Geriatric pharmacology for the dentist. An overview

Area of Science:

• Geriatric Pharmacology
• Dental Drug Therapy
• Aging and Drug Metabolism

Background:

• Aging significantly impacts drug pharmacokinetics, often prolonging drug half-life and delaying clearance.
• Pharmacodynamic changes in the elderly are variable, affecting sensitivity to different drug classes.
• Elderly individuals frequently have multiple comorbidities and a higher likelihood of polypharmacy, increasing risks.

Purpose of the Study:

• To review the complex effects of aging on drug responses relevant to dental practice.
• To provide guidance for dentists managing medication in geriatric patients.
• To highlight the importance of understanding age-related drug alterations and interactions.

Main Methods:

• Review of existing literature on geriatric pharmacokinetics and pharmacodynamics.
• Analysis of factors influencing drug response in the elderly, including compliance and comorbidities.
• Discussion of practical implications for dental drug prescription and patient management.

Main Results:

• Elderly patients may show increased sensitivity to depressant drugs (e.g., benzodiazepines, anesthetics) and neuromuscular blockers, necessitating dosage reduction.
• Reduced sensitivity to pain in geriatric individuals may require lower analgesic doses.
• Altered homeostasis and increased risk of drug interactions and adverse reactions are common in the elderly due to polypharmacy.

Conclusions:

• Dentists must exercise caution and adjust drug dosages for elderly patients based on age-related physiological changes.
• Continuous awareness of a patient's complete medication regimen is critical to prevent adverse drug events and interactions.
• Personalized medication management is essential for safe and effective dental treatment in geriatric populations.
