Summary for the public


What is Rapiscan?

Rapiscan is a solution for injection that contains the active substance regadenoson.


What is Rapiscan used for?

Rapiscan is for diagnostic use only. It is used in a type of heart scan called ‘radionuclide myocardial perfusion imaging’ to see the blood flow in the heart muscle.

Before this type of scan, the patient’s heart is usually put under stress by exercise such as walking or running on a treadmill to help dilate (widen) the blood vessels in the heart and increase the blood flow to the heart muscle. Rapiscan is used as a ‘stress agent’ that has a similar effect on the heart as exercise. It is used in adult patients (aged 18 years or over) who are unable to exercise enough for a stress test.

The medicine can only be obtained with a prescription.


How is Rapiscan used?

Rapiscan must only be used in a hospital that has equipment for resuscitation and monitoring the patient.
It is given as a 10-second injection of 400 micrograms into a vein immediately followed by an injection of sodium chloride (salt) solution. The patient then undergoes the procedures for radionuclide myocardial perfusion imaging, starting with an injection of a radioactive substance 10 to 20 seconds after the sodium chloride injection. Because Rapiscan causes a rapid increase in heart rate and a fall in blood pressure, patients should remain sitting or lying down and be monitored frequently until the effects of the medicine have worn off.

Rapiscan should only be used once within any 24-hour period. Patients must not take any medicines or products that contain methylxanthines (such as caffeine or theophylline) for at least 12 hours before receiving Rapiscan. They should also stop receiving dipyridamole (a medicine used to prevent blood clots) for at least two days before receiving Rapiscan. For further information on the use of Rapiscan, see the summary of product characteristics (also part of the EPAR).


How does Rapiscan work?

The active substance in Rapiscan, regadenoson, is an A2A adenosine receptor agonist. It works by attaching to A2A adenosine receptors in the walls of the blood vessels in the heart, causing the blood vessels to widen and increasing blood flow into the heart muscle. This enables the blood flow in the heart to be seen more easily during myocardial perfusion imaging.


How has Rapiscan been studied?

The effects of Rapiscan were first tested in experimental models before being studied in humans.

In two main studies, around 2,000 adult patients first had a myocardial perfusion imaging scan performed using adenosine (another medicine used as a stress agent) followed by a second scan with either adenosine or Rapiscan. The main measure of effectiveness was based on the similarity between the results of the scans with Rapiscan and adenosine.


What benefit has Rapiscan shown during the studies?

The results of scans using Rapiscan and adenosine were comparable. The ‘agreement rates’ between the first and second scans were similar regardless of which of the two medicines were used for the second scan.


What is the risk associated with Rapiscan?

The most common side effects with Rapiscan (seen in more than 1 patient in 10) are headache, dizziness, ST segment changes (an abnormal reading on the electrocardiogram or ECG), flushing (reddening of the skin), dyspnoea (difficulty breathing), gastrointestinal (stomach and gut) discomfort and chest pain. For the full list of all side effects reported with Rapiscan, see the package leaflet.

Rapiscan should not be used in people who may be hypersensitive (allergic) to regadenoson or any of the other ingredients. It must not be used in patients with slow heart rate unless they have a pacemaker, unstable angina (a type of chest pain that changes in severity) that has not been controlled with treatment, severe hypotension (low blood pressure) or decompensated heart failure (when the heart does not work as well as it should).


Why has Rapiscan been approved?

The CHMP decided that Rapiscan’s benefits are greater than its risks and recommended that it be given marketing authorisation.

CLINICAL PARTICULARS
4.1 Therapeutic indications
This medicinal product is for diagnostic use only.
Rapiscan is a selective coronary vasodilator for use as a pharmacological stress agent for radionuclide
myocardial perfusion imaging (MPI) in adult patients unable to undergo adequate exercise stress.
4.2 Posology and method of administration
Treatment with Rapiscan is restricted to use in a medical facility where cardiac monitoring and
resuscitation equipment are available.
Posology
The recommended dose of Rapiscan is a single injection of 400 micrograms regadenoson (5 ml) into a
peripheral vein, with no dose adjustment necessary for body weight.
Patients should avoid consumption of any products containing methylxanthines (e.g. caffeine) as well
as any medicinal products containing theophylline for at least 12 hours before Rapiscan administration
(see section 4.5).
When possible, dipyridamole should be withheld for at least two days prior to Rapiscan administration
(see section 4.5).
Aminophylline may be used to attenuate severe and/or persistent adverse reactions to Rapiscan
(see section 4.4).
Rapiscan causes a rapid increase in heart rate (see sections 4.4 and 5.1). Patients should remain sitting
or lying down and be monitored at frequent intervals after the injection until the ECG parameters,
heart rate and blood pressure have returned to pre-dose levels.
Repeated use
This product is to be administered only once within a 24 hour period. Safety and tolerability of
repeated use of this product within 24 hours has not been characterised.
2
Paediatric population
The safety and efficacy of Rapiscan in children below the age of 18 years have not yet been
established.
No data are available.
Elderly
No dose adjustment is necessary (see section 5.2).
Hepatic impairment
No dose adjustment is necessary (see section 5.2).
Renal impairment
No dose adjustment is necessary (see section 5.2).
Method of administration
For intravenous use.
Rapiscan should be administered as a rapid, 10-second injection into a peripheral vein using a
22-gauge or larger catheter or needle.
5 ml of sodium chloride 9 mg/ml (0.9%) solution for injection should be administered
immediately after the injection of Rapiscan.
The radiopharmaceutical for the myocardial perfusion imaging agent should be administered
10-20 seconds after the sodium chloride 9 mg/ml (0.9%) solution for injection. The
radiopharmaceutical may be injected directly into the same catheter as Rapiscan.
4.3 Contraindications
Hypersensitivity to the active substance or to any of the excipients (see section 6.1).
Second or third degree atrioventricular (AV) block or sinus node dysfunction, unless these
patients have a functioning artificial pacemaker.
Unstable angina that has not been stabilised with medical therapy.
Severe hypotension.
Decompensated states of heart failure.
4.4 Special warnings and precautions for use
Rapiscan has the potential to cause serious and life-threatening reactions, including those listed below
(see also section 4.8). Continuous ECG monitoring should be performed and vital signs should be
monitored at frequent intervals until the ECG parameters, heart rate and blood pressure have returned
to pre-dose levels. Rapiscan should be used with caution and should only be administered in a medical
facility with cardiac monitoring and resuscitation equipment. Aminophylline may be administered in
doses ranging from 50 mg to 250 mg by slow intravenous injection (50 mg to 100 mg over
30-60 seconds) to attenuate severe and/or persistent adverse reactions to Rapiscan.
Myocardial ischaemia
Fatal cardiac arrest, life-threatening ventricular arrhythmias, and myocardial infarction may result
from the ischaemia induced by pharmacologic stress agents like regadenoson.
Sinoatrial and atrioventricular nodal block
Adenosine receptor agonists including regadenoson can depress the sinoatrial (SA) and AV nodes and
may cause first, second or third degree AV block, or sinus bradycardia.
Hypotension
Adenosine receptor agonists including regadenoson induce arterial vasodilation and hypotension. The
risk of serious hypotension may be higher in patients with autonomic dysfunction, hypovolemia, left
3
main coronary artery stenosis, stenotic valvular heart disease, pericarditis or pericardial effusions, or
stenotic carotid artery disease with cerebrovascular insufficiency.
Bronchoconstriction
Adenosine receptor agonists may cause bronchoconstriction and respiratory compromise. For patients
with known or suspected bronchoconstrictive disease, chronic obstructive pulmonary disease (COPD)
or asthma, appropriate bronchodilator therapy and resuscitative measures should be available prior to
Rapiscan administration.
Long QT syndrome
Regadenoson stimulates sympathetic output and may increase the risk of ventricular tachyarrhythmias
in patients with a long QT syndrome.
Warnings related to excipients
This medicinal product contains less than 1 mmol sodium (23 mg) per dose. However, the injection of
sodium chloride 9 mg/ml (0.9%) solution given after Rapiscan contains 45 mg of sodium. To be taken
into consideration by patients on a controlled sodium diet.
4.5 Interaction with other medicinal products and other forms of interaction
No studies of interaction with other medicinal products have been performed.
Methylxanthines
Methylxanthines (e.g., caffeine and theophylline) are non-specific adenosine receptor antagonists and
may interfere with the vasodilation activity of regadenoson (see section 5.1). Patients should avoid
consumption of any products containing methylxanthines as well as any medicinal products containing
theophylline for at least 12 hours before Rapiscan administration (see section 4.2).
Aminophylline (100 mg, administered by slow intravenous injection over 60 seconds) injected
1 minute after 400 micrograms regadenoson in subjects undergoing cardiac catheterisation, was shown
to shorten the duration of the coronary blood flow response to regadenoson as measured by pulsed-
wave Doppler ultrasonography. Aminophylline has been used to attenuate adverse reactions to
Rapiscan (see section 4.4).
Dipyridamole
Dipyridamole increases blood adenosine levels and the response to regadenoson may be altered when
blood adenosine levels are increased. When possible, dipyridamole should be withheld for at least two
days prior to Rapiscan administration (see section 4.2).
Cardioactive medicinal products
In clinical studies, Rapiscan was administered to patients taking other cardioactive medicinal products
(i.e., β-blockers, calcium channel blockers, ACE inhibitors, nitrates, cardiac glycosides, and
angiotensin receptor blockers) without apparent effects on the safety or efficacy profile of Rapiscan.
Other interactions
Regadenoson does not inhibit the metabolism of substrates for CYP1A2, CYP2C8, CYP2C9,
CYP2C19, CYP2D6, or CYP3A4 in human liver microsomes, indicating that it is unlikely to alter the
pharmacokinetics of medicinal products metabolised by these cytochrome P450 enzymes.
4.6 Fertility, pregnancy and lactation
Pregnancy
There are no adequate data from the use of Rapiscan in pregnant women. Animal studies on pre- and
post-natal development have not been conducted. Fetotoxicity, but not teratogenicity, was noted in
embryo-fetal development studies (see section 5.3). The potential risk for humans is unknown.
Rapiscan should not be used during pregnancy unless clearly necessary.
4
Breast-feeding
It is unknown whether regadenoson is excreted in human breast milk. The excretion of regadenoson in
milk has not been studied in animals. A decision should be made whether to discontinue breast-
feeding or to abstain from Rapiscan administration taking into account the benefit of breast-feeding for
the child and the benefit of therapy for the woman. If Rapiscan is administered, the woman should not
breast-feed for at least 10 hours (that is, at least 5 times the plasma elimination half-life) following
Rapiscan administration.
Fertility
Fertility studies with Rapiscan have not been performed (see section 5.3).
4.7 Effects on ability to drive and use machines
No studies on the effects of Rapiscan on the ability to drive and use machines have been performed.
Rapiscan administration may result in adverse reactions such as dizziness, headache, and dyspnoea
(see section 4.8) soon after administration. However, most adverse reactions are mild and transient,
resolving within 30 minutes after receiving Rapiscan. Therefore, Rapiscan would be expected to have
no or negligible influence on the ability to drive or operate machinery once treatment has been
completed and these reactions have resolved. The physician is advised to provide a recommendation
for the individual patient.
4.8 Undesirable effects
Summary of the safety profile
Adverse reactions in most patients receiving Rapiscan in clinical trials were mild, transient (usually
resolving within 30 minutes after receiving Rapiscan), and required no medical intervention. Adverse
reactions occurred in approximately 80% of patients. The most common adverse reactions reported
during clinical development in a total of 1,651 patients/subjects were: dyspnoea (29%), headache
(27%), flushing (23%), chest pain (19%), electrocardiogram ST segment changes (18%),
gastrointestinal discomfort (15%) and dizziness (11%).
Rapiscan may cause myocardial ischaemia (potentially associated with fatal cardiac arrest,
life-threatening ventricular arrhythmias, and myocardial infarction), hypotension leading to syncope
and transient ischaemic attacks, and SA/AV node block leading to first, second or third degree
AV block, or sinus bradycardia requiring intervention (see section 4.4). Aminophylline may be used to
attenuate severe or persistent adverse reactions to Rapiscan (see section 4.4).

Description of selected adverse reactions
Fatal cardiac arrest, life-threatening ventricular arrhythmias and myocardial infarction may result from
the ischaemia induced by pharmacologic stress agents. Cardiac resuscitation equipment and trained
staff should be available before administering Rapiscan (see section 4.4).
Adenosine receptor agonists, including Rapiscan, can depress the SA and AV nodes and may cause
first, second or third degree AV block, or sinus bradycardia requiring intervention. In clinical trials
first degree AV block (PR prolongation > 220 msec) developed in 3% of patients within 2 hours of
Rapiscan administration; transient second degree AV block with one dropped beat was observed in
one patient receiving Rapiscan. In postmarketing experience, third degree heart block and asystole
have been reported within minutes of Rapiscan administration.
Adenosine receptor agonists, including Rapiscan induce arterial vasodilation and hypotension. In
clinical trials, decreased systolic blood pressure (> 35 mm Hg) was observed in 7% of patients and
decreased diastolic blood pressure (> 25 mm Hg) was observed in 4% of patients within 45 minutes of
Rapiscan administration. The risk of serious hypotension may be higher in patients with autonomic
dysfunction, hypovolemia, left main coronary artery stenosis, stenotic valvular heart disease,
pericarditis or pericardial effusions, or stenotic carotid artery disease with cerebrovascular
insufficiency. In postmarketing experience, syncope and transient ischaemic attacks have been
reported.
Regadenoson increases sympathetic tone, which causes an increase in heart rate and a shortening of
the QT interval. In a patient with a long QT syndrome, sympathetic stimulation can result in less
shortening of the QT interval than is normal and may even cause a paradoxical increase in the
QT interval. In these patients, the phenomenon of R-on-T syndrome can occur, wherein an extra beat
interrupts the T wave of the previous beat, and this increases the risk of a ventricular tachyarrhythmia.
6
 
Headache was reported by 27% of subjects who received Rapiscan in clinical trials. The headache was
considered severe in 3% of subjects.
Elderly population
Older patients (≥ 75 years of age; n = 321) had a similar adverse reaction profile compared to younger
patients (< 65 years of age; n = 1,016), but had a higher incidence of hypotension (2% versus < 1%).
4.9 Overdose
In a study of healthy volunteers, symptoms of flushing, dizziness and increased heart rate were
assessed as intolerable at regadenoson doses greater than 0.02 mg/kg.
Treatment
Aminophylline may be used to attenuate severe or persistent adverse reactions to Rapiscan (see
section 4.4).
5.
PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Cardiac therapy, other cardiac preparations, ATC code: C01EB21
Mechanism of action
Regadenoson is a low affinity agonist (K i ≈ 1.3 µM) for the A 2A adenosine receptor, with at least
10-fold lower affinity for the A 1 adenosine receptor (K i > 16.5 µM), and very low, if any, affinity for
the A 2B and A 3 adenosine receptors. Activation of the A 2A adenosine receptor produces coronary
vasodilation and increases coronary blood flow (CBF). Despite low affinity for the A 2A adenosine
receptor, regadenoson has high potency for increasing coronary conductance in rat and guinea pig
isolated hearts, with EC 50 values of 6.4 nM and 6.7-18.6 nM, respectively. Regadenoson shows
selectivity (≥ 215-fold) for increasing coronary conductance (A 2A -mediated response) relative to
slowing of cardiac AV nodal conduction (A 1 -mediated response) as measured by AV conduction time
(rat heart) or the S-H interval (guinea pig heart). Regadenoson preferentially increases blood flow in
coronary relative to peripheral (forelimb, brain, pulmonary) arterial vascular beds in the anaesthetised
dog.
Pharmacodynamic effects
Coronary blood flow
Regadenoson causes a rapid increase in CBF which is sustained for a short duration. In patients
undergoing coronary catheterisation, pulsed-wave Doppler ultrasonography was used to measure the
average peak velocity (APV) of CBF before and up to 30 minutes after administration of Rapiscan
(400 micrograms, intravenously). Mean APV increased to greater than twice baseline by 30 seconds
and decreased to less than half of the maximal effect within 10 minutes (see section 5.2).
Myocardial uptake of the radiopharmaceutical is proportional to CBF. Because regadenoson increases
blood flow in normal coronary arteries with little or no increase in stenotic arteries, regadenoson
causes relatively less uptake of the radiopharmaceutical in vascular territories supplied by stenotic
arteries. Myocardial radiopharmaceutical uptake after Rapiscan administration is therefore greater in
areas perfused by normal relative to stenosed arteries.
Haemodynamic effects
The majority of patients experience a rapid increase in heart rate. The greatest mean change from
baseline (21 bpm) occurs approximately 1 minute after administration of Rapiscan. Heart rate returns
to baseline within 10 minutes. Systolic blood pressure and diastolic blood pressure changes were
variable, with the greatest mean change in systolic pressure of −3 mm Hg and in diastolic pressure of
−4 mm Hg approximately 1 minute after Rapiscan administration. An increase in blood pressure has
7
been observed in some patients (maximum systolic blood pressure of 240 mm Hg and maximum
diastolic blood pressure of 138 mm Hg).
Respiratory effects
The A 2B and A 3 adenosine receptors have been implicated in the pathophysiology of
bronchoconstriction in susceptible individuals (i.e., asthmatics). In in vitro studies, regadenoson has
been shown to have little binding affinity for the A 2B and A 3 adenosine receptors. The incidence of
bronchoconstriction (FEV 1 reduction > 15% from baseline) after Rapiscan administration was
assessed in two randomised, controlled clinical studies. In the first study in 49 patients with moderate
to severe COPD, the rate of bronchoconstriction was 12% and 6% following Rapiscan and placebo
dosing, respectively (p = 0.31). In the second study in 48 patients with mild to moderate asthma who
had previously been shown to have bronchoconstrictive reactions to adenosine monophosphate, the
rate of bronchoconstriction was the same (4%) following both Rapiscan and placebo dosing. In both
studies, dyspnoea was reported as an adverse reaction following Rapiscan dosing (61% for patients
with COPD; 34% for patients with asthma) while no subjects experienced dyspnoea following placebo
dosing. Dyspnoea did not correlate with a decrease in FEV 1 .
Clinical efficacy
Clinical studies have demonstrated the efficacy and safety of Rapiscan in patients indicated for
pharmacologic stress radionuclide MPI.
The efficacy and safety of Rapiscan were determined relative to adenosine in two randomised, double-
blind studies (ADVANCE MPI 1 and ADVANCE MPI 2) in 2,015 patients with known or suspected
coronary artery disease who were referred for a clinically-indicated pharmacologic stress MPI. A total
of 1,871 of these patients had images considered valid for the primary efficacy evaluation, including
1,294 (69%) men and 577 (31%) women with a median age of 66 years (range 26-93 years of age).
Each patient received an initial stress scan using adenosine (6-minute infusion using a dose of
0.14 mg/kg/min, without exercise) with a radionuclide gated SPECT (single photon emission
computed tomography) imaging protocol. After the initial scan, patients were randomised to either
Rapiscan or adenosine, and received a second stress scan with the same radionuclide imaging protocol
as that used for the initial scan. The median time between scans was 7 days (range of 1-104 days).
The most common cardiovascular histories included hypertension (81%), coronary artery bypass graft
(CABG), percutaneous transluminal coronary angioplasty (PTCA) or stenting (51%), angina (63%),
and history of myocardial infarction (41%) or arrhythmia (33%); other medical history included
diabetes (32%) and COPD (5%). Patients with a recent history of serious uncontrolled ventricular
arrhythmia, myocardial infarction, or unstable angina, a history of greater than first degree AV block,
or with symptomatic bradycardia, sick sinus syndrome, or a heart transplant were excluded. A number
of patients took cardioactive medicinal products on the day of the scan, including β-blockers (18%),
calcium channel blockers (9%), and nitrates (6%).
Image agreement
Comparison of the images obtained with Rapiscan to those obtained with adenosine was performed as
follows. Using the 17-segment model, the number of segments showing a reversible perfusion defect
was calculated for the initial adenosine study and for the randomised study obtained using Rapiscan or
adenosine. In the pooled study population, 68% of patients had 0-1 segments showing reversible
defects on the initial scan, 24% had 2-4 segments, and 9% had ≥ 5 segments. The agreement rate for
the image obtained with Rapiscan or adenosine relative to the initial adenosine image was calculated
by determining how frequently the patients assigned to each initial adenosine category (0-1, 2-4, 5-17
reversible segments) were placed in the same category with the randomised scan. The agreement rates
for Rapiscan and adenosine were calculated as the average of the agreement rates across the three
categories determined by the initial scan. The ADVANCE MPI 1 and ADVANCE MPI 2 studies,
individually and combined, demonstrated that Rapiscan is similar to adenosine in assessing the extent
of reversible perfusion abnormalities:

0.61, respectively; as were the weighted kappas of two consecutive adenosine scans, 0.50 and 0.55,
respectively.
Safety and tolerability testing
In ADVANCE MPI 1 and ADVANCE MPI 2, the following pre-specified safety and tolerability
endpoints comparing Rapiscan to adenosine achieved statistical significance: (1) a summed score of
both the presence and severity of the symptom groups of flushing, chest pain, and dyspnoea was lower
with Rapiscan (0.9 ± 0.03) than with adenosine (1.3 ± 0.05); and (2) the symptom groups of flushing
(21% vs 32%), chest pain (28% vs 40%), and ‘throat, neck or jaw pain’ (7% vs 13%) were less
frequent with Rapiscan; the incidence of headache (25% vs 16%) was more frequent with Rapiscan.
Paediatric population
The European Medicines Agency has deferred the obligation to submit the results of studies with
Rapiscan in one or more subsets of the paediatric population with myocardial perfusion disturbances
(see section 4.2 for information on paediatric use).
5.2 Pharmacokinetic properties
Absorption
Rapiscan is administered by intravenous injection. The regadenoson plasma concentration-time profile
in healthy volunteers is multi-exponential in nature and best characterised by 3-compartment model.
The maximal plasma concentration of regadenoson is achieved within 1 to 4 minutes after injection of
Rapiscan and parallels the onset of the pharmacodynamic response (see section 5.1). The half-life of
this initial phase is approximately 2 to 4 minutes. An intermediate phase follows, with a half-life on
average of 30 minutes coinciding with loss of the pharmacodynamic effect. The terminal phase
consists of a decline in plasma concentration with a half-life of approximately 2 hours. Within the
dose range of 0.003-0.02 mg/kg (or approximately 0.18-1.2 mg) in healthy subjects, clearance,
terminal half-life or volume of distribution do not appear dependent upon the dose.
Distribution
Regadenoson is moderately bound to human plasma proteins (25-30%).
Biotransformation
The metabolism of regadenoson is unknown in humans. Incubation with rat, dog, and human liver
microsomes as well as human hepatocytes produced no detectable metabolites of regadenoson.
Following intravenous administration of 14 C-radiolabeled regadenoson to rats and dogs, most
radioactivity (85-96%) was excreted in the form of unchanged regadenoson. These findings indicate
that metabolism of regadenoson does not play a major role in the elimination of regadenoson.
Elimination
In healthy volunteers, 57% of the regadenoson dose is excreted unchanged in the urine
(range 19-77%), with an average plasma renal clearance around 450 ml/min, i.e., in excess of the
glomerular filtration rate. This indicates that renal tubular secretion plays a role in regadenoson
elimination.
9
 
Special populations
A population pharmacokinetic analysis including data from subjects and patients demonstrated that
regadenoson clearance decreases in parallel with a reduction in creatinine clearance (CLcr) and
increases with increased body weight. Age, gender, and race have minimal effects on the
pharmacokinetics of regadenoson.
Renal impairment
The disposition of regadenoson was studied in 18 subjects with various degrees of renal function and
in 6 healthy subjects. With increasing renal impairment, from mild (CLcr 50 to < 80 ml/min) to
moderate (CLcr 30 to < 50 ml/min) to severe renal impairment (CLcr < 30 ml/min), the fraction of
regadenoson excreted unchanged in urine and the renal clearance decreased, resulting in increased
elimination half-lives and AUC values compared to healthy subjects (CLcr ≥80 ml/min). However, the
maximum observed plasma concentrations as well as volumes of distribution estimates were similar
across the groups. The plasma concentration-time profiles were not significantly altered in the early
stages after dosing when most pharmacologic effects are observed. No dose adjustment is needed in
patients with renal impairment.
The pharmacokinetics of regadenoson in patients on dialysis has not been assessed.
Hepatic impairment
Greater than 55% of the regadenoson dose is excreted unchanged in the urine and factors that decrease
clearance do not affect the plasma concentration in the early stages after dosing when clinically
meaningful pharmacologic effects are observed. The pharmacokinetic parameters of regadenoson have
not been specifically evaluated in those with varying degrees of hepatic impairment. However,
post-hoc analysis of data from the two Phase 3 clinical trials showed that the pharmacokinetics of
regadenoson were not affected in a small subset of patients with laboratory values suggestive of
impaired hepatic function (2.5-fold transaminase elevation or 1.5-fold elevation of serum bilirubin or
prothrombin time). No dose adjustment is needed in patients with hepatic impairment.
Elderly patients
Based on a population pharmacokinetic analysis, age has a minor influence on the pharmacokinetics of
regadenoson. No dose adjustment is needed in elderly patients.
Paediatric population
The pharmacokinetic parameters of regadenoson have not yet been studied in the paediatric population
(< 18 years).
5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of safety
pharmacology, single and repeated dose toxicity, genotoxicity, or embryo-fetal development. Signs of
maternal and fetal toxicity were seen in rats and rabbits (reduced fetal weights, delays in ossification
[rats], reduced litter size and number of live fetuses [rabbits]), but not teratogenicity. Fetal toxicity was
noted following repeated daily administration of regadenoson, but at doses sufficiently in excess of the
recommended human dose. Fertility and pre- and post-natal studies have not been conducted.

Further information
1.
WHAT RAPISCAN IS AND WHAT IT IS USED FOR
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’.
The scan 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.
2.
BEFORE YOU ARE GIVEN RAPISCAN
Your doctor will not give you Rapiscan
-
if you are allergic (hypersensitive) to regadenoson or any of the other ingredients of Rapiscan
listed in section 6 of this leaflet.
-
if you have slow heart rate (high degree heart block or sinus node disease) , and don’t have a
pacemaker fitted.
-
if you have chest pain that occurs unpredictably (unstable angina) and that has not improved
after treatment.
-
if you have low blood pressure (hypotension) .
-
if you have heart failure.
Take special care with Rapiscan
Your doctor needs to know before you are given Rapiscan:
-
if you have had a recent serious heart problem (for example a heart attack or abnormal heart
rhythms).
-
if you have episodes of heart block (which can slow the heart down) or a very slow heart rate.
20
-
Keep this leaflet. You may need to read it again.
2.
Before you are given Rapiscan
-
if you have a heart rhythm disorder called long QT syndrome.
- if you have any heart or blood vessel condition, particularly one that gets worse when your
blood pressure decreases. These include low blood volume (caused, for example, by severe
diarrhoea or dehydration or taking water pills), inflammation around the heart (pericarditis)
and some forms of heart valve or artery disease (for example, aortic or mitral stenosis).
- if you have asthma or lung disease.
If any of these apply to you, tell your doctor before the injection.
Children
Rapiscan should not be used in children below the age of 18 years.
Using other medicines
Please tell your doctor if you are taking or have recently taken any other medicines including
medicines obtained without prescription.
Particular care should be taken with the following medicines:
-
theophylline, a medicine used to treat asthma and other lung diseases, must not be used for at
least 12 hours before you are given Rapiscan because it can block the effect of Rapiscan.
-
dipyridamole, a medicine used to prevent blood clots, must not be used for at least two days
before you are given Rapiscan because it can change the effect of Rapiscan.
Using Rapiscan with food and drink
Do not eat food or have drinks containing caffeine (for example, tea, coffee, cocoa, cola or chocolate)
for at least 12 hours before you are given Rapiscan. This is because caffeine can interfere with the
effect of Rapiscan.
Pregnancy and breast-feeding
Before you are given Rapiscan, tell your doctor:
-
if you are pregnant or think you are pregnant. There is no adequate information on the use of
Rapiscan in pregnant women. Harmful effects have been seen in animal studies but it is not
known if there is a risk to humans. Your doctor will only give you Rapiscan if it is clearly
necessary.
-
if you are breast-feeding. It is not known whether Rapiscan can pass into breast milk and will
only be given to you if your doctor thinks it is necessary. You should avoid breast-feeding for at
least 10 hours after you are given Rapiscan.
Ask your doctor for advice before using any medicine.
Driving and using machines
Rapiscan may make you feel dizzy. It may cause other symptoms (headache or shortness of breath)
that could affect your ability to drive or use machinery. These effects usually do not last longer than
30 minutes. Do not drive or operate machinery until these effects have improved.
Important information about some of the ingredients of Rapiscan
This medicine contains less than 1 mmol sodium (23 mg) per dose. After you have been given
Rapiscan, you will be given an injection of sodium chloride 9 mg/ml (0.9%) solution which contains
45 mg of sodium. To be taken into consideration if you are on a controlled sodium diet.
3.
HOW RAPISCAN IS GIVEN
Rapiscan is injected by a healthcare professional (a doctor, nurse or medical technician) in a
medical facility where your heart and blood pressure can be monitored. It is injected directly into a
vein, as a single dose of 400 micrograms in a 5 ml solution – the injection will take about 10 seconds
to complete. The dose injected does not depend on your weight.
You will also be given an injection of sodium chloride 9 mg/ml (0.9%) solution (5 ml), and an
injection of a small amount of a radioactive substance (radiopharmaceutical).
21
When you are given Rapiscan, your heart rate will increase quickly. Your heart rate and blood
pressure will be monitored.
After the Rapiscan injection, you will need to sit or lie down until your heart rate and blood pressure
return to your normal levels. The doctor, nurse or medical technician will let you know when you can
stand up.
A scan of your heart will be made after enough time has passed to allow the radiopharmaceutical to
reach the heart muscle.
If you are given more Rapiscan than you should
Some people have had flushing, dizziness and increased heart rate when they have been given too
much Rapiscan. If your doctor thinks that you are having severe side effects, or the effects of Rapiscan
are lasting too long, they may give you an injection of a medicine called aminophylline that reduces
these effects.
4.
POSSIBLE SIDE EFFECTS
Like all medicines, Rapiscan can cause side effects, although not everybody gets them.
The side effects are usually mild. They normally start soon after the Rapiscan injection and are
usually over within 30 minutes. They don’t usually need any treatment.
More serious side effects include:
-
sudden stopping of the heart or damage to the heart, heart block (a disorder of the heart’s
electrical signal, where the signal cannot pass from the upper to the lower chambers), rapid
heart beat
-
low blood pressure which may result in fainting or mini strokes (including weakness of the face
or an inability to speak)
Tell your doctor straight away if you think you are having severe side effects. Your doctor may then
give you an injection of a medicine called aminophylline that reduces these effects.
