Special
warnings and special
precautions for use
Special warnings and precautions for use
Warnings
As in the case of all iodinated contrast agents, non-ionic
water soluble tri-iodinated products
may induce mild, severe or fatal intolerance reactions, often
of early onset but sometimes
delayed.
These reactions cannot be predicted but are more frequent
in patients with a history of allergy
(hives, asthma, hay-fever, eczema, various food and drug
allergies) or who have shown
particular sensitivity during a previous examination with an
iodinated contrast medium.
Risk-benefit should be considered when dehydration
exists, especially when associated with
pre-existing renal or hepatic disease, advanced vascular
disease, and diabetes mellitus, in
infants, young children and elderly patients.
Screening for these reactions by means of iodine reaction
tests or any other tests currently
available is not possible.
Precautions for use
During the examination, the following are required:
surveillance by a physician
maintenance of an intravenous access for
emergency treatment in the event of a reaction.
Caution is required in patients presenting with severe liver
or kidney failure.
Water intake need not be restricted. It is advisable to
maintain abundant urine output in subjects
with kidney failure, diabetes mellitus, myeloma or
hyperuricemia and in very young children
and atheromatous subjects.
Premedication is advisable for subjects at a high risk of
4.4.
Special warnings and special precautions for use
There is a risk of allergic reactions regardless of the route of
administration or the dose.
The risk of allergic reactions associated with products administered
locally for opacification of body cavities is not clear-cut:
Administration via certain specific routes (articular, biliary, intrathecal,
intra-uterine, etc.) results in varying degrees of systemic diffusion, i.e.
systemic effects may be observed.
Oral or rectal administration normally results in very limited systemic
diffusion. If the intestinal mucosa is normal, not more than 5% of the
administered dose is found in urine and the rest is eliminated in faeces.
Conversely, absorption is increased if the mucosa is damaged. In the
event of perforation, this absorption is rapid and total with diffusion into the
peritoneal cavity and the product is eliminated in urine. The occurrence of
dose-dependent systemic effects is therefore dependent on the status of
the intestinal mucosa.
However, the allergic immune mechanism is not dose-dependent and
immuno-allergic reactions may occur at any time, regardless of the
administration route.
Thus, in terms of the frequency and intensity of undesirable effects, there is a
difference between:
products administered via the vascular route and certain local routes, and
products administered via the GI tract which are only slightly absorbed
under normal conditions.
4.4.1. General particulars corresponding to all iodinated contrast agents
4.4.1.1 Warnings
In the absence of specific studies, myelography is not an indication for
Xenetix.
All iodinated contrast agents can cause minor or major reactions that can be
life-threatening. They may occur immediately (within 60 minutes) or be
reaction (allergy, history of poor
tolerance to iodinated products).
Given the risk involved, emergency resuscitation equipment
must be available, particularly
when the subject is concomitantly receiving ß-blockers (see
Drug interactions), since adrenaline
and plasma expansion have little effect in such cases.
delayed (up to 7 days). They are often unpredictable.
Because of the risk of major reactions, emergency resuscitation equipment
should be available for immediate use.
Several mechanisms have been evoked to explain the occurrence of these
reactions:
direct toxicity affecting the vascular endothelium and tissue proteins.
pharmacological
action
modifying
concentration
certain
endogenous factors (histamine, complement factors, inflammation
mediators), observed more frequently with hyperosmolar contrast media.
immediate IgE-mediated allergic reactions to the contrast agent Xenetix
(anaphylaxis)
allergic reactions due to a cellular-type mechanism (delayed cutaneous
reactions)
Patients who have already experienced a reaction during administration of an
iodinated contrast agent are at higher risk of experiencing another reaction
following administration of the same or possibly a different iodinated contrast
agent, and are thus considered to be at-risk patients.
Iodinated contrast agents and the thyroid (see also Section 4.4.1.2.5.)
Before administering an iodinated contrast agent, it is important to ensure that
the patient is not scheduled to undergo a scintigraphic examination or
laboratory tests related to the thyroid or to receive radioactive iodine for
therapeutic purposes.
Administration of contrast agents via any route disrupts hormone
concentrations and iodine uptake by the thyroid or by metastases of thyroid
cancer, until urine iodine levels have returned to normal.
Other warnings
Extravasation is an uncommon complication (0.04% to 0.9%) of intravenous
injections of contrast media. More frequent with the high osmolar products,
most of the injuries are minor, however severe injuries such as skin
ulceration, tissue necrosis, and compartment syndrome may occur with any
iodinated contrast medium. The risk and/or severity factors are patient-related
(poor or fragile vascular conditions), and technique-related (use of a power
injector, large volume). It is important to identify these factors, optimise the
injection site and technique accordingly, and monitor the injection prior to,
during and after the injection of Xenetix.
4.4.1.2. Precautions for use
4.4.1.2.1. Intolerance to iodinated contrast agents:
Prior to the examination:
identify at-risk patients by a precise screening of histories.
Corticosteroids and H1-type antihistamines have been suggested as
premedication in patients presenting with the highest risk for intolerance
reactions (history of intolerance to an iodinated contrast agent). However,
they do not prevent the occurrence of serious or fatal anaphylactic shock.
During the procedure, the following measures must be maintained:
medical surveillance
permanent venous access.
After the examination:
After administration of the contrast agent, the patient must be monitored
for at least 30 minutes, since most serious adverse reactions occur within
this time period.
The patient must be informed of the possibility of delayed reactions (for
up to seven days) (see Section 4.8. Undesirable effects)
4.4.1.2.2. Renal insufficiency
Iodinated contrast agents can induce a transient alteration in renal function or
worsen pre-existing renal insufficiency. Preventive measures include:
Identify at-risk patients, i.e. with dehydration or renal insufficiency,
diabetes,
severe heart failure,
monoclonal
gammapathy (multiple
myeloma, Waldenstrom's macroglobulinemia), a history of renal failure
after iodinated contrast agent administration, children under one year of
age and elderly subjects with atheroma.
Hydrate when necessary using a saline solution.
Avoid combinations with nephrotoxic medicines. If this cannot be avoided,
laboratory monitoring of renal function must be intensified. The medicines
concerned include aminoglycosides, organoplatinum compounds, high
doses of methotrexate, pentamidine, foscarnet and certain antiviral
agents [aciclovir, ganciclovir, valaciclovir, adefovir, cidofovir, tenofovir],
vancomycin, amphotericin B, immunosuppressants such as cyclosporine
or tacrolimus, ifosfamide.
Allow at least 48 hours between two radiological examinations with
injection of contrast agents, or postpone any new examination until renal
function returns to baseline.
Prevent lactic acidosis in diabetics treated with metformin, by monitoring
serum creatinine levels. Normal renal function: treatment with metformin
must be suspended before contrast agent injection and for at least 48
hours after or until normal renal function is restored. Abnormal renal
function: metformin is contraindicated. In case of emergency: if the
examination is mandatory, precautions must be taken, i.e. metformin
discontinuation, hydration, monitoring of renal function and checking for
signs of lactic acidosis.
Iodinated contrast agents can be used in haemodialysed patients as the
agents are removed by dialysis. Prior approval should be obtained from the
haemodialysis department.
4.4.1.2.3. Hepatic insufficiency
Particular attention is required when a patient presents with both hepatic and
renal insufficiency since, in this situation, the risk of contrast agent retention is
increased.
Care should be taken in case of renal or hepatic impairment, diabetes or in
patients with sickle cell disease.
Adequate hydration should be ensured in all patients before and after
contrast media administration and particularly in patients with renal
impairment or diabetes where it is important to maintain hydration to minimise
deterioration in renal function.
4.4.1.2.4. Asthma
Stabilisation of asthma is recommended before the injection of an iodinated
contrast agent.
Due to an increased risk of bronchospasm, special caution should be taken in
patients who suffered an asthmatic attack within eight days prior to the
examination.
4.4.1.2.5. Dysthyroidism
After iodinated contrast agent injection, particularly in patients with a goitre or
a history of dysthyroidism, there is a risk either of a flare-up of
hyperthyroidism or development of hypothyroidism. There is also a risk of
hypothyroidism in neonates who have received, or whose mother has
received, an iodinated contrast agent.
4.4.1.2.6. Cardiovascular diseases (see Section 4.8 Undesirable effects)
In patients with cardiovascular disease (such as early or patent heart failure,
coronaropathy, pulmonary hypertension, valvulopathy, cardiac arrhythmias),
the risk of cardiovascular reactions is increased after administration of an
iodinated contrast agent. Intravasal injection of the contrast medium may
cause pulmonary oedema in patients with manifest or incipient heart failure,
whereas administration in pulmonary hypertension and heart valve disorders
may result in marked changes in haemodynamics. The frequency and degree
of severity appear related to the severity of the cardiac disorders. In case of
severe and chronic hypertension, the risk of renal damage due to
administration of the contrast medium and also due to the catheterisation
itself may be increased. Careful weighing up of the risk-benefit ratio is
necessary in these patients.
4.4.1.2.7. Central nervous system disorders
The benefit-to-risk ratio must be evaluated for each case:
due to the risk of aggravation of neurological symptoms in patients with a
transient ischaemic attack, acute cerebral infarct, recent intracranial
haemorrhage, cerebral oedema, or idiopathic or secondary (tumour, scar)
epilepsy.
if the intra-arterial route is used in an alcoholic patient (acute or chronic
alcoholism) and other drug-addicted subject.
4.4.1.2.8. Phaeochromocytoma
Patients with phaeochromocytoma may develop a hypertensive crisis after
intravascular administration of a contrast agent, and must be monitored prior
to the examination.
4.4.1.2.9. Myasthenia.
Administration of a contrast agent may worsen the symptoms of myasthenia
gravis.
4.4.1.2.10. Intensification of side effects
Adverse reactions related to iodinated contrast agent administration may be
intensified in patients showing pronounced agitation, anxiety and pain.
Appropriate management such as sedation may be necessary.
4.4.1.2.11.
Excipients

per 100 mL, i.e. essentially “sodium-free”.
4.5.
Interaction with
other medicinal
products
and
other forms of
interaction
Drug interactions and other forms of
interactions
Combinations requiring special precautions
Diuretics: In the event of dehydration induced by diuretics,
there is an increased risk of acute
kidney failure, in particular when high doses of iodinated
contrast media are administered.
The subject should be rehydrated before the iodinated
contrast medium is administered.
Metformin: Lactic acidosis was induced by functional kidney
failure related to radiological
investigation of a subject with diabetes mellitus.
Metformin treatment must be withdrawn 48 hours before the
examination and only reinstituted
2 days after the examination
Beta-adrenergic blocking agents: Concurrent intravascular
administration with beta-adrenergic
blocking agents may increase the risk of moderate to
severe anaphylactoid reaction; also
hypotensive effects may be exacerbated; discontinuation of
the beta-adrenergic blocking agent
may be advisable before administration of contrast media in
patients with other risk factors.
4.5.
Interaction with other medicinal products and other forms
of interaction
4.5.1. Medicinal products
+ Metformin in diabetics (see Section 4.4 Precautions for use — renal
insufficiency).
+ Radiopharmaceuticals (see Section 4.4 Warnings)
Iodinated contrast agents alter the uptake of radioactive iodine by the thyroid
for several weeks, which may on the one hand result in diminished uptake in
thyroid scintigraphy and on the other hand decrease the efficacy of iodine 131
treatment.
In patients scheduled to undergo renal scintigraphy with injection of a
radiopharmaceutical excreted by the renal tubules, it is preferable to carry out
this examination before injecting the iodinated contrast agent.
+ Beta blockers, vasoactive substances, angiotensin-converting enzyme
inhibitors, angiotensin receptor antagonists.
These medicinal products reduce the efficacy of the cardiovascular
compensation mechanisms that occur in haemodynamic disorders. The
physician must be aware of this before injecting the iodinated contrast agent
and appropriate intensive care equipment must be available.
+ Diuretics
Due to the risk of dehydration provoked by diuretics, rehydration with water
and electrolytes must be carried out prior to the examination in order to limit
the risk of acute renal failure.
+ Interleukin 2
The risk of developing a reaction to the contrast agents is increased if the
patient has recently been treated with interleukin 2 (intravenous route), i.e.
rash or, more rarely, hypotension, oliguria, or even renal failure.
4.5.2. Other forms of interaction
High concentrations of iodinated contrast agents in plasma and urine may
interfere with the in vitro determination of bilirubin, proteins and inorganic
substances (iron, copper, calcium and phosphate). It is recommended that
these determinations should not be carried out within 24 hours following the
examination.
4.6.
Pregnancy
and
lactation
Pregnancy and Lactation
Pregnancy
The safety of iobitridol administration to pregnant women
has not been demonstrated. Animal
studies have shown no evidence of teratogenic effects.
However, all exposure to X-rays should
be avoided during pregnancy. The decision of whether or
not to perform the examination
should be based on careful evaluation of the expected
benefit and potential risk.
Lactation
No clinical studies have been conducted on the secretion of
iobitridol in breast-milk. Animal
studies have shown excretion in breast-milk to be low (3%).
4.6.
Pregnancy and lactation
Embryotoxicity
Animal studies have not shown any teratogenic effects.
In the absence of any teratogenic effects in animal species, no malformative
effect is expected in humans. To date, substances causing malformations in
humans have always proved to be teratogenic in animals during studies
properly conducted in two species.
Foetotoxicity
The transient iodine overload following administration to the mother may
induce foetal dysthyroidism if the examination takes place after more than 14
weeks of amenorrhoea. However, in view of the reversibility of the effect and
expected benefit to the mother, the isolated administration of an iodinated
contrast agent is justifiable if the indication for the radiological examination in
a pregnant woman has been carefully evaluated.
Mutagenicity and fertility
The product was not found to be mutagenic under the test conditions used.
No data on reproductive function are available.
Lactation
Iodinated contrast agents are only excreted in breast milk in very small
amounts. Isolated administration to the mother consequently involves a minor
risk of adverse reactions in the infant. It is advisable to stop breastfeeding for
24 hours after administration of the iodinated contrast agent.
4.8.
Undesirable
Adverse reactions
Benign reactions may occur: feeling of hotness, very rarely
4.8.
Undesirable effects
effects
nausea, vomiting and redness of
the skin. These reactions are transient and devoid of clinical
consequences.
More serious manifestations are possible. Reactions may
occur as an isolated disorder or
combination of disorders: cutaneous, respiratory,
neurosensory, gastrointestinal and
cardiovascular disorders. The latter may consist of
cardiovascular collapse of variable severity.
Exceptionally, shock and/or circulatory
arrest may occur.
During clinical studies on 905 patients, 11% of patients experienced an
adverse reaction related to administration of Xenetix (apart from feeling of
warmth), the most common being pain, injection site pain, bad taste and
nausea.
Undesirable effects related to the use of Xenetix are generally mild to
moderate, and transient.
The adverse reactions most commonly reported during administration of
Xenetix since marketing are feeling of warmth, and pain and oedema at the
injection site.
The hypersensitivity reactions are usually immediate (during the injection or
over the hour following the start of the injection) or sometimes delayed (one
hour to several days after the injection), and then appear in the form of
adverse skin reactions.
Immediate reactions comprise one or several, successive or concomitant
effects, usually including skin reactions, respiratory and/or cardiovascular
disorders, which may be the first signs of shock, which can rarely be fatal.
Severe rhythm disorders including ventricular fibrillation have been very rarely
reported in heart disease patients, in as well as out of a context of
hypersensitivity (see Section 4.4 Precaution for use).
The adverse reactions are listed in the table below by SOC (System Organ
Class) and by frequency with the following guidelines: very common (
1/10),
common (
1/100 to <1/10), uncommon (

Cardiovascular collapse of variable severity may occur immediately with no
warning signs, or may complicate the cardiovascular manifestations
mentioned in the above table.
Abdominal pain and diarrhoea, not reported for Xenetix, are linked mainly to
administration via the oral or rectal route.
Local pain and oedema may occur at the injection site without extravasation
of the injected product and are benign and transient.
During intra-arterial administration, the sensation of pain at the injection site
depends on the osmolality of the product injected.
Paediatric population
The expected nature of the undesirable effects connected with Xenetix is the
same as that of the effects reported in adults. Their frequency cannot be
estimated from the available data.

Overdose
If a very high dose of contrast agent is administered, the water and electrolyte
loss must be compensated by suitable rehydration. Renal function must be
monitored for at least three days. Haemodialysis may be performed if
necessary.

Special warnings and special precautions for use
There is a risk of allergic reactions regardless of the route of administration or the
dose.
The risk of allergic reactions associated with products administered locally for
opacification of body cavities is not clear-cut:
a) Administration via certain specific routes (articular, biliary, intrathecal, intra-uterine,
etc.) results in varying degrees of systemic diffusion, i.e. systemic effects may be
observed.
b) Oral or rectal administration normally results in very limited systemic diffusion. If the
intestinal mucosa is normal, not more than 5% of the administered dose is found in
urine and the rest is eliminated in faeces. Conversely, absorption is increased if the
mucosa is damaged. In the event of perforation, this absorption is rapid and total with
diffusion into the peritoneal cavity and the product is eliminated in urine. The
occurrence of dose-dependent systemic effects is therefore dependent on the status
of the intestinal mucosa.
c) However, the allergic immune mechanism is not dose-dependent and immuno-
allergic reactions may occur at any time, regardless of the administration route.
Thus, in terms of the frequency and intensity of undesirable effects, there is a difference
between:
products administered via the vascular route and certain local routes, and
products administered via the GI tract which are only slightly absorbed under normal
conditions.

severity factors are patient-related (poor or fragile vascular conditions), and technique-
related (use of a power injector, large volume). It is important to identify these factors,
optimise the injection site and technique accordingly, and monitor the injection prior to,
during and after the injection of Xenetix.
4.4.1.2. Precautions for use
4.4.1.2.1. Intolerance to iodinated contrast agents:
Prior to the examination:
identify at-risk patients by a precise screening of histories.
Corticosteroids and H1-type antihistamines have been suggested as premedication in
patients presenting with the highest risk for intolerance reactions (history of intolerance
to an iodinated contrast agent). However, they do not prevent the occurrence of serious
or fatal anaphylactic shock. During the procedure, the following measures must be
maintained:
medical surveillance
permanent venous access.
After the examination:
After administration of the contrast agent, the patient must be monitored for at least
30 minutes, since most serious adverse reactions occur within this time period.
The patient must be informed of the possibility of delayed reactions (for up to seven
days) (see Section 4.8. Undesirable effects)
4.4.1.2.2. Renal insufficiency
Iodinated contrast agents can induce a transient alteration in renal function or worsen
pre-existing renal insufficiency. Preventive measures include:
Identify at-risk patients, i.e. with dehydration or renal insufficiency, diabetes, severe
heart
failure,
monoclonal
gammapathy
(multiple
myeloma,
Waldenstrom's
macroglobulinemia),
history
renal
failure
after

administration, children under one year of age and elderly subjects with atheroma.
Hydrate when necessary using a saline solution.
Avoid combinations with nephrotoxic medicines. If this cannot be avoided, laboratory
monitoring of renal function must be intensified. The medicines concerned include
aminoglycosides,
organoplatinum
compounds,
high
doses
methotrexate,
pentamidine, foscarnet and certain antiviral agents [aciclovir, ganciclovir, valaciclovir,
adefovir, cidofovir, tenofovir], vancomycin, amphotericin B, immunosuppressants
such as cyclosporine or tacrolimus, ifosfamide.
Allow at least 48 hours between two radiological examinations with injection of
contrast agents, or postpone any new examination until renal function returns to
baseline.
Prevent lactic acidosis in diabetics treated with metformin, by monitoring serum

4.4.1.2.3. Hepatic insufficiency
Particular attention is required when a patient presents with both hepatic and renal
insufficiency since, in this situation, the risk of contrast agent retention is increased.
Care should be taken in case of renal or hepatic impairment, diabetes or in patients with
sickle cell disease.
Adequate hydration should be ensured in all patients before and after contrast media
administration and particularly in patients with renal impairment or diabetes where it is
important to maintain hydration to minimise deterioration in renal function.
4.4.1.2.4. Asthma
Stabilisation of asthma is recommended before the injection of an iodinated contrast
agent.
Due to an increased risk of bronchospasm, special caution should be taken in patients
who suffered an asthmatic attack within eight days prior to the examination.
4.4.1.2.5. Dysthyroidism
After iodinated contrast agent injection, particularly in patients with a goitre or a history of
dysthyroidism, there is a risk either of a flare-up of hyperthyroidism or development of
hypothyroidism. There is also a risk of hypothyroidism in neonates who have received,
or whose mother has received, an iodinated contrast agent.

haemodynamics. The frequency and degree of severity appear related to the severity of
the cardiac disorders. In case of severe and chronic hypertension, the risk of renal
damage due to administration of the contrast medium and also due to the catheterisation
itself may be increased. Careful weighing up of the risk-benefit ratio is necessary in
these patients.
4.4.1.2.7. Central nervous system disorders
The benefit-to-risk ratio must be evaluated for each case:
due to the risk of aggravation of neurological symptoms in patients with a transient
ischaemic attack, acute cerebral infarct, recent intracranial haemorrhage, cerebral
oedema, or idiopathic or secondary (tumour, scar) epilepsy.
if the intra-arterial route is used in an alcoholic patient (acute or chronic alcoholism)
and other drug-addicted subject.
4.4.1.2.8. Phaeochromocytoma
Patients with phaeochromocytoma may develop a hypertensive crisis after intravascular
administration of a contrast agent, and must be monitored prior to the examination.
4.4.1.2.9. Myasthenia.
Administration of a contrast agent may worsen the symptoms of myasthenia gravis.
4.4.1.2.10. Intensification of side effects
Adverse reactions related to iodinated contrast agent administration may be intensified
in patients showing pronounced agitation, anxiety and pain. Appropriate management
such as sedation may be necessary.
4.4.1.2.11. Excipients

Interaction with other medicinal products and other forms of interaction
4.5.1. Medicinal products
+ Metformin in diabetics (see Section 4.4 Precautions for use — renal insufficiency).
+ Radiopharmaceuticals (see Section 4.4 Warnings)
Iodinated contrast agents alter the uptake of radioactive iodine by the thyroid for several
weeks, which may on the one hand result in diminished uptake in thyroid scintigraphy
and on the other hand decrease the efficacy of iodine 131 treatment.

+ Diuretics
Due to the risk of dehydration provoked by diuretics, rehydration with water and
electrolytes must be carried out prior to the examination in order to limit the risk of acute
renal failure.
+ Interleukin 2
The risk of developing a reaction to the contrast agents is increased if the patient has
recently been treated with interleukin 2 (intravenous route), i.e. rash or, more rarely,
hypotension, oliguria, or even renal failure.
4.5.2. Other forms of interaction
High concentrations of iodinated contrast agents in plasma and urine may interfere with
the in vitro determination of bilirubin, proteins and inorganic substances (iron, copper,
calcium and phosphate). It is recommended that these determinations should not be
carried out within 24 hours following the examination.
4.6.
Pregnancy and lactation
Embryotoxicity
Animal studies have not shown any teratogenic effects.
In the absence of any teratogenic effects in animal species, no malformative effect is
expected in humans. To date, substances causing malformations in humans have
always proved to be teratogenic in animals during studies properly conducted in two
species.
Foetotoxicity
The transient iodine overload following administration to the mother may induce foetal
dysthyroidism if the examination takes place after more than 14 weeks of amenorrhoea.
However, in view of the reversibility of the effect and expected benefit to the mother, the
isolated administration of an iodinated contrast agent is justifiable if the indication for the
radiological examination in a pregnant woman has been carefully evaluated.
Mutagenicity and fertility
The product was not found to be mutagenic under the test conditions used.
No data on reproductive function are available.
Lactation
Iodinated contrast agents are only excreted in breast milk in very small amounts.
Isolated administration to the mother consequently involves a minor risk of adverse

Undesirable effects
During clinical studies on 905 patients, 11% of patients experienced an adverse reaction
related to administration of Xenetix (apart from feeling of warmth), the most common
being pain, injection site pain, bad taste and nausea.
Undesirable effects related to the use of Xenetix are generally mild to moderate, and
transient.
The adverse reactions most commonly reported during administration of Xenetix since
marketing are feeling of warmth, and pain and oedema at the injection site.
The hypersensitivity reactions are usually immediate (during the injection or over the
hour following the start of the injection) or sometimes delayed (one hour to several days
after the injection), and then appear in the form of adverse skin reactions.
Immediate reactions comprise one or several, successive or concomitant effects, usually
including skin reactions, respiratory and/or cardiovascular disorders, which may be the
first signs of shock, which can rarely be fatal.
Severe rhythm disorders including ventricular fibrillation have been very rarely reported
in heart disease patients, in as well as out of a context of hypersensitivity (see Section
4.4 Precaution for use).
The adverse reactions are listed in the table below by SOC (System Organ Class) and
by frequency with the following guidelines: very common (

Local pain and oedema may occur at the injection site without extravasation of the
injected product and are benign and transient.
During intra-arterial administration, the sensation of pain at the injection site depends on
the osmolality of the product injected.
Paediatric population
The expected nature of the undesirable effects connected with Xenetix is the same as
that of the effects reported in adults. Their frequency cannot be estimated from the
available data.
4.9.
Overdose
If a very high dose of contrast agent is administered, the water and electrolyte loss must
be compensated by suitable rehydration. Renal function must be monitored for at least
three days. Haemodialysis may be performed if necessary.

PHARMACOLOGICAL PROPERTIES
5.1.
Pharmacodynamic properties
IODINATED CONTRAST AGENT
(V: other) ATC code: V08AB11
Xenetix 250 is a urographic and angiographic water-soluble nonionic contrast agent with
an osmolality of 585 mOsm/kg.
Xenetix 300 is a urographic and angiographic water-soluble nonionic contrast agent with
an osmolality of 695 mOsm/kg.
Xenetix 350 is a urographic and angiographic water-soluble nonionic contrast agent with
an osmolality of 915 mOsm/kg.
5.2.
Pharmacokinetic properties
After intravascular injection, iobitridol is distributed in the intravascular system and
interstitial compartment. In humans, the elimination half-life is 1.8 h, the volume of
distribution is 200 mL/kg and the total clearance is 93 mL/min (mean values). Binding to
plasma proteins is negligible (< 2%). It is mainly eliminated via the kidneys (glomerular
filtration without tubular reabsorption or secretion) in unchanged form. The osmotic
diuresis induced by Xenetix is dependent on the osmolality and the volume injected.
In patients with renal insufficiency, elimination occurs mainly via the biliary route. The
substance can be dialysed.
5.3.
Preclinical safety data
Toxicological results for intravenous use show an absence of effects, or effects occurring
under conditions much more extreme than those recommended for clinical
use (dosage, repeated doses). Following the single administration of high doses (9 to 18
gI/kg), Xenetix caused transient signs of hypothermia, respiratory depression
and dose-dependent histological lesions that occurred in the target organs (liver, kidney)
included
