Adenosine solution for infusion contains a medicine called adenosine. This belongs to a group of medicines called ‘coronary vasodilatators’.
This medicine is for diagnostic use only.
Adenosine solution for infusion is used before a test called “myocardial perfusion imaging” to look at your heart. During his test you are given a medicine called a radiopharmaceutical”. Adenosine solution for infusion works by opening up your heart’s blood vessels and allowing blood to flow more freely. This allows the “radiopharmaceutical” medicine to get into your heart. The doctor can see your heart and assess your heart condition. This procedure is used if you are unable to exercise due to disability or if an exercise stress test is not possible.
Q Do not use Adenosine solution for infusion if:
x You are allergic (hypersensitive) to adenosine or any of the other ingredients of Adenosine solution for infusion (listed in section 6 below). Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue x You have very low blood pressure (severe hypotension) x You have unstable angina which is not controlled by treatment with medicine x You have asthma or any other severe breathing problem x You are taking a medicine called dipyridamole used to thin the blood. x You have heart failure where your heart is not pumping out enough blood x You have problems with your heart rhythm and do not have a pace maker (second or third degree AtrioVentricular block, sick sinus syndrome) x You have been told you have ‘Long QT syndrome’. This is a rare heart problem that can lead to a fast heart-beat and fainting

Separate venous sites for Adenosine Solution for Infusion and radionuclide administration are recommended to avoid an adenosine bolus effect.

3. To avoid an adenosine bolus effect, blood pressure should be measured in the arm opposite to the Adenosine Solution for Infusion.
