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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

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...

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...

Allergic Reactions: Anaphylaxis

Allergic Reactions: Anaphylaxis

Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin,...

Summary

This summary is machine-generated.

Older adults show distinct contact allergen profiles, with higher rates of fragrance mix and Balsam of Peru sensitization. Leg dermatitis is also more common in this age group.

Area of Science:

Dermatology
Allergology
Epidemiology

Context:

The aging population presents unique dermatological challenges.
Lifelong exposures and comorbidities influence sensitization in seniors.
Analysis of the IVDK cohort (2009-2013, N=14,841) compared allergen profiles in individuals >65 years vs. ≤65 years.

Purpose:

To identify differences in contact allergen sensitization profiles between older adults (>65 years) and younger individuals (≤65 years).
To investigate the impact of comorbidities like leg dermatitis on allergen sensitization in seniors.

Summary:

Top allergens in seniors (>65) include fragrance mix, Balsam of Peru, nickel sulfate, fragrance mix II, colophony, propolis, MCI/MI, lanolin alcohol, Amerchol L 101, and tert-butylhydroquinone.
Sensitization to nickel was less frequent in seniors, while fragrance mix and Balsam of Peru were more frequent compared to younger individuals.
Leg dermatitis affected 25.9% of seniors vs. 5.8% of younger individuals. Specific sensitivities to topical ointment ingredients (lanolin alcohol, Amerchol L 101, tert-butylhydroquinone) differed in seniors with leg-related comorbidities.

Impact:

Findings highlight the need for tailored patch testing strategies in older adults, particularly those with leg dermatitis.
Results inform clinical practice regarding common allergens and comorbidities in geriatric dermatology.
Understanding age-related sensitization patterns can improve diagnosis and management of allergic contact dermatitis in the elderly.
