What is a key consideration when prescribing medication to elderly patients?

When considering medication for elderly patients, a crucial factor is that they often experience altered drug metabolism and absorption. As individuals age, physiological changes can significantly impact how their bodies process medications. For example, the liver's ability to metabolize drugs may decline, and renal function may decrease, affecting how quickly drugs are eliminated. Additionally, the gastrointestinal system may undergo changes that affect drug absorption. This variability in drug metabolism can lead to both increased sensitivity to medications and a greater risk of side effects, making it essential to consider these factors when prescribing.

This understanding informs clinicians to choose dosages carefully and monitor responses more closely, as the standard doses used in younger populations may not be appropriate for older adults. Recognizing the altered pharmacokinetics and pharmacodynamics in the elderly is vital for optimizing their treatment and ensuring safety.
