What is an important consideration when administering medication to elderly patients?

When administering medication to elderly patients, it is essential to recognize that they often experience altered pharmacokinetics. Pharmacokinetics refers to how the body absorbs, distributes, metabolizes, and excretes drugs. In elderly individuals, various physiological changes such as reduced liver and kidney function can affect these processes. Consequently, this population may require dosage adjustments to avoid under-treatment or over-treatment.

For instance, decreased renal function can lead to slower clearance of medications, increasing the risk of toxicity if standard dosages are used. Similarly, changes in body composition, such as increased fat and decreased lean body mass, can influence drug distribution and action.

Overall, understanding the unique pharmacokinetic challenges faced by elderly patients is crucial for safe and effective medication administration. This consideration helps to optimize therapeutic outcomes and minimize the risk of adverse effects.
