Aliskiren (Oral)

Aliskiren belongs to a class of drugs known as renin inhibitors; it works by obstructing enzymes responsible for causing blood vessels to constrict.


Aliskiren is administered alone or in combination with other drugs to treat hypertension (high blood pressure). High blood pressure is known to overburden the heart and arteries. If high blood pressure persists for too long, then the heart and arteries may get damaged and stop functioning normally. This damages the major blood vessels leading to the heart, brain and kidney thus causing stroke, heart failure and in some cases kidney failure. Lowering blood pressure is the solution to reducing the risk of heart failure or stroke.

Aliskiren is essentially a renin inhibitor. It simply works by obstructing the enzymes that cause blood vessels to constrict or tighten. When this medication is taken, blood vessels relax and blood pressure is lowered. The quantity of blood and oxygen flowing to the heart increases when blood pressure is decreased. This medicine can also be used treat other conditions not mentioned here.

In addition to treating high blood pressure with this medication, doctors recommend that you make serious lifestyle changes in order to effectively manage your blood pressure. These adjustments include eating healthy food that's low in fat and salt, exercising daily for at least 30 minutes, not smoking tobacco and using alcoholic drinks moderately. This medication can only be prescribed by a doctor.
