| Canada: Rasilez (aliskiren): Health Canada reviewing safety of blood-pressure drug (English Only) |
| |
In light of the recent company decision (Novartis press release) to stop a multi-national clinical trial known as the ALTITUDE study, Health Canada is informing Canadians that it is reviewing the safety of the prescription blood-pressure drug Rasilez (the brand name for aliskiren). The ALTITUDE study (ALiskiren Trial In Type 2 diabetes Using cardio-renal Disease Endpoints) was investigating if Rasilez could reduce the risk of cardiovascular (heart-related) and renal (kidney) events when added to conventional therapies in patients with diabetes and kidney impairment. In the study, Rasilez was given in addition to other blood-pressure lowering drugs. Novartis terminated the study after interim data suggested that Rasilez was unlikely to benefit these patients participating in the clinical trial and could potentially lead to harm. Specifically, when used in combination with other blood pressure -lowering drugs known as angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), Rasilez was associated with an increased risk of non-fatal stroke, kidney complications, hyperkalemia (high levels of potassium in the blood) and low blood pressure. Rasilez is currently authorized in Canada for use either alone or in combination with other drugs including ACE-inhibitors and ARBs to control high blood pressure.
