Summary
Elderly patients face higher risks of side effects from antirheumatic drugs due to altered metabolism and polypharmacy. Central nervous system toxicity is a common, overlooked issue in geriatric patients on these medications.
Area of Science:
- Geriatric Pharmacology
- Rheumatology
- Clinical Toxicology
Background:
- Elderly individuals often experience altered drug metabolism, polypharmacy, and multiple comorbidities.
- These factors significantly increase the risk of adverse drug reactions in patients undergoing antirheumatic therapy.
Purpose of the Study:
- To review the geriatric presentation of central nervous system (CNS) toxicity associated with antirheumatic drugs.
- To provide practical guidance for avoiding prescribing errors in elderly patients.
Main Methods:
- Literature review focusing on CNS toxicity in elderly patients treated with antirheumatic medications.
- Analysis of common risk factors including altered pharmacokinetics and self-medication errors.
Main Results:
- Central nervous system (CNS) toxicity is a frequent yet often unrecognized complication in older adults on antirheumatic drugs.
- Specific drug classes commonly used in rheumatology carry distinct risks for geriatric CNS toxicity.
Conclusions:
- Antirheumatic drug prescribing in the elderly requires careful consideration of age-related physiological changes and potential drug interactions.
- Awareness and proactive management of CNS toxicity are crucial for improving patient safety and therapeutic outcomes in geriatric rheumatology.
