Aliskiren (INN) (trade names Tekturna, US; Rasilez, UK and elsewhere) is the first in a class of drugs called direct renin inhibitors. Its current licensed indication is essential (primary) hypertension.

Aliskiren was co-developed by the Swiss pharmaceutical companies Novartis and Speedel.[1][2] It was approved by the US Food and Drug Administration in 2007 for the treatment of primary hypertension.[3]

In December 2011, Novartis had to halt a clinical trial of the drug after discovering increased incidence of nonfatal stroke, renal complications, hyperkalemia, and hypotension in patients with diabetes and renal impairment (ALTITUDE Trial ).[4] [5]

As a result, in April 20, 2012:

  • A new contraindication was added to the product label concerning the use of aliskiren with angiotensin receptor blockers (ARBs) or angiotensin-converting enzyme inhibitors (ACEIs) in patients with diabetes because of the risk of renal impairment, hypotension, and hyperkalemia.
  • A warning to avoid use of aliskiren with ARBs or ACEIs was also added for patients with moderate to severe renal impairment (i.e., where glomerular filtration rate is less than 60 ml/min).
