changes and laboratory tests help determine old age in dogs. Hematological and biochemical evaluations, along with urine analysis, are crucial for managing geriatric canine health and identifying common age-related issues like anemia and kidney dysfunction.

Area of Science:

  • Veterinary Medicine
  • Geriatric Care
  • Canine Health

Background:

  • Aging in dogs presents unique health challenges requiring specific management strategies.
  • Assessing geriatric canine health involves evaluating physical, hematological, biochemical, and urinalysis parameters.

Purpose of the Study:

  • To establish criteria for identifying old age in dogs.
  • To analyze hematological, biochemical, and urine alterations in geriatric dogs.
  • To correlate these findings with the management of senile canine conditions.

Main Methods:

  • Utilized a standard geriatric age chart for screening dogs.
  • Assessed external markers: hair coat, dental wear, skin, and glaucoma.
  • Conducted hematology, serum biochemistry, and urinalysis.

Main Results:

  • Common findings included greying hair, osteoarthritis, and dental wear.
  • Decreased hemoglobin, erythrocyte count, and packed cell volume observed.
  • Urinalysis revealed abnormalities such as protein, glucose, and bacteria, indicating potential kidney dysfunction.

Conclusions:

  • External changes are key indicators of canine old age.
  • Hematological and biochemical data aid in understanding pathophysiological status.
  • Urine analysis is vital for detecting geriatric kidney problems, with anemia and nephritis being common concerns.
