Drug Dosing: Geriatric Patients01:15

Drug Dosing: Geriatric Patients

337
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

779
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 Distribution

307
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...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.0K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Bone Disorders

5.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Aging01:26

Aging

929
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Summary
This summary is machine-generated.

Adequate antioxidant intake is crucial for healthy aging, protecting against age-related diseases. Dietary antioxidants, like vitamins C and E, combat oxidative stress and support cardiovascular and immune health in older adults.

Area of Science:

  • Gerontology
  • Nutritional Science
  • Biochemistry

Background:

  • Inadequate nutrition in mature and aged populations contributes to pathological senescence.
  • Oxidative stress, linked to reactive oxygen species (ROS), plays a key role in age-related cardiovascular and immune system decline.

Purpose of the Study:

  • To review the role of antioxidants in mitigating age-related oxidative stress.
  • To highlight the protective effects of dietary antioxidants on cardiovascular and immune functions in aging.

Main Methods:

  • Literature review of nutritional research on aging laboratory animals and human studies.
  • Analysis of experimental and clinical data on antioxidant interventions.

Main Results:

  • Dietary restriction shows promise in extending lifespan and healthspan in animal models by reducing oxidative stress.
  • Antioxidant vitamins C and E, along with specific thiolic and phenolic compounds, demonstrate protective effects against age-related cardiovascular and immune dysfunction.
  • Preventing vitamin E deficiency and thiol pool oxidation may protect against atherogenesis and immune decline.

Conclusions:

  • Oxygen free radicals are central to the pathology of normal aging and age-related diseases.
  • Sufficient dietary antioxidant consumption is essential for maintaining health in old age.
  • Targeted antioxidant strategies can offer protection against age-related atherogenesis and immune dysfunction.
