What is the primary active ingredient in Azor?

Azor is a combination medication primarily used to treat high blood pressure, and its active ingredients include amlodipine and telmisartan. Among these, amlodipine is the calcium channel blocker that works by relaxing blood vessels and improving blood flow, making it a key component of this medication.

While telmisartan, also present in Azor, is an angiotensin receptor blocker that also helps lower blood pressure, the active ingredient that plays a notable role in the combination formulation, especially in the context of controlling and managing hypertension, is amlodipine. This synergy enhances the effectiveness of blood pressure control.

The other options provided do not pertain to the primary active components of Azor; atorvastatin is primarily used for lowering cholesterol, and HCTZ, or hydrochlorothiazide, is a diuretic that is sometimes used in other blood pressure medications but is not an active ingredient in Azor.
