How does the absorption rate change in the elderly population?

In the elderly population, the absorption rate of medications can be affected by several physiological changes associated with aging. These changes can lead to variability in how drugs are absorbed in the gastrointestinal (GI) tract. Factors such as diminished gastric acidity, slower gastric emptying, reduced splanchnic blood flow, and variations in intestinal motility can all play a role in modifying drug absorption.

Therefore, stating that the absorption rate "changes" accurately reflects the complexity of these interactions. As elderly patients may experience altered absorption rates for different medications, understanding that this rate is variable and can either increase, decrease, or remain the same depending on various conditions is crucial for effective pharmacological management in this population. This awareness also highlights the importance of individualized medication management for older adults, considering their unique physiological characteristics.
