Final answer:
The combination of Azilsartan and Chlorthalidone includes an ARB and a diuretic, both used for treating high blood pressure. Together, they effectively lower blood pressure by different mechanisms.
Step-by-step explanation:
The combination of Azilsartan and Chlorthalidone refers to a medication regimen that includes both an angiotensin II receptor blocker (ARB) and a thiazide-like diuretic. Azilsartan falls under the category of ARBs, which also includes drugs like Losartan and Valsartan. These medications are often used to treat high blood pressure by blocking the effects of angiotensin II, which can cause blood vessels to tighten and raise blood pressure. On the other hand, Chlorthalidone is a diuretic, like Hydrochlorothiazide or Furosemide, and it works by helping to remove excess fluid from the body, also lowering blood pressure. Combined, these two drugs are used to lower blood pressure more effectively than either would alone.
