Ziac contains which active ingredients?

Ziac is a combination medication that consists of bisoprolol and hydrochlorothiazide (HCTZ). This combination is typically used to treat hypertension, providing the benefits of a beta-blocker (bisoprolol) and a diuretic (HCTZ). Bisoprolol helps reduce heart rate and cardiac output, while hydrochlorothiazide helps decrease blood volume by promoting urination, leading to lower blood pressure.

The other combinations mentioned do not align with the components of Ziac. Each option features a different beta-blocker partnered with HCTZ, but only bisoprolol is the correct beta-blocker featured in Ziac. Therefore, the inclusion of bisoprolol and HCTZ in the answer underscores the importance of recognizing the specific formulations of medications when considering their therapeutic effects.
