How it works

The three medicines lower blood pressure in different ways:

• Telmisartan blocks the action of angiotensin II, a hormone that narrows blood vessels. This relaxes and widens the blood vessels.
• Amlodipine relaxes the muscles in the blood vessel walls, allowing blood to flow more easily.
• Hydrochlorothiazide helps the kidneys remove excess salt and water through urine, reducing the volume of fluid in the bloodstream.
