Pharmacokinetic changes in aging.

The American Journal of Medicine

|May 16, 1986

Summary

This summary is machine-generated.

Elderly patients require careful drug management due to physiological changes affecting drug pharmacokinetics and pharmacodynamics. This review details age-related physiological shifts and their impact on drug therapy, including oral hypoglycemics for diabetes.

Background:

Aging significantly alters drug pharmacokinetics and pharmacodynamics.
Multiple factors like lifestyle, comorbidities, and polypharmacy complicate drug therapy in older adults.
Physiological changes with age impact drug absorption, distribution, metabolism, and excretion.

Purpose of the Study:

To review age-related physiological changes affecting drug disposition.
To relate these physiological changes to the clinical use of common drugs in the elderly.
To guide the selection of oral hypoglycemic agents for elderly diabetic patients based on pharmacokinetic properties.

Main Methods:

Literature review of physiological changes associated with aging.

Analysis of how these changes affect drug pharmacokinetics and pharmacodynamics.

Examination of clinical factors influencing drug response in the elderly.

Review of pharmacokinetic properties of oral hypoglycemic agents.

Main Results:

Aging alters drug absorption, distribution, metabolism, and excretion.
Clinical factors can modify or enhance age-related physiological effects on drug response.
Pharmacokinetic profiles of oral hypoglycemic agents vary, influencing optimal selection for elderly diabetics.

Conclusions:

Optimizing drug therapy in the elderly necessitates understanding age-related physiological changes.
Individualized drug selection and monitoring are crucial for safe and effective treatment in older adults.
Pharmacokinetic considerations are vital for choosing appropriate oral hypoglycemic agents in elderly diabetic patients.
