Which factor should a doctor consider when prescribing beta-2 agonists to elderly patients?
Understand the Problem
The question asks about a specific consideration when prescribing beta-2 agonists, a type of medication, to elderly patients. It requires knowledge of how elderly patients might respond differently to this medication compared to younger adults, particularly focusing on factors like drug sensitivity, metabolism, and potential adverse effects.
Answer
Doctors should consider cardiovascular risks, altered drug pharmacokinetics, and potential for adverse effects when prescribing beta-2 agonists to elderly patients.
When prescribing beta-2 agonists to elderly patients, a doctor should consider the potential for increased heart rate, worsening of arrhythmia, and the possibility of precipitating ischemic events, especially in those with pre-existing conditions like COPD or heart failure. Altered medication pharmacokinetics and pharmacodynamics due to age-related changes should also be considered.

When prescribing beta-2 agonists to elderly patients, a doctor should consider the potential for increased heart rate, worsening of arrhythmia, and the possibility of precipitating ischemic events, especially in those with pre-existing conditions like COPD or heart failure. Altered medication pharmacokinetics and pharmacodynamics due to age-related changes should also be considered.
More Information
Beta-2 agonists are commonly used to treat conditions like asthma and COPD by relaxing the airways. However, they can have side effects, especially in older adults who may be more susceptible to cardiovascular issues.
Tips
A common mistake is to overlook the potential impact of age-related physiological changes on drug metabolism and effects. Always consider the patient's complete medical history and potential drug interactions.
