Question 24

Prescribing two different beta-blockers for hypertension is an example of a therapeutic duplication.

Therapeutic duplication occurs when a patient is prescribed more than one medication that serves the same therapeutic purpose. In this case, using two different beta-blockers for hypertension provides redundant treatment, which can increase the risk of side effects without offering additional benefits.

A) Prescribing ibuprofen and acetaminophen together

This option is incorrect because ibuprofen and acetaminophen serve different mechanisms of action for pain relief and can be safely used together to manage pain and fever. This combination does not constitute therapeutic duplication, as they do not overlap in their therapeutic effects.

B) Prescribing two different statins for cholesterol

While prescribing two different statins may seem like a duplication, it can be clinically justified in certain situations, such as when a patient's cholesterol levels are not adequately controlled on a single statin. Thus, this does not fit the strict definition of therapeutic duplication, which involves medications of the same class used for the same condition.

C) Prescribing two different beta-blockers for hypertension

This option is correct as it exemplifies therapeutic duplication. Beta-blockers are used to treat hypertension, and prescribing two different ones does not provide additional therapeutic benefit while increasing the risk of adverse effects, making it a clear case of duplication.

D) Prescribing two different ACE inhibitors for heart failure

This is incorrect as ACE inhibitors, while both treating the same condition, are typically not prescribed together due to the risk of adverse effects and lack of additional benefit. The use of two different ACE inhibitors does not align with therapeutic duplication but rather with inappropriate medication management.

Conclusion

Prescribing two different beta-blockers for hypertension clearly represents a case of therapeutic duplication, as it involves overlapping classes of medications that aim to treat the same condition without added benefit. Other options demonstrate either safe combination therapies or inappropriate prescribing practices, but they do not meet the criteria of therapeutic duplication as defined in this context.
