Multiple medication: problems of the elderly patient.

Area of Science:

• Geriatric Medicine
• Clinical Pharmacology
• Pharmacotherapy

Background:

• Elderly individuals frequently manage multiple chronic conditions, leading to polypharmacy.
• Physiological changes in aging (liver, kidney, brain function) alter drug metabolism and response.
• Self-medication with prescription and over-the-counter drugs complicates geriatric pharmacotherapy.

Purpose of the Study:

• To highlight the unique challenges in prescribing medications for elderly patients.
• To emphasize the increased risk of adverse drug reactions (ADRs) and drug interactions in this population.
• To provide guidance on optimizing drug therapy for older adults.

Main Methods:

• Review of physiological changes affecting drug disposition in the elderly.
• Analysis of common drug classes associated with increased risk in older adults.
• Discussion of strategies for safe prescribing and medication management in geriatrics.

Main Results:

• Elderly patients exhibit unpredictable responses to various drug classes, including antibiotics, anticoagulants, antiarrhythmics, benzodiazepines, and opioids.
• Adverse drug reactions are often severe and rapid in onset.
• Anesthetic agents can pose significant risks to the elderly central nervous system and liver.

Conclusions:

• Prescribers must exercise extreme caution with medication choices and dosages in patients over 65-70 years.
• Prioritize drugs with broad therapeutic ratios and specific actions; avoid those with narrow therapeutic indices.
• Regular patient monitoring and frequent review of medication necessity are essential to minimize risks and maximize benefits.
