Question 58

Hyzaar contains hydrochlorothiazide and losartan.

Hyzaar is a combination medication that includes hydrochlorothiazide and losartan. This combination is used to treat high blood pressure effectively.

A) irbesartan.

Irbesartan is not a component of Hyzaar. Instead, it is a standalone medication used to treat hypertension, but it does not combine with hydrochlorothiazide in the formulation known as Hyzaar.

B) losartan.

Losartan is the correct answer as it is the component of Hyzaar that combines with hydrochlorothiazide. This combination works synergistically to lower blood pressure by both reducing fluid retention and relaxing blood vessels.

C) olmesartan.

Olmesartan is not present in Hyzaar. It is another antihypertensive medication that is used on its own or in other combinations but does not include hydrochlorothiazide as part of its formulation.

D) valsartan.

Valsartan is also not an ingredient in Hyzaar. Similar to irbesartan and olmesartan, valsartan is used for hypertension but does not combine with hydrochlorothiazide in this particular medication.

Conclusion

The correct answer is B) losartan, as it is the only option that accurately identifies the second active ingredient in Hyzaar. All other options fail to represent the composition of Hyzaar, as they are distinct medications used for hypertension but do not form part of this specific combination.
