Side effects of antipsychotics in the elderly

Area of Science:

• Geriatric Medicine
• Psychopharmacology
• Clinical Pharmacy

Background:

• Antipsychotic medications are crucial for managing schizophrenia and other psychiatric conditions.
• Elderly patients exhibit unique physiological changes that can alter drug metabolism and increase susceptibility to side effects.
• Comorbidities like cardiovascular disease and dementia are common in older adults, complicating polypharmacy.

Purpose of the Study:

• To review the side effect profiles of antipsychotic medications in the elderly.
• To highlight age-related factors exacerbating medication adverse events.
• To discuss the implications of polypharmacy and differing stakeholder perspectives on side effects.

Main Methods:

• Literature review of antipsychotic side effects in geriatric populations.
• Analysis of age-related physiological changes impacting drug response.
• Consideration of common comorbidities and polypharmacy in elderly patients with schizophrenia.

Main Results:

• Key side effects of concern include anticholinergic reactions, parkinsonism, tardive dyskinesia, orthostatic hypotension, cardiac issues, bone density reduction, sedation, and cognitive slowing.
• Elderly patients are at higher risk for these adverse events due to physiological changes.
• Polypharmacy significantly increases the risk of drug interactions and adverse events.

Conclusions:

• Antipsychotic medication management in the elderly requires careful consideration of age-specific vulnerabilities and comorbidities.
• A thorough understanding of potential side effects and drug interactions is essential for safe and effective treatment.
• Addressing the diverse perspectives of patients, caregivers, and families is crucial for optimizing care.
