Tekturna HCT

1 What is Tekturna HCT?

Brand: Tekturna HCT

Generic: Aliskiren and Hydrochlorothiazide

Tekturna HCT is used to treat hypertension (high blood pressure). Hypertension adds to the workload of the heart and arteries.

If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the heart, brain, and kidneys, resulting in a stroke, heart failure or kidney failure. Lowering blood pressure will reduce the risk of strokes and heart attacks.

Aliskiren is a renin inhibitor. It works by blocking an enzyme in the body that is necessary to produce a substance that causes blood vessels to tighten. As a result, the blood vessels relax and this decreases blood pressure. When blood pressure is lowered, the amount of blood and oxygen that go to the heart is increased.

Hydrochlorothiazide is a thiazide diuretic (water pill). It reduces the amount of water in the body by increasing the flow or urine, which helps lower the blood pressure.

This medication is only available with your doctor’s prescription. This medication is available in the following forms:

  • Tablet
