1. Why am I given LIPIODOL ULTRA FLUID?

LIPIODOL ULTRA FLUID contains the active ingredient iodised oil. LIPIODOL ULTRA FLUID is a diagnostic agent; it belongs to the class of iodinated contrast agents used for radiological examination. LIPIODOL ULTRA FLUID is used to enhance the contrast of the images obtained during these radiological examinations, which improves the visualisation and outline of certain body parts. When mixed with certain medicines to treat cancer, LIPIODOL ULTRA FLUID carries and delivers the cancer medicine into the area to be treated.

LIPIODOL ULTRA FLUID is used during radiological examinations and during surgery.

2. What should I know before I am given LIPIODOL ULTRA FLUID?

4 Clinical Particulars

4.1 Therapeutic Indications

In diagnostic radiology.

Hysterosalpingography in women undergoing infertility workup; lymphangiography; urethrography; radiography of the seminal vesicles, vas deferens and epididymis; nasal sinuses (for which purpose dilution to one-half or one-third strength with liquid paraffin or a suitable vegetable oil is generally advised); dacryocystography; sialography and the exploration of sinuses, fistulae, etc.
It has also been used in the form of a 20% emulsion for the X-ray examination of empyema cavities.

In interventional radiology.

As an imaging agent for visualisation and localisation during trans-arterial chemo-embolisation (TACE) of hepatocellular carcinoma (HCC) at intermediate stage in adults (see Section 4.3 Contraindications; Section 4.4 Special Warnings and Precautions for Use).

4.2 Dose and Method of Administration

Lipiodol Ultra Fluid is for administration using glass syringe or other compatible administration system by slow injection or cannulation (see Section 6.2 Incompatibilities).
After the administration of Lipiodol Ultra Fluid, the patient must be kept under observation for at least 30 minutes.

In diagnostic radiology.

Hysterosalpingography. In hysterosalpingography (HSG), inject increments of 2 mL of Lipiodol Ultra Fluid into the endometrial cavity under fluoroscopic control until tubal patency is determined.
The total volume to be injected depends on the volume of the uterine cavity, usually not exceeding 15 mL.
The dose of Lipiodol Ultra Fluid for hysterosalpingography should be kept as low as possible to minimise the potential risk of thyroid dysfunction. Nonetheless, thyroid dysfunction may occur at the lower recommended dose during hysterosalpingography.
Administration is by slow injection into the uterine cervical cannula via a suitable catheter or cannula. Stop the injection if the patient develops excessive discomfort. The examination should be preferably carried out during the follicular phase of the menstrual cycle.
Care is needed to avoid the risk of venous intravasation. The injection must therefore not be made either during the first few days after a menstrual period or in the few days before a menstrual period is due. When the injection is made by means of a cannula, direct trauma to the uterine mucosa must be avoided. Excessive pressure should not be used in making the injection, which should be avoided entirely when the endometrium and the cervix have been recently subjected to surgical trauma.
On account of the disadvantages and potential dangers (very rare instances of oil emboli and iodism) associated with the use of Lipiodol Ultra Fluid in hysterosalpingography, etc., many radiologists prefer to use water soluble contrast agents.
Lymphangiography. Administration is by lymphatic cannulation. The lymph vessels should first be rendered visible with a subcutaneous injection of Patent Blue V. Lipiodol Ultra Fluid is then injected by means of an automatic infusion machine at a rate of 1 mL every ten minutes.
The usual dosage to visualise the lymphatic system of the leg in the adult patient is 8 mL; in the arm, 3 to 4 mL is usually adequate to show the axillary glands. For bilateral examinations a total of 15 mL usually gives adequate filling of inguinal, iliac and para-aortic glands.

Paediatric population.

In children, dosage is reduced according to bodyweight using approximately 0.25 mL/kg.
The procedure is usually carried out under local analgesia. Exposures are made at the end of the infusion; further films are taken 24 and 48 hours later.
The lymph glands retain Lipiodol Ultra Fluid for several weeks or months and changes in their appearance may be followed by serial radiographs for example, after a course of chemo- or radiotherapy.

Elderly.

The product must be administered with caution in patients over 65 years of age presenting with underlying pathologies of the cardiovascular, respiratory or neurological system.
In elderly patients with cardiorespiratory failure scheduled for a lymphography, the dose should be adapted or the examination itself cancelled, since a portion of the product will temporarily embolise the pulmonary capillaries.

In interventional radiology.

Trans-arterial chemo-embolisation (TACE). The dose of Lipiodol Ultra Fluid depends on the extent of the lesion but should usually not exceed a total dose of 15 mL in adults.
Procedures involving the use of Lipiodol Ultra Fluid in HCC patients should be conducted by interventional radiologists with prerequisite training and a thorough knowledge of the procedure to be performed.
The administration is by selective intra-arterial catheterisation of the hepatic artery. The procedure should be performed within a typical interventional radiology setting with the appropriate equipment.
Lipiodol Ultra Fluid for TACE can be mixed with anticancer medications for HCC in accordance with the applicable clinical guidelines.
Instructions and precautions for use of the anticancer medications must be strictly followed.
Instructions for preparation of the mixture of Lipiodol Ultra Fluid with an anticancer medicine:
Prepare two syringes large enough to contain the total volume of mixture. The first syringe contains the anticancer solution, the second syringe contains Lipiodol Ultra Fluid.
Connect the two syringes to a 3-way stopcock.
Perform 15 to 20 back and forth movements between the two syringes to obtain a homogeneous mixture. It is recommended to start by pushing the syringe with the anticancer medicine first.
The mixture is to be prepared at the time of use and must be used promptly after preparation (within 3 hours). If necessary during the interventional radiology procedure, the mixture can be re-homogenised as described above.
When the adequate mixture is obtained, use a 1 to 3 mL syringe to inject in the micro-catheter.
The procedure can be repeated every 4 to 8 weeks according to tumour response and patient conditions.

Paediatric population.

The efficacy and safety of the use of Lipiodol Ultra Fluid for trans-arterial chemo-embolisation of hepatocellular carcinoma have not been established in children.

Elderly.

Lipiodol Ultra Fluid must be administered with caution in patients over 65 years of age with underlying diseases of the cardiovascular, respiratory or nervous systems.
Limiting the injected dose may also help prevent non-targeted pulmonary embolism which might occur in the course of a hepatic chemoembolisation.

Renal impairment.

Lipiodol Ultra Fluid must be administered cautiously in patients with impaired renal function or pre-existing renal failure (see Section 4.4 Special Warnings and Precautions for Use). Dosage adjustment is not recommended for patients with renal impairment.

4.3 Contraindications

Hypersensitivity to Lipiodol Ultra Fluid (ethyl esters of iodised fatty acids of poppy seed oil).
Lipiodol Ultra Fluid is unsuitable for bronchography.
Recent haemorrhage in the region of investigation.
Hysterosalpingography during pregnancy, acute pelvic inflammation, marked cervical erosion, endocervicitis and intrauterine bleeding, within 30 days of curettage or conisation or in patients with known or suspected reproductive tract neoplasia (due to the risk of peritoneal spread of neoplasm).
Iodine idiosyncrasy: it is strongly recommended that the patient be tested for iodine idiosyncrasy before the administration of Lipiodol Ultra Fluid in other than small amounts. Simple and reliable tests can be affected by painting an area of the skin with iodine solution or by giving potassium iodine orally for a few days. Iodism occurs more frequently with Lipiodol Ultra Fluid than with organic salts of iodine.
Documented hyperthyroidism and documented hypothyroidism.
Lipiodol Ultra Fluid must not be administered by systemic intra-arterial (apart for selective catheterisation) or intravenous injection.
To prevent the occurrence of biloma, in the context of TACE procedure, Lipiodol Ultra Fluid must not be administered in liver areas with dilated bile ducts unless drainage has been performed.

4.4 Special Warnings and Precautions for Use

Lipiodol Ultra Fluid must not be administered intravenously, intra-arterially (apart from selective catheterisation) or intrathecally.
There is a risk of hypersensitivity regardless of the dose administered.

Warnings - all indications.

Hypersensitivity.

All iodinated contrast agents can lead to minor or major hypersensitivity reactions, which can be life threatening. These hypersensitivity reactions are of an allergic nature (known as anaphylactic reactions if they are serious) or a non-allergic nature. They can be immediate (occurring within 60 minutes) or delayed (not occurring until up to 7 days later). Anaphylactic reactions are immediate and can be fatal. They are dose-independent, can occur right from the first administration of the product, and are often unforeseeable.
The risk of a major reaction means that the equipment needed for emergency resuscitation must be immediately at hand.
Patients who have already experienced a reaction after a previous administration of Lipiodol Ultra Fluid or who have a history of iodine hypersensitivity are at increased risk of another reaction on re-administration of the product and are thus regarded as at-risk patients (see Section 4.3 Contraindications).
The injection of Lipiodol Ultra Fluid may aggravate symptoms of a pre-existing asthma. In patients with asthma unbalanced by treatment, the decision to use Lipiodol Ultra Fluid requires careful evaluation of the risk/benefit ratio.

Thyroid dysfunction.

Iodinated contrast media can affect thyroid function because of the free iodine content and can cause hypothyroidism, or hyperthyroidism in predisposed patients. Patients at risk are those with latent hyperthyroidism and those presenting with functional thyroid autonomy. Iodism occurs more frequently with Lipiodol Ultra Fluid than with water soluble organic iodine derivatives. Thyroid disorders may be adequately monitored with thyroid function tests after treatment has been initiated.

Embolic and thrombotic complications.

The uncontrolled migration of Lipiodol Ultra Fluid into the arterio-venous system may induce the temporary obliteration of small vessels (oil embolism) in various organs. Evidence of such embolisation is infrequent, usually immediate but can also be delayed, occurring after a few hours or days and is usually transient. Most reported localisations of such an event include pulmonary embolisms, cerebral embolisms (which could lead to cerebral infarction) and skin embolisms (which could lead to skin necrosis). Patients should be warned of the possible signs of embolism and should contact their doctor or hospital if any symptoms emerge.

Specific warning related to lymphography.

Pulmonary embolisation occurs in the majority of patients undergoing lymphography with Lipiodol Ultra Fluid injection, due to a portion of the product temporarily embolising the pulmonary capillaries. The dose should be adapted or the examination cancelled in patients presenting with impaired lung function, cardiorespiratory insufficiency or pre-existing right-side cardiac overload, particularly if the patient is elderly. Lymphography saturates the thyroid with iodine for several months and any thyroid function tests should therefore be conducted prior to the radiological examination.

Specific warnings related to trans-arterial chemo-embolisation.

Trans-arterial chemo-embolisation is not recommended in patients with decompensated liver cirrhosis (Child-Pugh score ≥ 8), advanced liver dysfunction, macroscopic invasion and/or extrahepatic spread of the tumour.
The uncontrolled migration of Lipiodol Ultra Fluid into the arterio-venous system may induce the temporary obliteration of small vessels (oil embolism) in various organs. Evidence of such embolisation is infrequent, usually immediate but can also be delayed occurring after a few hours or days and is usually transient. Most reported localizations of such an event include pulmonary embolisms, cerebral embolisms and skin embolisms (which could lead to skin necrosis). Patients should be warned of the possible signs of embolism and should contact their doctor or hospital if any symptoms emerge.
Hepatic intra-arterial procedures can cause an irreversible liver insufficiency in patients with serious liver malfunction and/or undergoing close multiple sessions. More than 50% liver replacement with tumour, bilirubin level greater than 2 mg/dL, lactate dehydrogenase level greater than 425 mg/dL, aspartate aminotransferase (AST) level greater than 100 units/L and decompensated cirrhosis have been described as associated with increased post-procedural mortality.
Oesophageal varices must be carefully monitored as they can rupture immediately after treatment. If a risk of rupture is demonstrated, endoscope sclerotherapy/ligature should be performed before the trans-arterial chemo-embolisation procedure.
Iodinated contrast agent induced renal insufficiency must be systematically prevented by correct rehydration before and after the procedure.
The risk of superinfection in the treated area is normally prevented by administration of antibiotics.

Specific warnings related to hysterosalpingography.

Intravasation of Lipiodol Ultra Fluid may occur in the course of a hysterosalpingography procedure and may result in serious pulmonary or cerebral embolic complications (see Embolic and thrombotic complications) in the next hours following the procedure. The hysterosalpingography procedure should be immediately interrupted in case of suspected or confirmed intravasation of Lipiodol Ultra Fluid. The patient should be closely monitored for embolic complication in a care setting deemed appropriate by the treating clinician.
When used in hysterosalpingography in patients considered at risk for hypothyroidism, close monitoring of thyroid function and follow-up of hypothyroidism should be monitored closely for several months after the examination to observe potential development of hypothyroidism. The dose of Lipiodol Ultra Fluid should be kept as low as possible to minimise the potential risk of thyroid dysfunction.

Precautions for use.

Hypersensitivity.

Before the examination: identify patients at risk through precise questioning about their history.
Throughout the examination, it is necessary to ensure the following: medical monitoring; maintenance of venous access.
After the examination:
After administration of a contrast agent, the patient must be kept under observation for at least 30 min, as most of the serious adverse reactions occur within this period.
The patient must be warned of the possibility of delayed reactions (occurring up to 7 days after administration) (see Section 4.8 Adverse Effects (Undesirable Effects)).

Thyroid dysfunction.

To prevent any metabolic disorder, possible thyroid risk factors must be determined. If administration of an iodised contrast agent is planned in such patients at risk, thyroid function must be determined before the examination.

Chemoembolisation.

Iodinated contrast agents can induce a transient alteration in renal function or worsening pre-existing renal insufficiency. Preventive measures include:
Identify patients at risk, i.e. patients who are dehydrated or who have renal insufficiency, diabetes, severe heart failure, monoclonal gammopathy (multiple myeloma, Waldenstrom's macroglobulinemia), a history of renal failure after administration of iodinated contrast agents, children under one year of age and elderly patients with atheroma.
Hydrate the patient before and after the examination.
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 ciclosporin or tacrolimus, ifosfamide.
Allow at least 48 hours between two radiological examinations or procedures with iodinated contrast agent, or delay further examinations or procedures until renal function returns to baseline.
Prevent for lactic acidosis in diabetics treated with metformin, by monitoring serum creatinine levels. Normal renal function: discontinue metformin before and for at least 48 hours after contrast agent administration or until renal function returns to baseline. Abnormal renal function: metformin is contraindicated. In case of emergency, if the examination is mandatory, precautions must be taken, i.e. discontinue metformin, hydrate the patient, monitor renal function and test for signs of lactic acidosis.
Cardiovascular and/or pulmonary co-morbidities should be assessed before initiation of a transarterial chemo-embolisation procedure.

Miscellaneous.

The injection of Lipiodol Ultra Fluid into certain fistulae should be conducted with great care in order to avoid penetration of vascular channels and the possibility of oil emboli.
Care should be taken not to inject the product into an area affected by haemorrhage or trauma.
Indications for the use of Lipiodol Ultra Fluid must be carefully assessed in patients with primary lymph oedema, as the oedema can be exacerbated.
Lipiodol Ultra Fluid has been shown to dissolve polystyrene. Disposable syringes made from the latter must not be used. The product should be administered using a glass syringe or other administration system proven to be compatible with it.

Effects on laboratory tests.

As Lipiodol Ultra Fluid remains in the body for several months, the results of thyroid diagnostic results can be incorrect for up to 2 years after lymphography.

Paediatric use.

Infants.

Thyroid function in infants exposed to iodinated contrast media (ICM) should be evaluated and monitored. Decreased levels of thyroxine (T4) and triiodothyronine (T3) and increased level of thyroid stimulating hormone (TSH) were reported after exposure to ICM in infants, especially preterm infants, which remained for up to a few weeks or more than a month. Thyroid function in infants exposed to ICM should therefore be evaluated and monitored until thyroid function is normalised. Some patients were treated for hypothyroidism.

Use in the elderly.

See Section 4.2 Dose and Method of Administration, Elderly.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Interactions with other medicines.

Metformin.

In diabetic patients, intra-arterial administration of Lipiodol Ultra Fluid may cause lactic acidosis induced by diminished renal function. For patients scheduled to undergo embolisation or a trans-arterial chemo-embolisation, metformin must be discontinued 48 hours before the procedure and resumed no earlier than two days after the procedure.

Combinations requiring caution.

Beta-blockers, vasoactive substances, angiotensin converting enzyme inhibitors, angiotensin receptor blockers.

These medicines reduce the effectiveness of the cardiovascular mechanisms that compensate for blood pressure disturbances. The doctor should be informed about these prior to the administration of Lipiodol Ultra Fluid and have resuscitation equipment at hand.

Interleukin II (IV).

There is an increased risk of reaction to contrast agent in the event of recent interleukin II administration (IV route): skin rash or more rarely hypotension, oliguria or even renal failure.

Diuretics.

There is an increased risk of acute renal failure with diuretics as these may cause dehydration, particularly when high doses of iodinated contrast agents are used.
Precautions for use: rehydration before intra-arterial administration of Lipiodol Ultra Fluid for embolisation or chemoembolisation.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

In women who underwent hysterosalpingography with Lipiodol Ultra Fluid for infertility workup, a significantly higher rate of pregnancy has been observed, compared to women who did not undergo any hysterosalpingography or who underwent hysterosalpingography with water-soluble iodinated contrast agents (see Section 5.1 Pharmacodynamic Properties).
No effects on fertility were observed in female rats treated with a single intra-uterine dose of 440 mg iodine/kg Lipiodol Ultra Fluid (approx. 3-fold higher than the maximum recommended clinical dose on a mg/kg basis).
(Category C)
The safety of Lipiodol Ultra Fluid during pregnancy has not been demonstrated and, therefore, should only be used in pregnancy if absolutely necessary and under strict medical supervision.
It must not be used for hysterosalpingography when pregnancy is suspected or confirmed.
The use of Lipiodol Ultra Fluid during pregnancy causes iodine transfer which probably interferes with the thyroid function of the foetus. It produces the potential risk of brain damage and permanent hypothyroidism and, therefore, requires supervision of thyroid function and careful medical monitoring of the neonate.
The occurrence of maternal hypothyroidism after hysterosalpingography procedure (see Section 4.4 Special Warnings and Precautions for Use, Specific warnings related to hysterosalpingography) and the possible long half-life of the product in the event of a successful pregnancy requires a surveillance of the newborn's thyroid function.
Infants born to women who received iodinated contrast media while pregnant should have testing for hypothyroidism in the neonatal period. Some patients were treated for hypothyroidism. See Section 4.4 Special Warnings and Precautions for Use, Paediatric use.
Lipiodol Ultra Fluid did not affect embryofetal and postnatal development in rats after a single intrauterine dose of 440 mg iodine/kg (approx. 3-fold higher than the maximum recommended clinical dose on a mg/kg basis). Lipiodol Ultra Fluid was not embryotoxic or teratogenic in rats after oral administration of 50 mg iodine/kg/day during gestation days 6 to 17, or in rabbits after 4-5 intermittent (once every three days) oral administration of 12.5 mg iodine/kg during gestation days 6 to 18. In rats, increased incidences of dilated renal pelvis and ureter were observed at oral doses of 110 and 250 mg iodine/kg/day and increased incidence of kinked ureter at 250 mg/kg/day.
Pharmacokinetic studies have shown significant secretion of iodine in breast milk after intramuscular administration of Lipiodol Ultra Fluid. It has been demonstrated that the iodine enters the vascular system of the breastfed infant via the gastrointestinal tract and this could interfere with thyroid function. Consequently, breastfeeding should be discontinued if Lipiodol Ultra Fluid must be used.

4.7 Effects on Ability to Drive and Use Machines

No studies on the effects of Lipiodol Ultra Fluid on the ability to drive and use machines have been performed.

4.8 Adverse Effects (Undesirable Effects)

Adverse effects not related to a specific indication.

Most adverse reactions are dose related and consequently the dose should be as low as possible.
The use of Lipiodol Ultra Fluid causes a foreign body reaction with the formation of macrophages and foreign-body giant cells and the occurrence of sinus catarrh, plasmacytosis and subsequent connective tissue changes in the lymph nodes. Healthy lymph nodes tolerate the resulting reduced transport capacity. In previously damaged or hypoplastic lymph nodes, these changes can exacerbate the existing lymphostasis.
Hypersensitivity reactions are possible. These reactions may involve one or more effects, occurring concomitantly or successively, and usually including cutaneous, respiratory and/or cardiovascular manifestations, each of which can be a warning sign of incipient shock and, in very rare instances, can even prove fatal.
Severe allergic reactions have occurred in patients with a hypersensitivity to iodine so adrenaline and oxygen should be available at the time of administration and the patient pretested for allergy. Other dangers include oil embolism and venous intravasation.

Adverse effects related to a specific indication.

In diagnostic radiology.

Lymphography.

A large increase in temperature followed by a fever of 38 to 39°C may occur within 24 hours following the examination.
Oil microemboli can occur, with or without clinical symptoms. In very rare cases, they may resemble emboli in appearance and size. They appear as punctiform opacities on radiographic images of the lungs. Transient increases in temperature are possible.
Oil microemboli usually occur following an overdose of contrast agent or excessively rapid infusion. They are favoured by anatomic abnormalities such as lymphovenous fistulas or decreased lymph node uptake capacity (e.g. in elderly patients or after radiotherapy or cytostatic therapy).
Patients with a right-to-left cardiac shunts and those with a massive pulmonary embolism are particularly at risk of oil micro-emboli.

Hysterosalpingography.

Transitory fever reactions usually below 38°C accompanied by pelvic pain are frequent. Episodes of salpingitis or pelvic peritonitis have been reported after the procedure in case of latent infection. Granuloma type tissue reactions are rare but could be serious during the procedure as they produce a risk of perforation.
Hypothyroidism may also occur especially in patients with subclinical hypothyroidism. Following maternal exposure with Lipiodol Ultra Fluid, foetal thyroid disorders including foetal goitre were also reported.
Intravasation of Lipiodol Ultra Fluid may occur in the course of hysterosalpingography procedure and may result in serious pulmonary or cerebral embolic complications.
In interventional radiology.

Trans-arterial chemo-embolisation.

Most adverse reactions are not caused by Lipiodol Ultra Fluid but are due to anticancer medications or the embolisation itself. Procedural risks associated with catheterisation include vascular complications and infections.
The most frequent adverse reactions associated with Lipiodol Ultra Fluid in the context of trans-arterial chemo-embolisation are part of the postembolisation syndrome (fever, abdominal pain, nausea, vomiting and transitory changes in liver function). These reactions may also be induced by the anticancer medications or by the procedure itself.
The worsening of a pre-existing hepatocellular insufficiency can occur following the use of Lipiodol Ultra Fluid in the context of trans-arterial chemo-embolisation and may exceptionally lead to the occurrence of serious and potentially fatal complications such as hepatic encephalopathy, liver abscess, hepatic infarction, ascites, pancreatitis, or even necrotising pancreatitis.
Further serious adverse events associated with uncontrolled dissemination of Lipiodol Ultra Fluid in various organs includes pulmonary, cerebral (which could lead to cerebral infarction) or skin embolisms (which could lead to skin necrosis) may also occur. Massive pulmonary embolism has been associated with serious complications including dyspnoea, pulmonary oedema, plural effusion, acute respiratory distress syndrome, and pneumonitis.

Frequencies adverse effects.

The adverse effects (regardless of indication) are presented in Table 1, by system organ class and by frequency using the following categories: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon (≥ 1/1000 to < 1/100), rare (≥ 1/10,000 to < 1/1000), very rare (< 1/10,000), unknown (cannot be estimated from the available data).

Undesirable effects in paediatrics.

The expected nature of the undesirable effects connected with Lipiodol Ultra Fluid is the same as that of the effects reported in adults. Their frequency cannot be estimated from the available data.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

Overdose may lead to respiratory, cardiac or cerebral complications, which can potentially be fatal. Microembolisms may occur more frequently in the context of overdose.
Management of overdose consists in initiating symptomatic treatment and maintaining vital functions in the shortest possible timeframe.
Sites performing contrast medium examinations must be equipped with medicines and equipment for emergency aid.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Clinical trials.

Trans-arterial chemo-embolisation.

Used in trans-arterial chemo-embolisation (TACE) by selective intra-arterial hepatic injection, Lipiodol Ultra Fluid allows visualisation and control of the procedure due to its opacifying properties. In literature reports, after close-arterial injection to the liver, selective retention of Lipiodol Ultra Fluid within HCC nodules has been shown for up to 6 to 12 months on computed tomography scans.

Hysterosalpingography.

Used in hysterosalpingography, in women with infertility for more than 1 year, randomly assigned to hysterosalpingography with Lipiodol Ultra Fluid (n=73) or no hysterosalpingography (n=85), the pregnancy rate at 6 months follow-up was 38.4% (28/73) and 16.5% (14/85), respectively (p=0.002) and the live birth rate was 31.5% (23/73) and 12.9% (11/85), respectively (p=0.005). In women with infertility for more than 1 year, randomly assigned to hysterosalpingography with Lipiodol Ultra Fluid (n=554) or hysterosalpingography with water soluble iodinated contrast agent (n=554), the pregnancy rate at 6 months follow-up was 39.7% (220/554) and 29.1% (161/554), respectively (p < 0.001) and the live birth rate was 38.8% (214/552) and 28.1% (155/552), respectively (p=0.005). A meta-analysis of randomised controlled trials showed an overall odds ratio (OR) for pregnancy within 6 months after the procedure significantly in favour of hysterosalpingography with Lipiodol Ultra Fluid: OR of 3.47 [95% CI: 1.98; 6.08] when compared to no hysterosalpingography (p < 0.001, 3 studies, 382 women) and OR of 1.59 [95% CI: 1.28; 1.98] when compared to hysterosalpingography with water soluble iodinated contrast agent (p < 0.001, 4 studies, 1510 women).
The mechanisms underlying these differences are not well characterised. The following hypotheses have been proposed:
mechanical effect: tubal flushing of debris out of the fallopian tubes;
endometrial bathing effect;
immunologic effect: inhibition of peritoneal macrophages.

5.2 Pharmacokinetic Properties

After selective intra-arterial injection.

The iodine is eliminated mainly in the urine. After selective intra-arterial injection into the hepatic artery for the diagnosis of hepatic lesions or in trans-arterial chemo-embolisation of hepatocellular carcinoma, Lipiodol Ultra Fluid is significantly more concentrated in the tumour than in the healthy liver tissue.
Following intra-arterial administration of Lipiodol Ultra Fluid, iodised oil retained in normal hepatic parenchyma is phagocytised by the Kupffer cells of the liver and washed out via the hepatic lymphatic system in about 2 to 4 weeks. In HCC, retention in the liver tumour is prolonged, allowing re-imaging of the tumour for four weeks or longer.

After intrauterine injection.

After intrauterine injection in rats, Lipiodol Ultra Fluid migrates through the fallopian tubes to the ovaries and peritoneal cavity from which it is resorbed. The Tmax in plasma is reached around 8 hours post-administration. Half-life in plasma was about 18 hours. After 7 days, 48% of injected dose was eliminated (37% in urine, 11% in faeces). The two most exposed organs/tissues, distant from the administration site, were the thyroid and brown fat. The elimination from ovaries was fast, but was very slow from thyroid and brown fat.

5.3 Preclinical Safety Data

Genotoxicity.

Lipiodol Ultra Fluid is non-genotoxic based on negative results in a bacterial reverse mutation assay (in vitro), a mouse lymphoma forward mutation assay (in vitro), and an in vivo micronucleus bone marrow assay in rats after intravenous injection of Lipiodol at 479 mg iodine/kg.

Carcinogenicity.

Long-term studies in animals have not been performed to evaluate the carcinogenic potential of Lipiodol Ultra Fluid.
