1.    WhatAdenosine is and what it is used for

Adenosine contains a medicine called adenosine. This belongs to a group of medicines called ‘coronary vasodilatators'.

This medicine is for diagnostic use only.

Adenosine is used before a test called "myocardial perfusion imaging” to look at your heart. During this test you are given a medicine called a "radiopharmaceutical”.

Adenosine 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 not capable of exercise or if an exercise stress test is not possible.

2.    Before you are given Adenosine

Do not have this medicine and tell your doctor if:

•    You are allergic (hypersensitive) to adenosine or any of the otheringredients ofAdenosine (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.

•    You have very low blood pressure (severe hypotension).

•    You have unstable angina which is not controlled by treatment with medicine.

•    You have asthma or any other severe breathing problem.

•    You are taking a medicine called dipyridamole used to thin the blood.

•    You have a type of heart failure where your heart is not pumping out enough blood.

•    You have problems with your heart rhythm and do not have a pace maker (second or third degree Atrioventricular block, sick sinus syndrome).

•    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.

Do not have this medicine if any of the above apply to you. If you are not sure, talk to your doctor or nurse before you are givenAdenosine.

Warnings and precautions

Talk to your doctor or nurse before you have Adenosine if:

•    You have low blood volume (hypovolaemia) that is not adequately corrected by treatment with medicines.

•    You have problems with a part of your nervous system called the ‘autonomic nervous system'.

•    You have narrowing of the main arteries in the neck (carotid artery). This means that not enough blood is getting to the brain (cerebrovascular insufficiency).

•    You haveorhaveeverhadfitsorconvulsions.

•    You have difficulty in breathing (bronchospasm).

•    You have heart disease due to narrowing of your heart valves (stenotic valvular heart disease).

•    You have inflammation of the membrane surrounding your heart (pericarditis) or a build-up of fluid around your heart (pericardial effusion).

•    You have a left-right shunt in your heart. This will mean blood goes directly from the left side of your heart to the right side.

•    You have narrowing of the left main artery supplying blood to your heart (left main coronary stenosis).

•    You have had a recent heart attack, severe heart failure or you have had a heart transplant in the last year.

•    You have an unusual heart rhythm. For example, your heartbeat is very fast or uneven (atrial fibrillation or atrial flutter) and in particular if you have an ‘accessory conduction pathway'.


The following information is intended for healthcare professionals only:

Posology and Method of Administration

Adenosine 30 mg/10 ml solution for infusion is intended for use in hospitals with monitoring and cardio-respiratory resuscitation equipment available for immediate use if necessary.

It should be administered following the same procedure as for exercise testing where facilities for cardiac monitoring and cardiorespiratory resuscitation are available. During administration of Adenosine 30 mg/10 ml solution for infusion continuous ECG control is necessary as life- threatening arrhythmia might occur. Heart rate and blood pressure should be monitored every minute. Posology Adults:

1.    Adenosine 30 mg/10 ml solution for infusion should be administered undiluted as a continuous peripheral intravenous infusion at a dose of 140 gg/kg/min forsix minutes using an infusion pump. Separate venous sites for Adenosine 30 mg/10 ml solution for infusion and radionuclide administration are recommended to avoid an adenosine bolus effect.

2.    After three minutes ofAdenosine 30 mg/10 ml solution for infusion, the radionuclide is injected to ensure sufficient time for peak coronary blood flow to occur. The optimal vasodilator protocol is achieved with six minutes ofAdenosine 30 mg/10 ml solution for infusion.

3.    To avoid an adenosine bolus effect, blood pressure should be measured in the arm opposite to the Adenosine 30 mg/10 ml solution forinfusion.

You have any minor problem with your heart (first degree Atrioventricular block or bundle branch block). These conditions may be temporarily aggravated when you are given Adenosine.

If you are not sure if any of the above apply to you, talk to your doctorornurse before being givenAdenosine.

Other medicines and Adenosine

Please tell your doctor or nurse if you are taking or have recently taken any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because Adenosine can affect the way some other medicines work. Also some medicines can affect the wayAdenosine works.

In particular, check with your doctor or nurse if you are taking any ofthefollowing:

•    Dipyridamole (medicine used to thin the blood). Make sure your doctor knows you are taking dipyridamole. Your doctor may tell you to stop taking dipyridamole 24 hours before you are given Adenosine or you may be given a much lower dose of Adenosine.

•    Aminophylline, theophylline orotherxanthines (medicines used to help breathing). Yourdoctor may tell you to stop taking it 24 hours before you are givenAdenosine.

Adenosine with food and drink

Food and drinks containing xanthines such as tea, coffee, chocolate and cola should be avoided for at least 12 hours before you are givenAdenosine.

•    You are pregnant, might become pregnant, or think that you may be pregnant. You should not be given Adenosine unless clearly necessary

3. HowAdenosine is given HowAdenosine is given

•    Adenosine is a medicine for use in hospitals.

•    It will be given to you by a doctoror nurse as an injection. The injection will be into one of your veins and be given over a period of time (this is called an intravenous infusion).

•    Yourheartand blood pressure will be closely monitored.

How much Adenosine is given

If you are not sure why you are being given Adenosine or have any questions about how much Adenosine is being given to you, speaktoyourdoctorornurse.

Adults (including the elderly)

•    The dose is calculated according to your weight.

•    The usual dose is 140 micrograms per kilogram of body weight, per minute. This is given over a period of six minutes through an infusion pump (a slow injection into a vein).

•    The dose of Adenosine is not changed if you have liver or kidney problems.

If you have more Adenosine than you should

As this medicine is given to you by a doctor or nurse it is unlikely that you will be given too much. Your doctor will carefully work out howmuchAdenosine you should be given.

If you have more of this medicine than you should, the following effects may happen:

•    Very low blood pressure (severe hypotension).

•    Slow heartbeat (bradycardia).

•    Aheart problem (asystole).

Your doctor will be monitoring your heart throughout the procedure.

As the length of time adenosine stays in the blood is very short, any side effects of too much Adenosine would quickly stop when the infusion is stopped. Sometimes you may need an injection of a
