FDA Aliskiren New Warning and Contraindication

Federal regulators at the Food and Drug Administration (FDA) have issued a warning about the combination of blood pressure medication Aliskiren (Tekturna) with ACE inhibitors and angiotensin receptor blockers (ARBS) in diabetics or kidney patients.


Novartis, the maker of Aliskiren, announced that the TekturnaR labels have been updated in the US, following the FDA’s review of the preliminary findings from the ALTITUDE study.

Altitude Study

The ALTITUDE study, found an increased risk of adverse events in patients who were taking the direct renin inhibitor as an add-on to other anti-hypertensive medications such as ARBs and ACE inhibitors.

The FDA said that diabetic patients who mix the drugs are at risk of renal impairment, hypotension, and hyperkalemia.

Novartis, has decided to cease marketing in the US of ValturnaR (aliskiren and valsartan, USP), a single pill combination of aliskiren and the ARB valsartan. Valturna will no longer be marketed after July 2012.

Medications that contain aliskiren include:

Amturnide (aliskiren hemifumarate, amlodipine besylate, and hydrochlorothiazide)
Tekturna (aliskiren hemifumarate)
Tekturna HCT (aliskiren hemifumarate and hydrochlorothiazide)
Tekamlo (aliskiren hemifumarate and amlodipine besylate)
Valturna (aliskiren hemifumarate and valsartan).
