As people age, changes in drug handling increase adverse drug reactions in elderly patients. Understanding these physiological changes can improve prescribing practices and patient safety.

Area of Science:

  • Geriatric Medicine
  • Clinical Pharmacology
  • Pharmacokinetics

Background:

  • The proportion of individuals over 65 is increasing globally.
  • Elderly patients are more susceptible to adverse drug reactions (ADRs).
  • Inappropriate prescribing, due to incomplete understanding of age-related changes in drug handling, contributes to ADRs.

Purpose of the Study:

  • To review the clinical consequences of age-related changes in drug handling.
  • To identify areas for improved prescribing practices in the elderly.
  • To reduce the incidence of adverse drug reactions in older adults.

Main Methods:

  • Literature review focusing on physiological changes with aging.
  • Analysis of age-related alterations in pharmacokinetics and pharmacodynamics.

  • Synthesis of clinical data on adverse drug reactions in the elderly.

    • Main Results:

    • Physiological changes in aging significantly alter drug absorption, distribution, metabolism, and excretion.
    • These alterations can lead to increased drug toxicity and reduced efficacy.
    • Current prescribing practices often do not adequately account for these age-specific changes.

    Conclusions:

    • A deeper understanding of geriatric pharmacokinetics is crucial for safe and effective drug therapy.
    • Modifications in prescribing practices are needed to mitigate risks in elderly patients.
    • Optimizing drug selection and dosage can improve clinical outcomes and reduce ADRs in the aging population.
