Summary
Elderly patients face increased drug risks due to reduced kidney function. This review highlights common medications like NSAIDs and ACE inhibitors that can cause adverse drug reactions in older adults.
Area of Science:
- Nephrology
- Geriatric Medicine
- Pharmacology
Background:
- The kidney's high blood flow and metabolic activity make it susceptible to xenobiotic injury.
- Age-related decline and comorbidities in elderly patients often impair renal function.
- Reduced renal function in the elderly increases the risk of adverse drug reactions (ADRs) and systemic drug accumulation.
Purpose of the Study:
- To review drug-induced kidney injury and adverse drug reactions in the elderly.
- To emphasize the risks associated with commonly prescribed medications in older adults.
- To provide insights into managing medication safety in geriatric populations.
Main Methods:
- Literature review focusing on drug-induced nephrotoxicity.
- Analysis of studies concerning medication use in elderly patients.
- Emphasis on specific drug classes frequently used in geriatric care.
Main Results:
- Elderly individuals are at higher risk for kidney damage from medications.
- Commonly used drugs like NSAIDs, ACE inhibitors, antibiotics, and immunosuppressants pose significant risks.
- Drug accumulation due to impaired renal function can lead to both nephrotoxicity and extra-renal ADRs.
Conclusions:
- Careful consideration of renal function is crucial when prescribing medications to the elderly.
- Monitoring for adverse drug reactions is essential, particularly with drugs affecting kidney function.
- Optimizing medication regimens can mitigate risks and improve patient outcomes in geriatric populations.
