Question 16

Celexa and Paxil represent a therapeutic duplication.

Both Celexa and Paxil are selective serotonin reuptake inhibitors (SSRIs) used to treat depression and anxiety disorders, making their concurrent use a case of therapeutic duplication.

A) Celexa and Paxil

This option is correct as both medications belong to the same class of antidepressants (SSRIs) and serve similar therapeutic purposes. Using both simultaneously could increase the risk of side effects without providing additional therapeutic benefit.

B) Celexa and Toprol XL

Celexa is an SSRI used for depression, while Toprol XL is a beta-blocker used for hypertension and heart conditions. These medications do not duplicate each other's therapeutic effects, making this option incorrect.

C) Ditropan XL and Paxil

Ditropan XL is an anticholinergic medication used to treat overactive bladder, while Paxil is an SSRI for depression and anxiety. There is no therapeutic duplication between these two, thus this option is incorrect.

D) Ditropan XL and Toprol XL

Ditropan XL and Toprol XL serve different therapeutic purposes—Ditropan for bladder control and Toprol XL for heart conditions. As such, there is no overlap or duplication in their uses, making this option incorrect.

Conclusion

Celexa and Paxil are the only pair that exemplifies therapeutic duplication due to their classification as SSRIs and similar therapeutic uses. In contrast, the other options involve medications with distinct mechanisms and indications, highlighting the importance of understanding drug classes and their appropriate applications in therapy.
