Pharmacodynamics in Geriatric Patients: Effects of Age

Pharmacodynamics in Geriatric Patients: Effects of Age

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 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 Obstructive Pulmonary Disease-V: Management

Chronic Obstructive Pulmonary Disease-V: Management

Managing Chronic Obstructive Pulmonary Disease (COPD) involves a multifaceted approach to reduce symptoms, prevent exacerbations, improve overall health status, and slow disease progression. Key strategies include lifestyle modifications, pharmacotherapy, supportive therapies, and, in some cases, surgery. Here is an overview of the primary COPD management strategies:

Drug Dosing: Geriatric Patients

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...

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

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...

Summary

It is never too late to quit smoking. Older smokers (≥60) achieved similar smoking cessation rates to younger smokers (<60) when receiving standard treatment. This challenges the notion that age is a barrier to quitting.

Background:

Older smokers are often discouraged from quitting due to misconceptions about age-related efficacy of interventions.
This study addresses the erroneous belief that it is too late for older individuals to successfully quit smoking.

Purpose of the Study:

To compare smoking cessation rates between older (≥60 years) and younger (<60 years) adult smokers.
To determine if advanced age is a significant obstacle to successful smoking cessation.

Main Methods:

A cohort of 987 smokers received standardized behavioral therapy and pharmacotherapy at a Brazilian smoking cessation clinic.
Participants were categorized into two age groups: <60 years and ≥60 years.
Smoking abstinence was verified via exhaled carbon monoxide levels (<10 ppm) at 2, 6, and 12 months post-treatment.

Main Results:

Abstinence rates at 12 months were 43.5% for younger smokers and 53.3% for older smokers.
The difference in quit rates between age groups was not statistically significant (P=0.073 via log rank test; adjusted Hazard Ratio 0.90, P=0.48 via Cox regression).
Older smokers demonstrated comparable success in quitting smoking to their younger counterparts.

Conclusions:

Smoking cessation interventions are effective in older adults, yielding similar abstinence rates to younger individuals.
These findings support the integration of smoking cessation programs for all age groups, particularly in low- and middle-income countries.
Age should not be considered a barrier to smoking cessation treatment.
