What is it and how is it used?
Rapiscan contains the active substance, regadenoson. This belongs to a group of medicines called ?coronary vasodilators?. It makes the heart arteries expand and heart rate increase. This makes more blood flow to the muscles of the heart.
This medicine is for diagnostic use only.
Rapiscan is used in a type of heart scan in adults called ?myocardial perfusion imaging?.
Thescan uses a radioactive substance called a ?radiopharmaceutical? to create images. These images show how well blood flows to the muscles of the heart. Usually, exercise on a treadmill is used to put the heart under stress before a scan. During the exercise, a small amount of radiopharmaceutical is injected into the body, often into a vein in the hand. Images are then taken of the heart. The doctor can then see if the heart muscles are getting enough blood flow when it is under stress.
Rapiscan is used instead if someone is not able to exercise enough for the scan.
