in the US and their dosages, adverse effects, and costs are listed in the tables. Treatment of hypertensive urgencies and emergencies is not discussed here.

Most recent guidelines recommend a BP goal of 140/90 mm Hg. For patients ≥60 years old without diabetes or chronic kidney disease, one guideline recommends 150/90 mm Hg both as the drug treatment initiation threshold and treatment target; this higher target is controversial, except in patients ≥80 years old.

The FDA has approved aliskiren/amlodipine/hydrochlorothiazide (Amturnide) for treatment of hypertension, with no restrictions except that it should not be used for initial therapy. A combination of the direct renin inhibitor aliskiren and the calcium channel blocker amlodipine (Tekamlo) was approved earlier for initial treatment.1

Use of combination tablets is, of course, more convenient than taking the components separately, and as long as all the same doses are available and the cost is no greater, there is no reason not to use them.

Aliskiren alone or in combination has not been shown to improve clinical outcomes.2 Whether it offers any advantage over the angiotensin receptor blockers (ARBs), which are also available in various antihypertensive combinations, remains to be determined.
