Description
Felodipine is an example of a calcium channel blocker. It works by relaxing and widening the blood vessels which transport blood around the body:
- Felodipine blocks the calcium which enters the cells (the building blocks of the body) that make up the muscles in the heart and blood vessels.
- Calcium is vital for muscles to contract so if it is blocked the muscles are automatically relaxed.
- The relaxing of these muscles makes it easier for the heart to pump blood around the body and so blood pressure is lowered.
